Constructor Details

ClassLoaderWeavingAdaptor

public ClassLoaderWeavingAdaptor()

ClassLoaderWeavingAdaptor

@Deprecated
public ClassLoaderWeavingAdaptor(ClassLoader deprecatedLoader,
 IWeavingContext deprecatedContext)

Deprecated.

We don't need a reference to the class loader and using it during construction can cause problems with recursion. It also makes sense to supply the weaving context during initialization to.

Method Details

initialize

public void initialize(ClassLoader classLoader,
 IWeavingContext context)

lint

protected void lint(String name,
 String[] infos)

getContextId

public String getContextId()

Specified by:

getContextId in interface IMessageContext

Overrides:

getContextId in class WeavingAdaptor

accept

protected boolean accept(String className,
 byte[] bytes)

Determine whether a type should be accepted for weaving, by checking it against any includes/excludes.

Overrides:

accept in class WeavingAdaptor

Parameters:

className - the name of the type to possibly accept

bytes - the bytecode for the type (in case we need to look inside, eg. annotations)

Returns:

true if it should be accepted for weaving

shouldDump

protected boolean shouldDump(String className,
 boolean before)

Overrides:

shouldDump in class WeavingAdaptor

getDumpDir

protected String getDumpDir()

Overrides:

getDumpDir in class WeavingAdaptor

Returns:

the directory in which to dump - default is _ajdump but it

getNamespace

public String getNamespace()

Returns:

Returns the key.

generatedClassesExistFor

public boolean generatedClassesExistFor(String className)

Check to see if any classes are stored in the generated classes cache. Then flush the cache if it is not empty

Parameters:

className - TODO

Returns:

true if a class has been generated and is stored in the cache

flushGeneratedClasses

public void flushGeneratedClasses()

Flush the generated classes cache

flushGeneratedClassesFor

public void flushGeneratedClassesFor(String className)

Remove generated classes based on the supplied className. This will remove any entries related to this name - so the class itself plus and inner classes.

Parameters:

className - a slashed classname (e.g. com/foo/Bar)

createMethodHandle

public static MethodHandle createMethodHandle(String className,
 String methodName,
 Class<?>... argumentTypes)
                                       throws ClassNotFoundException,

createMethodHandle

IllegalAccessException

createMethodHandle

public static MethodHandle createMethodHandle(Method method,
 boolean setAccessible)
                                       throws IllegalAccessException

Throws:

IllegalAccessException

defineClass
