Constructor Detail

PendingRequestManager

public PendingRequestManager(JPDADebugger manager)

Method Detail

addPendingRequest

public void addPendingRequest(DocumentDebugAction<?> action)

Called if a breakpoint is set before its class is prepared

Parameters:

action - The DebugAction that is pending

removePendingRequest

public void removePendingRequest(DocumentDebugAction<?> action)

Called if a breakpoint is set and removed before its class is prepared

Parameters:

action - The DebugAction that was set and removed

classPrepared

public void classPrepared(com.sun.jdi.event.ClassPrepareEvent event)
                   throws DebugException

Called by the EventHandler whenever a ClassPrepareEvent occurs. This will take the event, get the class that was prepared, lookup the Vector of DebugAction that was waiting for this class's preparation, iterate through this Vector, and attempt to create the Breakpoints that were pending. Since the keys to the Hashtable are the names of the outer class, the $ and everything after it must be cropped off from the class name in order to do the lookup. During the lookup, however, the line number of each action is checked to see if the line number is contained in the given event's ReferenceType. If not, we ignore that pending action since it is not in the class that was just prepared, but may be in one of its inner classes.

Parameters:

event - The ClassPrepareEvent that just occured

Throws:

DebugException
