Class ObjectInstance

java.lang.Object

javax.management.ObjectInstance

All Implemented Interfaces:

Serializable

public class ObjectInstance
extends Object
implements Serializable

Used to represent the object name of an MBean and its class name. If the MBean is a Dynamic MBean the class name should be retrieved from the MBeanInfo it provides.

Since:

1.5

Constructor Details

ObjectInstance

public ObjectInstance(String objectName,
 String className)
               throws MalformedObjectNameException

Allows an object instance to be created given a string representation of an object name and the full class name, including the package name.

Parameters:

objectName - A string representation of the object name.

className - The full class name, including the package name, of the object instance. If the MBean is a Dynamic MBean the class name corresponds to its getMBeanInfo().getClassName().

Throws:

MalformedObjectNameException - The string passed as a parameter does not have the right format.

ObjectInstance

public ObjectInstance(ObjectName objectName,
 String className)

Allows an object instance to be created given an object name and the full class name, including the package name.

Parameters:

objectName - The object name.

className - The full class name, including the package name, of the object instance. If the MBean is a Dynamic MBean the class name corresponds to its getMBeanInfo().getClassName(). If the MBean is a Dynamic MBean the class name should be retrieved from the MBeanInfo it provides.

Method Details

equals

public boolean equals(Object object)

Compares the current object instance with another object instance.

Overrides:

equals in class Object

Parameters:

object - The object instance that the current object instance is to be compared with.

Returns:

True if the two object instances are equal, otherwise false.

• Object.hashCode()
• HashMap

hashCode

public int hashCode()

Description copied from class: Object

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by HashMap.

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 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 equals 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.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object

• System.identityHashCode(Object)

getObjectName

public ObjectName getObjectName()

Returns the object name part.

Returns:

the object name.

getClassName

public String getClassName()

Returns the class part.

Returns:

the class name.

toString

public String toString()

Returns a string representing this ObjectInstance object. The format of this string is not specified, but users can expect that two ObjectInstances return the same string if and only if they are equal.

Overrides:

toString in class Object

Returns:

a string representation of the object
