Method Detail

write

public void write(byte[] buf,
                  int off,
                  int len)
           throws IOException

Writes a len bytes from an array to the compressed stream.

Overrides:

write in class DeflaterOutputStream

Parameters:

buf - the byte array.

off - the offset into the byte array where to start.

len - the number of bytes to write.

Throws:

IOException - If an error occurs

close

public void close()
           throws IOException

Writes remaining compressed output data to the output stream and closes it.

Overrides:
