Method Detail

updateHit

public Action updateHit(Task task,
                        long address)

Description copied from interface: TaskObserver.Code

The task has hit the breakpoint. Return Action.BLOCK to block the task's further execution. Note that all Tasks of a Proc share their breakpoints, so this method needs to check the actual Task that got hit.

Specified by:

updateHit in interface TaskObserver.Code

getTriggered

public int getTriggered()

addFailed

public void addFailed(Object observable,
                      Throwable w)

Description copied from interface: Observer

Notify that the attempt to add to the specified observer failed.

Specified by:

addFailed in interface Observer

addedTo

public void addedTo(Object observable)

Description copied from interface: Observer

Acknowledge the request to add this Observer from Object's set of observers was successful.

Specified by:

addedTo in interface Observer

isAdded

public boolean isAdded()

deletedFrom

public void deletedFrom(Object observable)

Description copied from interface: Observer

Acknowledge the request to delete this Observer from Object's set of observers was successful (or that the Observer was spontaneously deleted, e.g., due to a task exit).

Specified by:

deletedFrom in interface Observer

isRemoved

public boolean isRemoved()

getAddress

public long getAddress()

addPersistentBreakpoint

public void addPersistentBreakpoint(Task task,
                                    Breakpoint.PersistentBreakpoint bp)

deletePersistentBreakpoint

public void deletePersistentBreakpoint(Task task,
                                       Breakpoint.PersistentBreakpoint bp)
