Get the set of threads waiting to be notified on the monitor (in the Object.wait method)- Specified by:
getNotifyWaiters
in interfaceJavaMonitor
- Returns:
- an iterator over the collection of threads waiting to be notified on this monitor

getObject
Description copied from interface:JavaMonitor
Get the object associated with this monitor.- Specified by:
getObject
in interfaceJavaMonitor

- the object associated with this monitor, or null if this is a raw monitor or a valid object could not be retrieved.
-
getOwner
Description copied from interface:JavaMonitor
Get the thread which currently owns the monitor- Specified by:
getOwner

- Returns:
- the owner of the monitor, or null if the monitor is unowned
- Throws:
CorruptDataException
-
equals
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 interfaceJavaMonitor
- Overrides:
equals
in classObject
- Parameters:
obj
-- Returns:
- True if the given object refers to the same Java Monitor in the image
- See Also:
-
hashCode
public int hashCode()Description copied from class:java.lang.Object
Answers an integer hash code for the receiver. Any two objects which answertrue
when passed to.equals
must answer the same value for this method.- Specified by:
hashCode
in interfaceJavaMonitor
- Overrides:
hashCode
in classObject
- Returns:
- the receiver's hash.
