Interface Instruction

All Known Subinterfaces:

Instruction.AddNodeInstruction, Instruction.CopyNodeInstruction, Instruction.MoveNodeInstruction, Instruction.RemoveNodeInstruction, Instruction.SetPropertyInstruction

All Known Implementing Classes:

AddNodeInstructionImpl, BaseInstruction, CopyNodeInstructionImpl, MoveNodeInstructionImpl, RemoveNodeInstructionImpl, SetPropertyInstructionImpl

public interface Instruction

FIXME - Remove other interfaces and renamed AddNodeInstructionImpl into AddNodeInstruction etc. An Instruction is an abstraction of a single JSOP operation.

Each operation is a concrete sub-interface of Instruction and extending it by the specific properties of the operation. There is no exact 1 : 1 mapping between a JSOP operation and a sub-interface, i.e. in JSOP there is one add operation for adding nodes and properties whereas there are two specific sub-interfaces; one for adding a node and one for adding a property.
