public class MBeanConstructorInfo extends MBeanFeatureInfo implements Cloneable
Describes a constructor exposed by an MBean. Instances of this class are immutable. Subclasses may be mutable but this is not recommended.
description, name
public MBeanConstructorInfo(String description, Constructor<?> constructor)
Constructs an MBeanConstructorInfo
object. The Descriptor
of the constructed object will include fields contributed by any annotations on the Constructor
object that contain the DescriptorKey
meta-annotation.
description
- A human readable description of the operation.constructor
- The java.lang.reflect.Constructor
object describing the MBean constructor.public MBeanConstructorInfo(String name, String description, MBeanParameterInfo[] signature)
Constructs an MBeanConstructorInfo
object.
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.public MBeanConstructorInfo(String name, String description, MBeanParameterInfo[] signature, Descriptor descriptor)
Constructs an MBeanConstructorInfo
object.
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.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.
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 referenced MBeanParameterInfo
object is not copied.
MBeanParameterInfo
objects.public String toString()
Description copied from class: Object
Returns a string representation of the object. In general, the toString
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 class Object
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())
public boolean equals(Object o)
Compare this MBeanConstructorInfo to another.
equals
in class MBeanFeatureInfo
o
- the object to compare to.o
is an MBeanConstructorInfo such that its MBeanFeatureInfo.getName()
, MBeanFeatureInfo.getDescription()
, getSignature()
, and MBeanFeatureInfo.getDescriptor()
values are equal (not necessarily identical) to those of this MBeanConstructorInfo. Two signature arrays are equal if their elements are pairwise equal.Object.hashCode()
, HashMap
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 by HashMap
.
The general contract of hashCode
is:
hashCode
method must consistently return the same integer, provided no information used in equals
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. equals(Object)
method, then calling the hashCode
method on each of the two objects must produce the same integer result. Object.equals(java.lang.Object)
method, then calling the hashCode
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 Java™ programming language.)
