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.

    • 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.

    • 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

    • 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
