All Superinterfaces:

MBeanServerConnection

All Known Subinterfaces:

MBeanServerForwarder
```
public interface MBeanServer
extends MBeanServerConnection
```
This is the interface for MBean manipulation on the agent side. It contains the methods necessary for the creation, registration, and deletion of MBeans as well as the access methods for registered MBeans. This is the core component of the JMX infrastructure.

User code does not usually implement this interface. Instead, an object that implements this interface is obtained with one of the methods in the MBeanServerFactory class.

Every MBean which is added to the MBean server becomes manageable: its attributes and operations become remotely accessible through the connectors/adaptors connected to that MBean server. A Java object cannot be registered in the MBean server unless it is a JMX compliant MBean.

When an MBean is registered or unregistered in the MBean server a MBeanServerNotification Notification is emitted. To register an object as listener to MBeanServerNotifications you should call the MBean server method addNotificationListener with ObjectName the ObjectName of the MBeanServerDelegate. This ObjectName is:
JMImplementation:type=MBeanServerDelegate.

An object obtained from the createMBeanServer or newMBeanServer methods of the MBeanServerFactory class applies security checks to its methods, as follows.

First, if there is no security manager (System.getSecurityManager() is null), then an implementation of this interface is free not to make any checks.

Assuming that there is a security manager, or that the implementation chooses to make checks anyway, the checks are made as detailed below. In what follows, and unless otherwise specified, className is the string returned by MBeanInfo.getClassName() for the target MBean.

If a security check fails, the method throws SecurityException.

For methods that can throw InstanceNotFoundException, this exception is thrown for a non-existent MBean, regardless of permissions. This is because a non-existent MBean has no className.
- For the invoke method, the caller's permissions must imply MBeanPermission(className, operationName, name, "invoke").
- For the getAttribute method, the caller's permissions must imply MBeanPermission(className, attribute, name, "getAttribute").
- For the getAttributes method, the caller's permissions must imply MBeanPermission(className, null, name, "getAttribute"). Additionally, for each attribute a in the AttributeList, if the caller's permissions do not imply MBeanPermission(className, a, name, "getAttribute"), the MBean server will behave as if that attribute had not been in the supplied list.
- For the setAttribute method, the caller's permissions must imply MBeanPermission(className, attrName, name, "setAttribute"), where attrName is attribute.getName().
- For the setAttributes method, the caller's permissions must imply MBeanPermission(className, null, name, "setAttribute"). Additionally, for each attribute a in the AttributeList, if the caller's permissions do not imply MBeanPermission(className, a, name, "setAttribute"), the MBean server will behave as if that attribute had not been in the supplied list.
- For the addNotificationListener methods, the caller's permissions must imply MBeanPermission(className, null, name, "addNotificationListener").
- For the removeNotificationListener methods, the caller's permissions must imply MBeanPermission(className, null, name, "removeNotificationListener").
- For the getMBeanInfo method, the caller's permissions must imply MBeanPermission(className, null, name, "getMBeanInfo").
- For the getObjectInstance method, the caller's permissions must imply MBeanPermission(className, null, name, "getObjectInstance").
- For the isInstanceOf method, the caller's permissions must imply MBeanPermission(className, null, name, "isInstanceOf").
- For the queryMBeans method, the caller's permissions must imply MBeanPermission(null, null, null, "queryMBeans"). Additionally, for each MBean n that matches name, if the caller's permissions do not imply MBeanPermission(className, null, n, "queryMBeans"), the MBean server will behave as if that MBean did not exist.
  
  Certain query elements perform operations on the MBean server. If the caller does not have the required permissions for a given MBean, that MBean will not be included in the result of the query. The standard query elements that are affected are Query.attr(String), Query.attr(String,String), and Query.classattr().
- For the queryNames method, the checks are the same as for queryMBeans except that "queryNames" is used instead of "queryMBeans" in the MBeanPermission objects. Note that a "queryMBeans" permission implies the corresponding "queryNames" permission.
- For the getDomains method, the caller's permissions must imply MBeanPermission(null, null, null, "getDomains"). Additionally, for each domain d in the returned array, if the caller's permissions do not imply MBeanPermission(null, null, new ObjectName("d:x=x"), "getDomains"), the domain is eliminated from the array. Here, x=x is any key=value pair, needed to satisfy ObjectName's constructor but not otherwise relevant.
- For the getClassLoader method, the caller's permissions must imply MBeanPermission(className, null, loaderName, "getClassLoader").
- For the getClassLoaderFor method, the caller's permissions must imply MBeanPermission(className, null, mbeanName, "getClassLoaderFor").
- For the getClassLoaderRepository method, the caller's permissions must imply MBeanPermission(null, null, null, "getClassLoaderRepository").
- For the deprecated deserialize methods, the required permissions are the same as for the methods that replace them.
- For the instantiate methods, the caller's permissions must imply MBeanPermission(className, null, null, "instantiate"), where className is the name of the class which is to be instantiated.
- For the registerMBean method, the caller's permissions must imply MBeanPermission(className, null, name, "registerMBean").
  If the MBeanPermission check succeeds, the MBean's class is validated by checking that its ProtectionDomain implies MBeanTrustPermission("register").
  
