Class MBeanParameterInfo

java.lang.Object
  javax.management.MBeanFeatureInfo
      javax.management.MBeanParameterInfo

All Implemented Interfaces:

Serializable , Cloneable , DescriptorRead

Direct Known Subclasses:

OpenMBeanParameterInfoSupport

public class MBeanParameterInfo
extends MBeanFeatureInfo
implements Cloneable

Describes an argument of an operation exposed by an MBean. Instances of this class are immutable. Subclasses may be mutable but this is not recommended.

MBeanParameterInfo ( String  name, String  type, String  description, Descriptor           Constructs an a MBeanParameterInfo object.

MBeanParameterInfo

public MBeanParameterInfo(String name,
                          String type,
                          String description)

Constructs an a MBeanParameterInfo object.

Parameters:

name - The name of the data

type - The type or class name of the data

description - A human readable description of the data. Optional.

MBeanParameterInfo

public MBeanParameterInfo(String name,
                          String type,
                          String description,
                          Descriptor descriptor)

Constructs an a MBeanParameterInfo object.

Parameters:

name - The name of the data

type - The type or class name of the data

description - A human readable description of the data. Optional.

descriptor - The descriptor for the operation. This may be null which is equivalent to an empty descriptor. This may be null in which case the operation's descriptor will be empty.

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

getType

public String getType()

Returns the type or class name of the data.

Returns:

the type string.

toString

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())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.

equals

public boolean equals(Object o)

Compare this MBeanParameterInfo to another.

Overrides:

equals in class MBeanFeatureInfo

Parameters:

o - the object to compare to.

Returns:

true if and only if iff o is an MBeanParameterInfo such that its MBeanFeatureInfo.getName() , getType() , MBeanFeatureInfo.getDescriptor() , and MBeanFeatureInfo.getDescription() values are equal (not necessarily identical) to those of this MBeanParameterInfo.

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.
