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 Summary |
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. |
ObjectInstance(String objectName,
String className)
Allows an object instance to be created given a string representation of
an object name and the full class name, including the package name. |
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.
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:
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
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.
