removeStaleAdaptors
public static int removeStaleAdaptors(boolean displayProgress)The reference queue is only processed when a request is made for a weaver adaptor. This means there can be one or two stale weavers left around. If the user knows they have finished all their weaving, they might wish to call removeStaleAdaptors which will process anything left on the reference queue containing adaptorKeys for garbage collected classloaders.- Parameters:
displayProgress
- produce System.err info on the tidying up process- Returns:
- number of stale weavers removed
-
getActiveAdaptorCount
public static int getActiveAdaptorCount()- Returns:
- the number of entries still in the weavingAdaptors map
-
checkQ
public static void checkQ()Process the reference queue that contains stale AdaptorKeys - the keys are put on the queue when their classloader referent is garbage collected and so the associated adaptor (weaver) should be removed from the map -
getNamespace
Returns a namespace based on the contest of the aspects available -
generatedClassesExist
Check to see if any classes have been generated for a particular classes loader. Calls ClassLoaderWeavingAdaptor.generatedClassesExist()- Parameters:
loader
- the class cloder- Returns:
- true if classes have been generated.
