matches
public static boolean matches(byte[] signature, int length)
Checks if the signature matches what is expected for a zlib / deflated file with the zlib header.- Parameters:
signature
- the bytes to checklength
- the number of bytes to check- Returns:
- true, if this stream is zlib / deflate compressed with a header stream, false otherwise