  Finally, if the name argument is null, another MBeanPermission check is made using the ObjectName returned by MBeanRegistration.preRegister.
- For the createMBean methods, the caller's permissions must imply the permissions needed by the equivalent instantiate followed by registerMBean.
- For the unregisterMBean method, the caller's permissions must imply MBeanPermission(className, null, name, "unregisterMBean").

```
    Instantiates and registers an MBean in the MBean server. The MBean server will use its Default Loader Repository to load the class of the MBean. An object name is associated with the MBean. If the object name given is null, the MBean must provide its own name by implementing the MBeanRegistration interface and returning the name from the preRegister method.
    
    This method is equivalent to createMBean(className, name, (Object[]) null, (String[]) null).
    
    If this method successfully creates an MBean, a notification is sent as described above.
    
    Specified by:
    
    createMBean in interface MBeanServerConnection
    
    Parameters:
    className - The class name of the MBean to be instantiated.
    name - The object name of the MBean. May be null.
    
    Returns:
    An ObjectInstance, containing the ObjectName and the Java class name of the newly instantiated MBean. If the contained ObjectName is n, the contained Java class name is getMBeanInfo(n).getClassName().
    
    Throws:
    
    RuntimeOperationsException - Wraps a java.lang.IllegalArgumentException: The className passed in parameter is null, the ObjectName passed in parameter contains a pattern or no ObjectName is specified for the MBean.
    
    RuntimeMBeanException - If the MBean's constructor or its preRegister or postRegister method threw a RuntimeException. If the postRegister (MBeanRegistration interface) method of the MBean throws a RuntimeException, the createMBean method will throw a RuntimeMBeanException, although the MBean creation and registration succeeded. In such a case, the MBean will be actually registered even though the createMBean method threw an exception. Note that RuntimeMBeanException can also be thrown by preRegister, in which case the MBean will not be registered.
    
    RuntimeErrorException - If the postRegister (MBeanRegistration interface) method of the MBean throws an Error, the createMBean method will throw a RuntimeErrorException, although the MBean creation and registration succeeded. In such a case, the MBean will be actually registered even though the createMBean method threw an exception. Note that RuntimeErrorException can also be thrown by preRegister, in which case the MBean will not be registered.
    
    ReflectionException - Wraps a java.lang.ClassNotFoundException or a java.lang.Exception that occurred when trying to invoke the MBean's constructor.
    
    InstanceAlreadyExistsException - The MBean is already under the control of the MBean server.
    
    MBeanRegistrationException - The preRegister (MBeanRegistration interface) method of the MBean has thrown an exception. The MBean will not be registered.

In such a case, the MBean will be actually unregistered even though the unregisterMBean method threw an exception. Note that RuntimeMBeanException can also be thrown by preDeregister, in which case the MBean will remain registered.
    
    RuntimeErrorException - If the postDeregister (MBeanRegistration interface) method of the MBean throws an Error, the unregisterMBean method will throw a RuntimeErrorException, although the MBean unregistration succeeded. In such a case, the MBean will be actually unregistered even though the unregisterMBean method threw an exception. Note that RuntimeMBeanException can also be thrown by preDeregister, in which case the MBean will remain registered.
    
    InstanceNotFoundException - The MBean specified is not registered in the MBean server.

```
    Description copied from interface: MBeanServerConnection
    
    Gets the ObjectInstance for a given MBean registered with the MBean server.
    
    Specified by:
    
    getObjectInstance in interface MBeanServerConnection
    
    Parameters:
    name - The object name of the MBean.
    
    Returns:
    The ObjectInstance associated with the MBean specified by name. The contained ObjectName is name and the contained class name is getMBeanInfo(name).getClassName().
    
    Throws:
    
    InstanceNotFoundException - The MBean specified is not registered in the MBean server.
  - queryMBeans
```
Set<ObjectInstance> queryMBeans(ObjectName name,
                              QueryExp query)
```
    Gets MBeans controlled by the MBean server. This method allows any of the following to be obtained: All MBeans, a set of MBeans specified by pattern matching on the ObjectName and/or a Query expression, a specific MBean. When the object name is null or no domain and key properties are specified, all objects are to be selected (and filtered if a query is specified). It returns the set of ObjectInstance objects (containing the ObjectName and the Java Class name) for the selected MBeans.
    
