Constructor Detail

MBeanConstructorInfo

public MBeanConstructorInfo(String description,
                            Constructor constructor)

Constructs an MBeanConstructorInfo object.

Parameters:

description - A human readable description of the operation.

constructor - The java.lang.reflect.Constructor object describing the MBean constructor.

MBeanConstructorInfo

public MBeanConstructorInfo(String name,
                            String description,
                            MBeanParameterInfo[] signature)
                     throws IllegalArgumentException

Constructs an MBeanConstructorInfo 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.

Throws:

IllegalArgumentException

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.

Overrides:

clone in class Object

Returns:

a clone of this instance.

Cloneable

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 referenced MBeanParameterInfo object is not copied.

Returns:

An array of MBeanParameterInfo objects.

equals

public boolean equals(Object o)

Compare this MBeanConstructorInfo to another.

Overrides:

equals in class MBeanFeatureInfo

Parameters:

o - the object to compare to.

Returns:

true iff o is an MBeanConstructorInfo such that its MBeanFeatureInfo.getName(), MBeanFeatureInfo.getDescription(), and getSignature() values are equal (not necessarily identical) to those of this MBeanConstructorInfo. Two signature arrays are equal if their elements are pairwise equal.

Object.hashCode(), Hashtable

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 hashtables such as those provided by java.util.Hashtable.

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 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.
• If two objects are equal according to the equals(Object) method, then calling the hashCode 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 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 hashtables.

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^TM programming language.)

Overrides:

hashCode in class MBeanFeatureInfo

Returns:

a hash code value for this object.
