execute
public static Object execute(boolean debugger, CompiledExpression expression, Object ctx, VariableResolverFactory variableFactory) Main interpreter.- Parameters:
debugger
- Run in debug modeexpression
- The compiled expression objectctx
- The root context objectvariableFactory
- The variable factory to be injected- Returns:
- The resultant value
- See Also:
-
registerBreakpoint
Register a debugger breakpoint.- Parameters:
source
- - the source file the breakpoint is registered inline
- - the line number of the breakpoint
-
removeBreakpoint
Remove a specific breakpoint.- Parameters:
source
- - the source file the breakpoint is registered inline
- - the line number of the breakpoint to be removed
-
hasDebuggerContext
public static boolean hasDebuggerContext()Tests whether or not a debugger context exist.- Returns:
- boolean
-
ensureDebuggerContext
private static void ensureDebuggerContext()Ensures that debugger context exists. -
clearAllBreakpoints
public static void clearAllBreakpoints()Reset all the currently registered breakpoints. -
hasBreakpoints
public static boolean hasBreakpoints()Tests whether or not breakpoints have been declared.- Returns:
- boolean
-
setThreadDebugger
Sets the Debugger instance to handle breakpoints. A debugger may only be registered once per thread. Calling this method more than once will result in the second and subsequent calls to simply fail silently. To re-register the Debugger, you must callresetDebugger()
- Parameters:
debugger
- - debugger instance
-
resetDebugger
public static void resetDebugger()Reset all information registered in the debugger, including the actual attached Debugger and registered breakpoints.
