Interface ObjectVariable

All Superinterfaces:: Variable

All Known Subinterfaces:: Super, This

public interface ObjectVariable
extends Variable

Represents instance of some object in debugged JVM. This interface can be optionally inplemented by a implementation of LocalVariable or Field interfaces.

 Since JDI interfaces evolve from one version to another, it's strongly recommended
 not to implement this interface in client code. New methods can be added to
 this interface at any time to keep up with the JDI functionality.

See Also:: LocalVariable, Field, This, Super, JPDAThread.getContendedMonitor(), JPDAThread.getOwnedMonitors()
