Constructor and Description |
---|
DeflaterOutputStream(OutputStream out)
Creates a new DeflaterOutputStream with a default Deflater and
default buffer size.
|
DeflaterOutputStream(OutputStream out,
Deflater defl)
Creates a new DeflaterOutputStream with the given Deflater and
default buffer size.
|
DeflaterOutputStream(OutputStream out,
Deflater defl,
int bufsize)
Creates a new DeflaterOutputStream with the given Deflater and
buffer size.

Modifier and Type | Method and Description |
---|---|
void |
close()
Calls finish () and closes the stream.
|
protected void |
deflate()
Deflates everything in the def's input buffers.
|
void |
finish()
Finishes the stream by calling finish() on the deflater.
|
void |
flush()
Flushes the stream by calling flush() on the deflater and then
on the underlying stream.
|
void |
write(byte[] buf,
int off,
int len)
Writes a len bytes from an array to the compressed stream.
|
void |
write(int bval)
Writes a single byte to the compressed output stream.
