public class MBeanFeatureInfo extends Object implements Serializable, DescriptorRead
Provides general information for an MBean descriptor object. The feature described can be an attribute, an operation, a parameter, or a notification. Instances of this class are immutable. Subclasses may be mutable but this is not recommended.

Field Detail

name
protected String name
The name of the feature. It is recommended that subclasses callgetName()rather than reading this field, and that they not change it.
-
description
protected String description
The human-readable description of the feature. It is recommended that subclasses callgetDescription()rather than reading this field, and that they not change it.

MBeanFeatureInfo
public MBeanFeatureInfo(String name, String description)
Constructs anMBeanFeatureInfoobject. This constructor is equivalent toMBeanFeatureInfo(name, description, (Descriptor) null.- Parameters:
name- The name of the feature.description- A human readable description of the feature.
-
MBeanFeatureInfo
public MBeanFeatureInfo(String name, String description, Descriptor descriptor)
Constructs anMBeanFeatureInfoobject.- Parameters:
name- The name of the feature.description- A human readable description of the feature.descriptor- The descriptor for the feature. This may be null which is equivalent to an empty descriptor.- Since:
- 1.6
-
-
Method Detail
-
getName
public String getName()
Returns the name of the feature.- Returns:
- the name of the feature.
-
getDescription
public String getDescription()
Returns the human-readable description of the feature.- Returns:
- the human-readable description of the feature.
-
getDescriptor
public Descriptor getDescriptor()
Returns the descriptor for the feature. Changing the returned value will have no affect on the original descriptor.- Specified by:
getDescriptorin interfaceDescriptorRead- Returns:
- a descriptor that is either immutable or a copy of the original.
- Since:
- 1.6
-
equals
public boolean equals(Object o)
Compare this MBeanFeatureInfo to another.- Overrides:
equalsin classObject- Parameters:
o- the object to compare to.- Returns:
- true if and only if
ois an MBeanFeatureInfo such that itsgetName(),getDescription(), andgetDescriptor()values are equal (not necessarily identical) to those of this MBeanFeatureInfo. - See Also:
Object.hashCode(),HashMap
-
hashCode
public int hashCode()
Description copied from class:ObjectReturns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided byHashMap.The general contract of
hashCodeis:- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals(Object)method, then calling thehashCodemethod on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
Object.equals(java.lang.Object)method, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by class
Objectdoes return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)- Overrides:
hashCodein classObject- Returns:
- a hash code value for this object.