    Specified by:
    
    queryMBeans in interface MBeanServerConnection
    
    Parameters:
    name - The object name pattern identifying the MBeans to be retrieved. If null or no domain and key properties are specified, all the MBeans registered will be retrieved.
    query - The query expression to be applied for selecting MBeans. If null no query expression will be applied for selecting MBeans.
    
    Returns:
    A set containing the ObjectInstance objects for the selected MBeans. If no MBean satisfies the query an empty list is returned.
    
    Throws:

Set<ObjectName> queryNames(ObjectName name,
                         QueryExp query)
```
    Gets the names of MBeans controlled by the MBean server. This method enables any of the following to be obtained: The names of all MBeans, the names of a set of MBeans specified by pattern matching on the ObjectName and/or a Query expression, a specific MBean name (equivalent to testing whether an MBean is registered). When the object name is null or no domain and key properties are specified, all objects are selected (and filtered if a query is specified). It returns the set of ObjectNames for the MBeans selected.
    
    Specified by:
    
    queryNames in interface MBeanServerConnection
    
    Parameters:
    name - The object name pattern identifying the MBean names to be retrieved. If null or no domain and key properties are specified, the name of all registered MBeans will be retrieved.
    query - The query expression to be applied for selecting MBeans. If null no query expression will be applied for selecting MBeans.
    
    Returns:
    A set containing the ObjectNames for the MBeans selected. If no MBean satisfies the query, an empty list is returned.

```
    Description copied from interface: MBeanServerConnection
    Sets the values of several attributes of a named MBean. The MBean is identified by its object name.
    
    If one or more attributes cannot be set for some reason, they will be omitted from the returned AttributeList. The caller should check that the input AttributeList is the same size as the output one. To discover what problem prevented a given attribute from being retrieved, it will usually be possible to call setAttribute for that attribute, although this is not guaranteed to work. (For example, the values of two attributes may have been rejected because they were inconsistent with each other. Setting one of them alone might be allowed.)
    
    Here is an example of calling this method and checking that it succeeded in setting all the requested attributes:
```
 AttributeList inputAttrs = ...;
 AttributeList outputAttrs = mbeanServerConnection.setAttributes(objectName, inputAttrs);
 if (inputAttrs.size() == outputAttrs.size())
     System.out.println("All attributes were set successfully");
 else {
     List<String> missing = new ArrayList<String>();
     for (Attribute a : inputAttrs.asList())
         missing.add(a.getName());
     for (Attribute a : outputAttrs.asList())
         missing.remove(a.getName());
     System.out.println("Did not set: " + missing);
 }
 
```
    Specified by:
    
    setAttributes in interface MBeanServerConnection
    
    Parameters:
    name - The object name of the MBean within which the attributes are to be set.
    attributes - A list of attributes: The identification of the attributes to be set and the values they are to be set to.
    
    Returns:
    The list of attributes that were set, with their new values.
    
    Throws:
    
    RuntimeOperationsException - Wraps a java.lang.IllegalArgumentException: The object name in parameter is null or attributes in parameter is null.
    
    InstanceNotFoundException - The MBean specified is not registered in the MBean server.
    
    ReflectionException - An exception occurred when trying to invoke the getAttributes method of a Dynamic MBean.

