Annotation Type Instruction

@Repeatable(value=Instruction.Instructions.class)
 @Target(value={METHOD,CONSTRUCTOR})
public @interface Instruction

Used to mark a method to be replaced with an OpCode and its operand. The method can then be used in a smart contract. A method can be annotated with multiple Instructions, which offers the possibility to create a short, static script that is inserted wherever the annotated method is called.

The method's body is ignored by the NeoVM compiler if it has this annotation.
