Direct Known Subclasses:

Enclosing class:

CalcProgramBuilder

static class CalcProgramBuilder.InstructionDef
extends Object

Definition for an instruction. An instruction can only do one thing -- add itself to a program -- so this class is basically just a functor. The concrete derived class must provide a name, and implement the add(CalcProgramBuilder, List) method.

Field Summary

Method Summary

(package private) void	add(CalcProgramBuilder builder, CalcProgramBuilder.Operand... operands) Adds this instruction with a set of operands to a program.
(package private) void	add(CalcProgramBuilder builder, CalcReg... regs) Adds this instruction to a program.
(package private) void	add(CalcProgramBuilder builder, List<CalcReg> registers) Convenience method which converts the register list into an array and calls the add(CalcProgramBuilder,CalcReg[]) method.

Method Detail

add

final void add(CalcProgramBuilder builder,
               List<CalcReg> registers)

Convenience method which converts the register list into an array and calls the add(CalcProgramBuilder,CalcReg[]) method.

add

void add(CalcProgramBuilder builder,
         CalcProgramBuilder.Operand... operands)

Adds this instruction with a set of operands to a program.

The default implementation casts each operand to a CalcReg, and calls add(CalcProgramBuilder, CalcReg[]). If this instruction's operands are not registers, override this method.

Parameters:

builder - Program builder

operands - Operands

addInternal

protected final void addInternal(CalcProgramBuilder builder,
                                 CalcProgramBuilder.Operand[] regs)

add

void add(CalcProgramBuilder builder,
         CalcReg... regs)

Adds this instruction to a program.

toString

public String toString()

Overrides:

toString in class Object
