Method Summary

Modifier and Type	Method and Description
Interpreter	getActiveInterpreter() Gets the active interpreter.
InterpreterStackTrace	getActiveInterpreterStackTrace() Gets the active interpreter stack trace.
boolean	getEvalMode() Returns the value of evaluation mode.
void	popFromStack(Expression expression, Interpreter activeInterpreter, InterpreterStackTrace interpreterStackTrace) Pops expression from the stack.
void	pushToStack(Expression expression, Interpreter activeInterpreter, InterpreterStackTrace interpreterStackTrace) Push expression to the stack.
void	setEvalMode(boolean b) Sets mode of evaluation of expressions.
void	stopOnBreakpointOrStep(Expression expression, Interpreter interpreter, InterpreterStackTrace stackTrace) Suspends the execution of a process if a breakpoint matching the expression is hit or if the current step conforms to the DebuggerAction request.

Method Detail

stopOnBreakpointOrStep

void stopOnBreakpointOrStep(Expression expression,
                            Interpreter interpreter,
                            InterpreterStackTrace stackTrace)

Suspends the execution of a process if a breakpoint matching the expression is hit or if the current step conforms to the DebuggerAction request.

Parameters:

expression -

interpreter -

stackTrace -

getEvalMode

boolean getEvalMode()

Returns the value of evaluation mode.

Returns:

the value of evaluation mode

setEvalMode

void setEvalMode(boolean b)

Sets mode of evaluation of expressions.

Parameters:

b -

pushToStack

void pushToStack(Expression expression,
                 Interpreter activeInterpreter,
                 InterpreterStackTrace interpreterStackTrace)

Push expression to the stack.

Parameters:

expression -

activeInterpreter - the interpreter which is used to interpret the expression

interpreterStackTrace - the stack trace of the new active interpreter

popFromStack

void popFromStack(Expression expression,
                  Interpreter activeInterpreter,
                  InterpreterStackTrace interpreterStackTrace)

Pops expression from the stack. Throws exception if the removed expression is not the expected one. This method should restore the active interpreter and it's stack trace as it was before the expression was pushed to the stack.

Parameters:

expression -

activeInterpreter - the interpreter which will be active after the expression is removed from the stack.

interpreterStackTrace - the stack trace of the active interpreter

getActiveInterpreter

Interpreter getActiveInterpreter()

Gets the active interpreter. This method should return the interpreter used to interpret the expression on the top of the stack.

Returns:

the active interpreter.

getActiveInterpreterStackTrace

InterpreterStackTrace getActiveInterpreterStackTrace()

Gets the active interpreter stack trace. This method should return the interpreter stack trace of the interpreter returned by getActiveInterpreter().

Returns:

the stack trace of the active interpreter
