Method

intdecompress(byte src[], int src_off, int src_len, byte dst[], int dst_off, int dst_len)
decompress 
int len;
int bptr;
int iptr = src_off;
int optr = dst_off;
len = unsign(src[iptr++]);
if (len > 17) {
    len = len - 17;
    do {
...
Stringdecompress(byte[] compressed, int sequenceLen)
decompress 
byte[] byteArr = new byte[sequenceLen];
int curRead = 0;
for (int i = 0; i < compressed.length; i++) {
    byte bits = compressed[i];
    byte a = (byte) ((bits >> 6) & 0x3);
    byte b = (byte) ((bits >> 4) & 0x3);
    byte c = (byte) ((bits >> 2) & 0x3);
    byte d = (byte) (bits & 0x3);
...
Stringdecompress(byte[] in, int len)
Uncompresses the compressed data ( in ) with the length ( len ) and returns the uncompressed String . 
byte[] out = new byte[4096];
int outPos = 0;
int carry = -1;
for (int i = 0; i < len * 2; i++) {
    int tblPos = in[i / 2] >> 4 - 4 * (i % 2) & 0xF;
    if (carry == -1) {
        if (tblPos < 13) {
            out[outPos++] = (byte) FREQUENCY_ORDERED_CHARS[tblPos];
...
intdecompress_action(byte[] source)
Main process of decompression with Linear Prediction 
int numbits = 8;
int i = 0;
int value = 0;
if (source.length <= 20) {
    return 2;
for (i = 0; i < numbits; i++) {
    if (((source[20]) & (1 << i)) == 1) {
...
StringdecompressHuffman(byte[] message, int length)
Unpacks huffman encoded text. 
try {
    int charsDecoded = 0;
    int keyIndex = 0;
    StringBuilder sb = new StringBuilder();
    for (int offset = 0; true; offset++) {
        byte character = message[offset];
        if (character >= 0) {
            keyIndex++;
...
byte[]decompressRTF(byte[] src)
Decompresses compressed-RTF data. 
byte[] dst; 
int in = 0; 
int out = 0; 
if (src == null || src.length < 16) {
    throw new IllegalArgumentException("Invalid compressed-RTF header");
int compressedSize = (int) getU32(src, in);
in += 4;
