Examples of org.h2.compress.Compressor.expand()

org.h2.compress.Compressor.expand()
Expand a number of compressed bytes. @param in the compressed data @param inPos the offset at the input array @param inLen the number of bytes to read @param out the output area @param outPos the offset at the output array @param outLen the size of the uncompressed data

            byte[] result = new byte[pageSize];
            long time = System.currentTimeMillis();
            for (int i = 0; i < 1000; i++) {
                for (int k = 0; k < comp.size(); k++) {
                    byte[] data = comp.get(k);
                    compress.expand(data, 0, data.length, result, 0, pageSize);
