Constructor Detail

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 Detail

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(), 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:

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 JavaTM programming language.)

Overrides:
hashCode in class Object
Returns:
a hash code value for this object.
See Also:
Object.equals(java.lang.Object), Hashtable

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.
