InstructionFactory

Factory class for creating an instruction by its opcode and instruction index inside a Code attribute.

Static Method Summary

Static Public Methods
public static	of(methodInfo: MethodInfo, idx: Number, opcode: Number, wide: Boolean): AbstractInstruction Creates instructions based on pre-defined configurations allowing the complex process of building instructions to be simplified into a 3 parameter method.

Constructor Summary

Private Constructor
private	constructor(methodInfo: MethodInfo, idx: Number, opcode: Number, wide: Boolean)

Member Summary

Private Members
private	idx: Number
private	instruction: AbstractInstruction
private get	isWide: Boolean: * Flag for if the instruction is wide.
private	methodInfo: MethodInfo
private	opcode: Number
private get	shouldWrap: Boolean: * Flag for if the instruction should be wrapped by an InstructionWrapper object.
private	wide: Boolean
private get	wrapType: InstructionWrapper \| null: * Gets the type of wrapper that should be applied when creating the instruction.

Method Summary

Private Methods
private	build(): AbstractInstruction Creates an instance of the instruction and wraps it with an InstructionWrapper if necessary.
