Interface ConstantInstruction.IntrinsicConstantInstruction

All Superinterfaces:

ClassFileElement, CodeElement, ConstantInstruction, Instruction

Enclosing interface:

ConstantInstruction

public static sealed interface ConstantInstruction.IntrinsicConstantInstruction
extends ConstantInstruction

Models an "intrinsic constant" instruction, which encodes the constant value in its opcode. Examples include aconst_null and iconst_0.

An intrinsic constant instruction is composite:

IntrinsicConstantInstruction(Opcode opcode)

where:

opcode

Must be of the constant kind and have a fixed size of 1.

Since:

24
