All Implemented Interfaces:

BitField

public class NotView
extends java.lang.Object
implements BitField

Provides a not view for a BitField. See not for more information.

    void sampleCodeNotView(){
        BitSet bs1 = new BitSet();
        bs1.set(0);
        bs1.set(1);

        BitField bf1 = new BitFieldSet(bs1, 5);

        printBitField(bf1, "bf1");

        NotView nv = new NotView(bf1);

        printBitField(nv, " nv");
    }

    void printBitField(BitField bf, String bfName){
        System.out.print(bfName + ": ");
        for(int i = 0; i < bf.maxSize(); i++){
            int j = 0;
            if(bf.get(i))
                j = 1;          
            System.out.print(j);
        }
        System.out.println(""); 
    }

    Output:
        bf1: 11000
         nv: 00111
