Method Detail

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.

upladInformation

public void upladInformation(AbstractGoal _exe,
                             int _batch_size)

Saves the information that has been collected by the instrumentor in the context of the given AbstractGoal.

Parameters:

_exe - a AbstractGoal object.

_batch_size - a int.

awaitUpload

public void awaitUpload()

Make the current thread wait until the upload of the information finished.

getStatistics

public Map<String,Long> getStatistics()

Return instrumentor-specific statistics.

Returns:

a Map object.

acceptToInstrument

public boolean acceptToInstrument(JavaId _jid,
                                  javassist.CtBehavior _behavior,
                                  ClassVisitor _cv)

Returns true of a given instrumentor accepts to instrument the given Java class, false otherwise.

Parameters:

_jid - a JavaId object.

_behavior - a CtBehavior object.

_cv - a ClassVisitor object.

Returns:

a boolean.
