Based on 9 examples
public class DeflaterOutputStream extends FilterOutputStream
This class implements an output stream filter for compressing data in the "deflate" compression format. It is also used as the basis for other types of compression filters, such as GZIPOutputStream.
Field Summary | |
---|---|
protected byte[] |
buf
Output buffer for writing compressed data. |
protected Deflater |
def
Compressor for this stream. |
Fields inherited from class java.io.FilterOutputStream |
---|
out |
Constructor Summary | |
---|---|
Creates a new output stream with a default compressor and buffer size. |
|
DeflaterOutputStream(OutputStream out, Deflater def) Creates a new output stream with the specified compressor and a default buffer size. |
|
DeflaterOutputStream(OutputStream out, Deflater def, int size) Creates a new output stream with the specified compressor and buffer size. |
Method Summary | |
---|---|
void |
close() Writes remaining compressed data to the output stream and closes the underlying stream. |
protected void |
deflate() Writes next block of compressed data to the output stream. |
void |
finish() Finishes writing compressed data to the output stream without closing the underlying stream. |
void |
write(byte[] b, int off, int len) Writes an array of bytes to the compressed output stream. |
void |
write(int b) Writes a byte to the compressed output stream. |
