Method Detail

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. Accepts every class. Note that the instrumentation involves two levels of filtering: First, DynamicTransformer.transform(ClassLoader, String, Class, java.security.ProtectionDomain, byte[]) filters according to class names, JAR names and JAR directory locations. Second, every IInstrumentor can apply an additional filter in the implementation of this method. Note that

Parameters:

_jid - a JavaId object.

_behavior - a CtBehavior object.

_cv - a ClassVisitor object.

Returns:

a boolean.

merge

public static final Set<ConstructId> merge(Map<String,Set<org.eclipse.steady.shared.json.model.ConstructId>> _map)

Merges the constructs of the map into a single HashSet, i.e., unordered.

Parameters:

_map - a Map object.

Returns:

a Set object.

merge

public static final Set<ConstructId> merge(Map<String,Set<org.eclipse.steady.shared.json.model.ConstructId>> _map,
                                           boolean _ordered)

Merges the constructs of the map into a single set. Returns a TreeSet if _ordered is equal to true, a HashSet otherwise.

Parameters:

_map - a Map object.

_ordered - a boolean.

Returns:

a single set containing all the constructs passed in _map
