Java Utililty Methods Byte Array Decompress

int decompress(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 {
...

String decompress(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);
...

String decompress(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];
...

int decompress_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) {
...

String decompressHuffman(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;
