Interface ProcessHandler

All Known Implementing Classes:

BreakpointRuntimeHandler, CommandRuntimeHandler

public interface ProcessHandler

Interface that is used by the DebugMonitor to decide several operational steps.

Field Summary

static int	INTERRUPT
static int	POP
static int	PUSH
static int	SHALL_HANDLE
static int	SUSPEND

Method Summary

boolean	isLastCall() if true, the handler has the last call and will be processed at the last handler
boolean	shallHandle(boolean lastState, java.lang.Object element, int flag) define if an element shall be considered or completely ignored for suspension in a debug process. It should be implemented as a filter.
boolean	shallInterrupt(boolean lastState) define if the debugger runtime process shall be interrupted
boolean	shallSuspend(boolean lastState, java.lang.Object element, int flag) define if a debug process shall be suspended for a given element. It should be implemented as a filter.

Method Detail

shallHandle

boolean shallHandle(boolean lastState,
                    java.lang.Object element,
                    int flag)

define if an element shall be considered or completely ignored for suspension in a debug process.
It should be implemented as a filter. The result shall be AND or OR related with lastState.

Parameters:

lastState - the consolidated decisions of previously asked listeners

element - the element that is questioned

flag - one of the values IProcessHandler.PUSH or IProcessHandler.POP

Returns:

shallSuspend

boolean shallSuspend(boolean lastState,
                     java.lang.Object element,
                     int flag)

define if a debug process shall be suspended for a given element.
It should be implemented as a filter. The result shall be AND or OR related with lastState.

Parameters:

lastState - the consolidated decisions of previously asked listeners

element - the element that is questioned

flag - one of the values IEventHandler.NORMAL_FRAME or IEventHandler.END_FRAME

Returns:

if the process shall suspend based on the last state and the evaluation of the current element

shallInterrupt

boolean shallInterrupt(boolean lastState)

define if the debugger runtime process shall be interrupted

Parameters:

lastState - the consolidated decisions of previously asked listeners

Returns:

if the process shall be interrupted based on the last state and the evaluation of the current element

isLastCall

boolean isLastCall()

if true, the handler has the last call and will be processed at the last handler

Returns:

whether or not
