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.

Parameter:

displayProgress - produce System.err info on the tidying up process

Gibt zurück:

number of stale weavers removed

getActiveAdaptorCount

public static int getActiveAdaptorCount()

Gibt zurück:

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

public String getNamespace(ClassLoader loader)

Returns a namespace based on the contest of the aspects available

generatedClassesExist

public boolean generatedClassesExist(ClassLoader loader)

Check to see if any classes have been generated for a particular classes loader. Calls ClassLoaderWeavingAdaptor.generatedClassesExist()

Parameter:

loader - the class cloder

Gibt zurück:

true if classes have been generated.

flushGeneratedClasses

public void flushGeneratedClasses(ClassLoader loader)

prepareForRedefinition

public void prepareForRedefinition(ClassLoader loader,
 String className)

Angegeben von:
