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].
