java.lang.classfile.instruction

public sealed Interface OperatorInstruction

Known Direct Implementers: jdk.internal.classfile.impl.AbstractInstruction.UnboundOperatorInstruction
Imports: java.lang.classfile.CodeElement, .CodeModel, .Instruction, .Opcode, .TypeKind, jdk.internal.classfile.impl.AbstractInstruction, .Util

Models an arithmetic operator instruction in the code array of a Code attribute. Corresponding opcodes have a kind of Opcode.Kind#OPERATOR. Delivered as a CodeElement when traversing the elements of a CodeModel.

An operator instruction is composite:

OperatorInstruction(Opcode opcode)

Since: 24
See Also: Opcode.Kind#OPERATOR
