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. |
Public methods | |
---|---|
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. |

OutputStream : output stream to write the uncompressed data to |
infl |
Inflater : decompressor ("inflater") for this stream |

Public methods
close
public void close ()
Writes any remaining uncompressed data to the output stream and closes the underlying output stream.
Throws | |
---|---|
IOException |
if an I/O error occurs |
finish
public void finish ()
Finishes writing uncompressed data to the output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.
Throws | |
---|---|
IOException |
if an I/O error occurs or this stream is already closed |
flush
public void flush ()
Flushes this output stream, forcing any pending buffered output bytes to be written.
Throws | |
---|---|
IOException |
if an I/O error occurs or this stream is already closed |
write
public void write (byte[] b, int off, int len)
Writes an array of bytes to the uncompressed output stream.
Parameters | |
---|---|
b |
byte : buffer containing compressed data to decompress and write to
the output stream |
off |
int : starting offset of the compressed data within b |
len |
int : number of bytes to decompress from b |
Throws | |
---|---|
IndexOutOfBoundsException |
if off < 0 , or if
len < 0 , or if len > b.length - off |
IOException |
if an I/O error occurs or this stream is already closed |
NullPointerException |
if b is null |
ZipException |
if a compression (ZIP) format error occurs |
write
public void write (int b)
Writes a byte to the uncompressed output stream.
Parameters | |
---|---|
b |
int : a single byte of compressed data to decompress and write to
the output stream |
Throws | |
---|---|
IOException |
if an I/O error occurs or this stream is already closed |
ZipException |
if a compression (ZIP) format error occurs |
