Interface CompoundElement<E extends ClassFileElement^PREVIEW>

Type Parameters:

E - the element type

All Superinterfaces:

ClassFileElementPREVIEW, Iterable<E>

All Known Subinterfaces:

ClassModelPREVIEW, CodeAttributePREVIEW, CodeModelPREVIEW, FieldModelPREVIEW, MethodModelPREVIEW

CompoundElement is a preview API of the Java platform.

Programs can only use CompoundElement when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.

A ClassFileElement^PREVIEW that has complex structure defined in terms of other classfile elements, such as a method, field, method body, or entire class. When encountering a CompoundElement^PREVIEW, clients have the option to treat the element as a single entity (e.g., an entire method) or to traverse the contents of that element with the methods in this class (e.g., elements(), forEachElement(Consumer), etc.)
