Method Detail

traceObject

public ObjectReference traceObject(ObjectReference object,
                                   boolean root)

This method traces an object with knowledge of the fact that object is a root or not. In simple collectors the fact it is a root is not important so this is the default implementation given here.

Overrides:

traceObject in class TraceLocal

Parameters:

object - The object to be traced.

root - Is this object a root?

Returns:

The new reference to the same object instance.

willNotMoveInCurrentCollection

public boolean willNotMoveInCurrentCollection(ObjectReference object)

Will this object move from this point on, during the current trace?

Overrides:

willNotMoveInCurrentCollection in class TraceLocal

Parameters:

object - The object to query.

Returns:

true if the object will not move.
