Constructor Summary

Composition(IntegerCODEC f1, IntegerCODEC f2)

Method Summary

void	compress(int[] in, IntWrapper inpos, int inlength, int[] out, IntWrapper outpos) Both inpos and outpos are modified to represent how much data was read and written to if 12 ints (inlength = 12) are compressed to 3 ints, then inpos will be incremented by 12 while outpos will be incremented by 3 we use IntWrapper to pass the values by reference.

compress

public void compress(int[] in,

Description copied from interface: IntegerCODEC

Both inpos and outpos are modified to represent how much data was read and written to if 12 ints (inlength = 12) are compressed to 3 ints, then inpos will be incremented by 12 while outpos will be incremented by 3 we use IntWrapper to pass the values by reference.

                       IntWrapper inpos,
