Package org.harctoolbox.irp

Class BitField

java.lang.Object

org.harctoolbox.irp.IrpObject

org.harctoolbox.irp.BitField

All Implemented Interfaces:

Serializable, EquationSolving, Numerical, XmlExport

Direct Known Subclasses:

FiniteBitField, InfiniteBitField

public abstract class BitField
extends IrpObject
implements Numerical, EquationSolving

This class implements Bitfields as described in Chapter 5, except for that it does not know how to transform itself into a bitstream -- that is what the class BitStream does. Accordingly, it does not know bit directions.

• BitStream
• Serialized Form
