Method Summary

Modifier and Type	Method	Description
protected static void	clearAllBreakpoints()
static boolean	isDebugMode()	Returns current debug mode. Holds lazy initialized internal reference to improve performance. Therefore you can't change System property "mvel.debugger" after isDebugMode is called at least once. To update debug mode at runtime use setDebugMode(boolean)
static void	receiveBreakpoints()	Notify remote debugger that runtime is ready to get latest breakpoint information
protected static void	registerBreakpoint(String sourceName, int lineNumber)
protected static void	removeBreakpoint(String sourceName, int lineNumber)
static void	setDebugMode(boolean b)	Sets debug mode on/off. Updates local MVELDebugHandler property and System property "mvel.debugger" There's no need to ever call this method unless you write junit tests!
protected static void	setOnBreakReturn(int value)

Method Detail

receiveBreakpoints

public static void receiveBreakpoints()

Notify remote debugger that runtime is ready to get latest breakpoint information

registerBreakpoint

protected static final void registerBreakpoint(String sourceName,
                                               int lineNumber)

clearAllBreakpoints

protected static final void clearAllBreakpoints()

removeBreakpoint

protected static final void removeBreakpoint(String sourceName,
                                             int lineNumber)

setOnBreakReturn

protected static final void setOnBreakReturn(int value)

isDebugMode

public static boolean isDebugMode()

Returns current debug mode.
Holds lazy initialized internal reference to improve performance.
Therefore you can't change System property "mvel.debugger" after isDebugMode is called at least once.

To update debug mode at runtime use setDebugMode(boolean)

Returns:

true if debug mode is enabled.

setDebugMode

public static void setDebugMode(boolean b)

Sets debug mode on/off.
Updates local MVELDebugHandler property and System property "mvel.debugger"

There's no need to ever call this method unless you write junit tests!

Parameters:

b - is Debug enabled?
