      Specified by:
      getID in interface JavaMonitor
      Returns:
      The pointer which uniquely identifies this monitor in memory.

    • getName

      public String getName() throws CorruptDataException
      Description copied from interface: JavaMonitor
      Note that the name of a JavaMonitor is not necessarily meaningful but is provided here as it is usually present in the running VM. If there is no name for the monitor a synthetic name will be created by DTFJ.
      Specified by:
      getName in interface JavaMonitor
      Returns:
      the name of the monitor (never null)

      Specified by:
      getNotifyWaiters in interface JavaMonitor
      Returns:
      an iterator over the collection of threads waiting to be notified on this monitor

    • getObject

      public JavaObject getObject()
      Description copied from interface: JavaMonitor
      Get the object associated with this monitor.
      Specified by:
      getObject in interface JavaMonitor
      Returns:
      the object associated with this monitor, or null if this is a raw monitor or a valid object could not be retrieved.

    • equals

      public boolean equals(Object obj)
      Description copied from class: java.lang.Object
      Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison. The implementation in Object answers true only if the argument is the exact same object as the receiver (==).
      Specified by:
      equals in interface JavaMonitor
      Overrides:
      equals in class Object
      Parameters:
      obj - Object the object to compare with this object.
      Returns:
      boolean true if the object is the same as this object false if it is different from this object.

    • hashCode

      public int hashCode()
      Description copied from class: java.lang.Object
      Answers an integer hash code for the receiver. Any two objects which answer true when passed to .equals must answer the same value for this method.
      Specified by:
      hashCode in interface JavaMonitor
      Overrides:
      hashCode in class Object
      Returns:
      the receiver's hash.
