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.

See Also:

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
