Method Detail

inflate

public static byte[] inflate(byte[] txtbyte)
                      throws java.lang.Exception

Inflates a compressed buffer.

Parameters:

txtbyte -

Returns:

the uncompressed byte array or null if the buffer is too small

inflate

public static byte[] inflate(byte[] txtbyte,
                             int factor)
                      throws java.lang.Exception

Inflates a compressed buffer.

Parameters:

txtbyte - compressed byte array

factor - estimated compression factor - guich@504_3: ignored

Returns:

the uncompressed byte array or null if the buffer is too small

deflate

public static byte[] deflate(byte[] txtbyte,
                             int compressionLevel)
                      throws java.lang.Exception

Deflate an uncompressed buffer.

Parameters:

txtbyte - byte array to compress

compressionLevel - values are 0 (no compression), 1 (min compression) to 9 (max compression)

Returns:

the compressed byte array
