MBeanConstructorInfo
public MBeanConstructorInfo(String description, Constructor<?> constructor)
Constructs anMBeanConstructorInfo
object. TheDescriptor
of the constructed object will include fields contributed by any annotations on theConstructor
object that contain theDescriptorKey
meta-annotation.- Parameters:
description
- A human readable description of the operation.constructor
- Thejava.lang.reflect.Constructor
object describing the MBean constructor.
-
MBeanConstructorInfo
public MBeanConstructorInfo(String name, String description, MBeanParameterInfo[] signature)
Constructs anMBeanConstructorInfo
object.- Parameters:
name
- The name of the constructor.signature
-MBeanParameterInfo
objects describing the parameters(arguments) of the constructor. This may be null with the same effect as a zero-length array.description
- A human readable description of the constructor.
-
MBeanConstructorInfo
public MBeanConstructorInfo(String name, String description, MBeanParameterInfo[] signature, Descriptor descriptor)
Constructs anMBeanConstructorInfo
object.- Parameters:
name
- The name of the constructor.signature
-MBeanParameterInfo
objects describing the parameters(arguments) of the constructor. This may be null with the same effect as a zero-length array.description
- A human readable description of the constructor.descriptor
- The descriptor for the constructor. This may be null which is equivalent to an empty descriptor.- Since:
- 1.6

Method Detail
-
clone
public Object clone()
Returns a shallow clone of this instance. The clone is obtained by simply calling super.clone(), thus calling the default native shallow cloning mechanism implemented by Object.clone(). No deeper cloning of any internal field is made.
Since this class is immutable, cloning is chiefly of interest to subclasses.
-
getSignature
public MBeanParameterInfo[] getSignature()
Returns the list of parameters for this constructor. Each parameter is described by an
MBeanParameterInfo
object.The returned array is a shallow copy of the internal array, which means that it is a copy of the internal array of references to the
MBeanParameterInfo
objects but that each referencedMBeanParameterInfo
object is not copied.- Returns:
- An array of
MBeanParameterInfo
objects.
-
toString
public String toString()
Description copied from class:Object
Returns a string representation of the object. In general, thetoString
method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.The
toString
method for classObject
returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@
', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:getClass().getName() + '@' + Integer.toHexString(hashCode())
-
equals
public boolean equals(Object o)
Compare this MBeanConstructorInfo to another.- Overrides:
equals
in classMBeanFeatureInfo
- Parameters:
o
- the object to compare to.- Returns:
- true if and only if
o
is an MBeanConstructorInfo such that itsMBeanFeatureInfo.getName()
,MBeanFeatureInfo.getDescription()
,getSignature()
, andMBeanFeatureInfo.getDescriptor()
values are equal (not necessarily identical) to those of this MBeanConstructorInfo. Two signature arrays are equal if their elements are pairwise equal. - See Also:
Object.hashCode()
,HashMap
-
hashCode
public int hashCode()
Description copied from class:Object
Returns 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
hashCode
is:- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons 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 thehashCode
method 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 thehashCode
method 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
Object
does 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:
hashCode
in classMBeanFeatureInfo
- Returns:
- a hash code value for this object.

Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)

an execution of a Java application, the
