Interface Interfaces

All Superinterfaces:

ClassElement, ClassFileElement

public sealed interface Interfaces
extends ClassElement

Models the interfaces (JVMS 4.1) of a class. An Interfaces appears at most once in a ClassModel: if it does not appear, the class has no interfaces, which is equivalent to an Interfaces whose interfaces() returns an empty list. A ClassBuilder sets the interfaces to an empty list if the interfaces is not supplied.
