Interface ClassTransform
- All Superinterfaces:
ClassFileTransform<ClassTransform, ClassElement, ClassBuilder>
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

Description copied from interface:ClassFileTransform
Chain this transform with another; elements presented to the builder of this transform will become the input to the next transform.- Specified by:
andThen
in interfaceClassFileTransform<ClassTransform, ClassElement, ClassBuilder>
- Implementation Requirements:
- The default implementation returns this class transform chained with another class transform from the argument. Chaining of two transforms requires to involve a chained builder serving as a target builder for this transform and also as a source of elements for the downstream transform.
- Parameters:
t
- the downstream transform- Returns:
- the chained transform
