Interface InvokeInstruction

All Superinterfaces:
ClassFileElement, CodeElement, Instruction
public sealed interface InvokeInstruction extends Instruction
Models a method invocation instruction in the code array of a Code attribute, other than invokedynamic. Corresponding opcodes will have a kind of Opcode.Kind.INVOKE. Delivered as a CodeElement when traversing the elements of a CodeModel.
