Interface CodeTransform
- All Superinterfaces:
- ClassFileTransform<CodeTransform, CodeElement, CodeBuilder>
- Functional Interface:
- This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface
public non-sealed interface CodeTransform
extends ClassFileTransform<CodeTransform, CodeElement, CodeBuilder>
A transformation on streams of 
CodeElement.  The stream can come
 from a CodeModel, or a handler to a CodeBuilder as in
 CodeBuilder.transforming(java.lang.classfile.CodeTransform, java.util.function.Consumer<java.lang.classfile.CodeBuilder>).
 
 Refer to ClassFileTransform for general guidance and caution around
 the use of transforms for structures in the class file format.
 
 A code transform can be lifted to a method or a class transform via MethodTransform.transformingCode(CodeTransform) and ClassTransform.transformingMethodBodies(CodeTransform), transforming only
 the CodeModel within those structures and passing all other elements
 to the builders.

- finisher- the function to call when transformation is complete
- Returns:

andThenDescription copied from interface:ClassFileTransformChain this transform with another; elements presented to the builder of this transform will become the input to the next transform.This method is implemented by the Class-File API. Users usually don't have sufficient access to Class-File API functionalities to override this method correctly for generic downstream transforms. - Specified by:
- andThenin interface- ClassFileTransform<CodeTransform, CodeElement, CodeBuilder>
- Implementation Requirements:
- The default implementation returns this code transform chained with another code 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
