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 where:
aconst_null and iconst_0. An intrinsic constant instruction is composite:
IntrinsicConstantInstruction(Opcode opcode)
opcode- Must be of the constant kind and have a fixed size of 1.
