Enclosing class:

IntervalSet

public static class IntervalSet.ByteIntervals
extends java.lang.Object

Allows you to keep int and long intervals in the same location. Lets you know how many bytes are needed to represent the set of ranges.

        try{

            IntervalSet set = new IntervalSet();

            set.add(Range.createRange(55, 58));
            set.add(Range.createRange(90, 97));
            set.add(Range.createRange(3, 7));
            set.add(Range.createRange(52, 53));
            set.add(Range.createRange(28, 33));
            set.add(Range.createRange(60, 73));

            IntervalSet.ByteIntervals asByte = set.toBytes();

            System.out.println("Length of set = " + set.getSize() 
            + " and interval as a list " + set.getAllIntervalsAsList() );     

            //A length of zero means there haven't been any longs added to the set yet.
            System.out.println("Length of asByte's long =" + asByte.longs.length);

            //create a long range
            set.add(Range.createRange(0xFFFFFFFFF0l, 0xFFFFFFFFFFl));
            asByte = set.toBytes();
            System.out.println("New length of asByte's long =" 
                                + asByte.longs.length);

            System.out.println("Length of asByte=" + asByte.length() );

            //Now there will be one one long range from 
            //3 until 0xFFFFFFFFFFl (size: 10)
            set.add(Range.createRange(3, 0xFFFFFFFFFFl));
            asByte = set.toBytes();

            System.out.println("Length of set= " + set.getSize() 
            + " and interval as a list " + set.getAllIntervalsAsList() );

            System.out.println("Length of asByte=" + asByte.length() );

        }
        catch(Exception e){
            e.printStackTrace();
        }
        Output:
            Length of set = 39 and interval as a list [3-7, 28-33, 52-53, 55-58, 60-73, 90-97]
            Length of asByte's long =0
            New length of asByte's long =10
            Length of asByte=58
            Length of set= 1099511627773 and interval as a list [3-1099511627775]
            Length of asByte=10
