Interface CompoundElement<E extends ClassFileElement>

Type Parameters:
E - the member element type
All Superinterfaces:
ClassFileElement, Iterable<E>
All Known Subinterfaces:
ClassModel, CodeAttribute, CodeModel, FieldModel, MethodModel
public sealed interface CompoundElement<E extends ClassFileElement> extends ClassFileElement, Iterable<E> permits ClassModel, CodeModel, FieldModel, MethodModel (not exhaustive)
A class file structure that can be viewed as a composition of its member structures. CompoundElement allows users to traverse these member elements with forEach(Consumer) or elementStream(), or buffer the elements obtained from the traversal through iterator() or elementList().

Unless otherwise specified, all member elements of compatible type will be presented during the traversal if they exist in this element. Some member elements specify that they may appear at most once in this element; if such elements are presented multiple times, the latest occurrence is authentic and all previous occurrences should be ignored.

CompoundElements can be constructed by ClassFileBuilders. ClassFileBuilder.transform(CompoundElement, ClassFileTransform) provides an easy way to create a new structure by selectively processing the original member structures and directing the results to the builder.
