Method Detail

doTraceValueChanges

protected boolean doTraceValueChanges()

doTraceErrors

protected boolean doTraceErrors()

doTraceEnteringExiting

protected boolean doTraceEnteringExiting()

doTraceReturning

protected boolean doTraceReturning()

doCaptureTimeouts

protected boolean doCaptureTimeouts(Method model)

translate

public void translate(Method model)

After instrumentation, the method will have a structure like one presented here: GW.enteringStatement(...) try { ... original method body ... GW.returning(...) } catch (Throwable t) { GW.onError(...); } finally { GW.exitingStatement(...) }

Specified by:

translate in interface Translator<Method>

Parameters:

model - - method that will be instrumented

traceEnteringExiting

protected void traceEnteringExiting(Method model)

traceReturn

protected void traceReturn(Method model)

traceTimeout

protected void traceTimeout(Method model)

traceErrors

protected void traceErrors(Method model)

traceValueChanges

protected void traceValueChanges(Method model)

Destructive procedure that modifies the method body to contain a 'change' event signal after each assignment operator. The new assigned value and the right-hand-side receiver name are sent to the runtime component. Assignment tracking is done after the assignment expression executed successfully.

Parameters:

model - - method representation that gets modified

transformConstructor

protected void transformConstructor(Method model)

transformToBlockConstructs

protected void transformToBlockConstructs(Method model)

isMethodExcluded

protected boolean isMethodExcluded(Method model)

getJavac

protected JavaCompiler getJavac()

getHelper

protected JavaCompilerHelper getHelper()
