  net.sf.farrago.fennel.calc.CalcReg

All Implemented Interfaces:

CalcProgramBuilder.Operand

public class CalcReg
extends Object
implements CalcProgramBuilder.Operand

Represents a virtual register. Each register lives in a register set of type CalcProgramBuilder.RegisterSetType
Each register is of type CalcProgramBuilder.OpType

Constructor Detail

CalcReg

CalcReg(CalcProgramBuilder.OpType opType,
        Object value,
        CalcProgramBuilder.RegisterSetType registerType,
        int storageBytes,
        int index)

Method Detail

getOpType

public final CalcProgramBuilder.OpType getOpType()

getRegisterType

final CalcProgramBuilder.RegisterSetType getRegisterType()

getIndex

final int getIndex()

getValue

final Object getValue()

printValue

void printValue(PrintWriter writer,
                boolean outputComments)

Serializes the value in the virtual register if not null
NOTE See also print(java.io.PrintWriter) which serializes the "identity" of the register

Parameters:

writer -

outputComments -

print

public final void print(PrintWriter writer)

Serializes the identity of the register. It does not attempt to serialize its value; see printValue(java.io.PrintWriter, boolean) for that.

Specified by:

print in interface CalcProgramBuilder.Operand

Parameters:

writer -
