Constructor Summary | |
---|---|
InflaterOutputStream(OutputStream out)
Creates a new output stream with a default decompressor and buffer size. |
|
InflaterOutputStream(OutputStream out,
Inflater infl)
Creates a new output stream with the specified decompressor and a default buffer size. |
|
InflaterOutputStream(OutputStream out,
Inflater infl,
int bufLen)
Creates a new output stream with the specified decompressor and buffer size. |
Method Summary | |
---|---|
void |
close()
Writes any remaining uncompressed data to the output stream and closes the underlying output stream. |
void |
finish()
Finishes writing uncompressed data to the output stream without closing the underlying stream. |
void |
flush()
Flushes this output stream, forcing any pending buffered output bytes to be written. |
void |
write(byte[] b,
int off,
int len)
Writes an array of bytes to the uncompressed output stream. |
void |
write(int b)
Writes a byte to the uncompressed output stream. |
