Method Detail

addBreakpoint

void addBreakpoint(Breakpoint breakpoint)

Add the given breakpoint

Parameters:

breakpoint - the breakpoint

addBreakpoint

void addBreakpoint(Breakpoint breakpoint,
                 Condition... conditions)

Add the given breakpoint

Parameters:

breakpoint - the breakpoint

conditions - a number of Conditions

addSingleStepBreakpoint

void addSingleStepBreakpoint(Breakpoint breakpoint)

Add the given breakpoint which will be used in single step mode

The debugger will single step the first message arriving.

Parameters:

breakpoint - the breakpoint

addSingleStepBreakpoint

void addSingleStepBreakpoint(Breakpoint breakpoint,
                           Condition... conditions)

Add the given breakpoint which will be used in single step mode

The debugger will single step the first message arriving.

Parameters:

breakpoint - the breakpoint

conditions - a number of Conditions

removeBreakpoint

void removeBreakpoint(Breakpoint breakpoint)

Removes the given breakpoint

Parameters:

breakpoint - the breakpoint

suspendAllBreakpoints

void suspendAllBreakpoints()

Suspends all breakpoints.

activateAllBreakpoints

void activateAllBreakpoints()

Activate all breakpoints.

getBreakpoints

List<Breakpoint> getBreakpoints()

Gets a list of all the breakpoints

Returns:

the breakpoints wrapped in an unmodifiable list, is never null.

startSingleStepExchange

boolean startSingleStepExchange(String exchangeId,
                              Breakpoint breakpoint)

Starts the single step debug mode for the given exchange

Parameters:

exchangeId - the exchange id

breakpoint - the breakpoint

Returns:

true if the debugger will single step the given exchange, false if the debugger is already single stepping another, and thus cannot simultaneously single step another exchange

stopSingleStepExchange

void stopSingleStepExchange(String exchangeId)

Stops the single step debug mode for the given exchange.

Notice: The default implementation of the debugger is capable of auto stopping when the exchange is complete.

Parameters:

exchangeId - the exchange id

beforeProcess

boolean beforeProcess(Exchange exchange,
                    Processor processor,
                    ProcessorDefinition<?> definition)

Callback invoked when an Exchange is about to be processed which allows implementators to notify breakpoints.

Parameters:

exchange - the exchange

processor - the Processor about to be processed

definition - the definition of the processor

Returns:

true if any breakpoint was hit, false if not breakpoint was hit

afterProcess

boolean afterProcess(Exchange exchange,
                   Processor processor,
                   ProcessorDefinition<?> definition,
                   long timeTaken)

Callback invoked when an Exchange has been processed which allows implementators to notify breakpoints.

Parameters:

exchange - the exchange

processor - the Processor which was processed

definition - the definition of the processor

timeTaken - time in millis it took to process the Exchange - time spend in breakpoint callbacks may affect this time

Returns:

true if any breakpoint was hit, false if not breakpoint was hit

onEvent

boolean onEvent(Exchange exchange,
              EventObject event)

Callback invoked when an Exchange is being processed which allows implementators to notify breakpoints.

Parameters:

exchange - the exchange

event - the event (instance of AbstractExchangeEvent

Returns:

true if any breakpoint was hit, false if not breakpoint was hit