                     ReflectionException
```
    Description copied from interface: MBeanServerConnection
    Invokes an operation on an MBean.
    
    Because of the need for a signature to differentiate possibly-overloaded operations, it is much simpler to invoke operations through an MBean proxy where possible. For example, suppose you have a Standard MBean interface like this:
```
 public interface FooMBean {
     public int countMatches(String[] patterns, boolean ignoreCase);
 }
 
```
    The countMatches operation can be invoked as follows:
```
 String[] myPatterns = ...;
 int count = (Integer) mbeanServerConnection.invoke(
         objectName,
         "countMatches",
         new Object[] {myPatterns, true},
         new String[] {String[].class.getName(), boolean.class.getName()});
 
```
    Alternatively, it can be invoked through a proxy as follows:
```
 String[] myPatterns = ...;
 FooMBean fooProxy = JMX.newMBeanProxy(
         mbeanServerConnection, objectName, FooMBean.class);
 int count = fooProxy.countMatches(myPatterns, true);
 
```
    Specified by:
    
    invoke in interface MBeanServerConnection
    
    Parameters:
    name - The object name of the MBean on which the method is to be invoked.
    operationName - The name of the operation to be invoked.
    params - An array containing the parameters to be set when the operation is invoked
    signature - An array containing the signature of the operation, an array of class names in the format returned by Class.getName(). The class objects will be loaded using the same class loader as the one used for loading the MBean on which the operation was invoked.
    
    Returns:
    The object returned by the operation, which represents the result of invoking the operation on the MBean specified.
    
    Throws:
    
    InstanceNotFoundException - The MBean specified is not registered in the MBean server.
    
    MBeanException - Wraps an exception thrown by the MBean's invoked method.
    
    ReflectionException - Wraps a java.lang.Exception thrown while trying to invoke the method.
  - getDefaultDomain
```
String getDefaultDomain()
```
    Description copied from interface: MBeanServerConnection
    
    Returns the default domain used for naming the MBean. The default domain name is used as the domain part in the ObjectName of MBeans if no domain is specified by the user.
    
    Specified by:
    
    getDefaultDomain in interface MBeanServerConnection
    
    Returns:
    the default domain.
  - getDomains
```
String[] getDomains()
```
    Description copied from interface: MBeanServerConnection
    
    Returns the list of domains in which any MBean is currently registered. A string is in the returned array if and only if there is at least one MBean registered with an ObjectName whose getDomain() is equal to that string. The order of strings within the returned array is not defined.
    
    Specified by:
    
    getDomains in interface MBeanServerConnection
    
    Returns:
    the list of domains.
  - addNotificationListener

                             throws InstanceNotFoundException
```
    Adds a listener to a registered MBean. Notifications emitted by the MBean will be forwarded to the listener.
    If the source of the notification is a reference to an MBean object, the MBean server will replace it by that MBean's ObjectName. Otherwise the source is unchanged.
    
    Specified by:
    
    addNotificationListener in interface MBeanServerConnection
    
    Parameters:
    name - The name of the MBean on which the listener should be added.
    listener - The listener object which will handle the notifications emitted by the registered MBean.
    filter - The filter object. If filter is null, no filtering will be performed before handling notifications.
    handback - The context to be sent to the listener when a notification is emitted.
    
    Throws:
    
    InstanceNotFoundException - The MBean name provided does not match any of the registered MBeans.

                             throws InstanceNotFoundException
```
    Adds a listener to a registered MBean.
    
    A notification emitted by an MBean will be forwarded by the MBeanServer to the listener. If the source of the notification is a reference to an MBean object, the MBean server will replace it by that MBean's ObjectName. Otherwise the source is unchanged.
    
    The listener object that receives notifications is the one that is registered with the given name at the time this method is called. Even if it is subsequently unregistered, it will continue to receive notifications.
    
    Specified by:
    
    addNotificationListener in interface MBeanServerConnection
    
    Parameters:
    name - The name of the MBean on which the listener should be added.
    listener - The object name of the listener which will handle the notifications emitted by the registered MBean.
    filter - The filter object. If filter is null, no filtering will be performed before handling notifications.
    handback - The context to be sent to the listener when a notification is emitted.
    
    Throws:
    
    RuntimeOperationsException - Wraps an IllegalArgumentException. The MBean named by listener exists but does not implement the NotificationListener interface.
    
    InstanceNotFoundException - The MBean name of the notification listener or of the notification broadcaster does not match any of the registered MBeans.

                     throws InstanceNotFoundException
```
    Description copied from interface: MBeanServerConnection
    
    Returns true if the MBean specified is an instance of the specified class, false otherwise.
    
    If name does not name an MBean, this method throws InstanceNotFoundException.
    
    Otherwise, let
    X be the MBean named by name,
    L be the ClassLoader of X,
    N be the class name in X's MBeanInfo.
    
    If N equals className, the result is true.
    
    Otherwise, if L successfully loads className and X is an instance of this class, the result is true.
    Otherwise, if L successfully loads both N and className, and the second class is assignable from the first, the result is true.
    
    Otherwise, the result is false.
    
    Specified by:
    
    isInstanceOf in interface MBeanServerConnection
    
    Parameters:
    name - The ObjectName of the MBean.
    className - The name of the class.
    
    Returns:
    true if the MBean specified is an instance of the specified class according to the rules above, false otherwise.
    
    Throws:

    This method is equivalent to instantiate(className, (Object[]) null, (String[]) null).
    
    Parameters:
    className - The class name of the object to be instantiated.
    
    Returns:
    The newly instantiated object.
    
    Throws:
    
    ReflectionException - Wraps a java.lang.ClassNotFoundException or the java.lang.Exception that occurred when trying to invoke the object's constructor.

    What this means is that the ClassLoader may be wrapped in another ClassLoader for security or other reasons.
    Throws:
    
    InstanceNotFoundException - if the named MBean is not found.
  - getClassLoader
```
ClassLoader getClassLoader(ObjectName loaderName)
