All Known Subinterfaces:
DiscontinuedInstruction.JsrInstruction, DiscontinuedInstruction.RetInstruction
public sealed interface DiscontinuedInstruction extends Instruction permits DiscontinuedInstruction.JsrInstruction, DiscontinuedInstruction.RetInstruction
Marker interface for instruction discontinued from the code array of a Code attribute. Delivered as a CodeElement when traversing the elements of a CodeModel.
API Note:
While most instructions have convenience factory methods in CodeBuilder, discontinued instructions can only be supplied to code builders explicitly with CodeBuilder::with to discourage their use.
