Interface ReturnInstruction

All Superinterfaces:: ClassFileElement, CodeElement, Instruction

public sealed interface ReturnInstruction extends Instruction

Models a return-from-method instruction in the code array of a Code attribute. Corresponding opcodes have a kind of Opcode.Kind.RETURN. Delivered as a CodeElement when traversing the elements of a CodeModel.

A return-from-method instruction is composite:

ReturnInstruction(TypeKind typeKind)

where typeKind is computational or void.

Since:
