Interface IncrementInstruction

All Superinterfaces:: ClassFileElement, CodeElement, Instruction

public sealed interface IncrementInstruction extends Instruction

Models a local variable increment instruction in the code array of a Code attribute. Corresponding opcodes have a kind of Opcode.Kind.INCREMENT. Delivered as a CodeElement when traversing the elements of a CodeModel.

A local variable increment instruction is composite:

IncrementInstruction(
    int slot,
    int constant
)

where

slot must be within [0, 65535].
constant must be within [-32768, 32767].

See Java Virtual Machine Specification:

6.5.iinc iinc
