org.eclipse.steady.java.monitor.trace.SingleStackTraceInstrumentor

All Implemented Interfaces:

IInstrumentor

public class SingleStackTraceInstrumentor
extends AbstractTraceInstrumentor

Tracks how many times a construct has been invoked. Downloads the list of relevant bugs from the backend and collects the stack trace for all their change list elements. Stack traces collected will be transformed into call paths that are again uploaded to the backend.

public SingleStackTraceInstrumentor()

Constructor for SingleStackTraceInstrumentor.

Method Detail

isStacktraceRequestedFor

public boolean isStacktraceRequestedFor(ConstructId _construct)

isStacktraceRequestedFor.

Parameters:

_construct - a ConstructId object.

Returns:

a boolean.

instrument

public void instrument(StringBuffer _code,
                       JavaId _jid,
                       javassist.CtBehavior _behavior,
                       ClassVisitor _cv)
                throws javassist.CannotCompileException

Appends Java source code to the given StringBuffer. After all IInstrumentors appended their respective code, the ensemble will be added to a Construct, which will then be compiled.

Parameters:

_code - a StringBuffer object.

_jid - a JavaId object.

_behavior - a CtBehavior object.

_cv - a ClassVisitor object.

Throws:

javassist.CannotCompileException - if any.
