-
CRC-32 of uncompressed data.
GZIPOutputStream
public GZIPOutputStream(OutputStream out)
throws IOException
-
Creates a new output stream with a default buffer size.
- Parameters:
out - the output stream- Throws:
IOException - If an I/O error has occurred.
GZIPOutputStream
public GZIPOutputStream(OutputStream out,
int size)
throws IOException
-
Creates a new output stream with the specified buffer size.
- Parameters:
out - the output streamsize - the output buffer size- Throws:
IOException - If an I/O error has occurred.
finish
public void finish()
throws IOException
-
Finishes writing compressed data to the output stream without closing
the underlying stream. Use this method when applying multiple filters
in succession to the same output stream.
- Overrides:
finish in class DeflaterOutputStream- Throws:
IOException - if an I/O error has occurred
write
public synchronized void write(byte[] buf,
int off,
int len)
throws IOException
-
Writes array of bytes to the compressed output stream. This method
will block until all the bytes are written.
- Overrides:
write in class DeflaterOutputStream- Parameters:
buf - the data to be writtenoff - the start offset of the datalen - the length of the data- Throws:
IOException - If an I/O error has occurred.
