public final class LazyClassGen
extends Object

Lazy lazy lazy. We don't unpack the underlying class unless necessary. Things like new methods and annotations accumulate in here until they must be written out, don't add them to the underlying MethodGen! Things are slightly different if this represents an Aspect.

getAjcPreClinit

public LazyMethodGen getAjcPreClinit()

Retrieve the ajc$preClinit method - this method captures any initialization AspectJ wants to ensure happens in a class. It is called from the static initializer. Maintaining this separation enables overweaving to ignore join points added due to earlier weaves. If the ajc$preClinit method cannot be found, it is created and a call to it is placed in the real static initializer (the call is placed at the start of the static initializer).

Returns:

the LazyMethodGen representing the ajc$ clinit

createExtendedAjcPreClinit

public LazyMethodGen createExtendedAjcPreClinit(LazyMethodGen previousPreClinit,
 int i)

factory method for building multiple extended clinit methods. Constructs a new clinit method that invokes the previous one and then returns it. The index is used as a name suffix.

Parameters:

previousPreClinit -

i -

getAnnotationCachingField

public Field getAnnotationCachingField(BcelShadow shadow,
 ResolvedType toType,
 boolean isWithin)

Create a field in the type containing the shadow where the annotation retrieved during binding can be stored - for later fast access.

Parameters:

shadow - the shadow at which the @annotation result is being cached

Returns:

a field
