Method Detail

matches

public static boolean matches(byte[] signature,
                              int length)

Checks if the signature matches what is expected for a Unix compress file.

Parameters:

signature - the bytes to check

length - the number of bytes to check

Returns:

true, if this stream is a Unix compress compressed stream, false otherwise
