java.util.zip
Class InflaterOutputStream

java.lang.Object
 extended by java.io.OutputStream
 extended by java.io.FilterOutputStream
 extended by java.util.zip.InflaterOutputStream

All Implemented Interfaces:

Closeable, Flushable

---

public class InflaterOutputStream
extends FilterOutputStream

Implements an output stream filter for uncompressing data stored in the "deflate" compression format.

Since:

1.6

See Also:

InflaterInputStream, DeflaterInputStream, DeflaterOutputStream

---

Field Summary
protected byte[]	buf Output buffer for writing uncompressed data.
protected Inflater	inf Decompressor for this stream.

Fields inherited from class java.io.FilterOutputStream
out

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.

Field Detail

inf

protected final Inflater inf

Decompressor for this stream.

---

buf

protected final byte[] buf

Output buffer for writing uncompressed data.

Constructor Detail

InflaterOutputStream

public InflaterOutputStream(OutputStream out)

Creates a new output stream with a default decompressor and buffer size.

Parameters:

out - output stream to write the uncompressed data to

Throws:

NullPointerException - if out is null

---

InflaterOutputStream

public InflaterOutputStream(OutputStream out,
 Inflater infl)

Creates a new output stream with the specified decompressor and a default buffer size.

Parameters:

out - output stream to write the uncompressed data to

infl - decompressor ("inflater") for this stream

Throws:

NullPointerException - if out or infl is null

---

InflaterOutputStream

public InflaterOutputStream(OutputStream out,
 Inflater infl,
 int bufLen)

Creates a new output stream with the specified decompressor and buffer size.

Parameters:

out - output stream to write the uncompressed data to

infl - decompressor ("inflater") for this stream

bufLen - decompression buffer size

Throws:

IllegalArgumentException - if bufLen is <= 0

NullPointerException - if out or infl is null

Method Detail

close

public void close()
 throws IOException

Writes any remaining uncompressed data to the output stream and closes the underlying output stream.

Specified by:

close in interface Closeable

Overrides:

close in class FilterOutputStream

Throws:

IOException - if an I/O error occurs

See Also:

FilterOutputStream.flush(), FilterOutputStream.out

---

flush

public void flush()
 throws IOException

Flushes this output stream, forcing any pending buffered output bytes to be written.

Specified by:

flush in interface Flushable

Overrides:

flush in class FilterOutputStream

Throws:

IOException - if an I/O error occurs or this stream is already closed

See Also:

FilterOutputStream.out

---

finish

public void finish()
 throws IOException

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

---

write

public void write(int b)
 throws IOException

Writes a byte to the uncompressed output stream.

Overrides:

write in class FilterOutputStream

Parameters:

b - 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

---

write

public void write(byte[] b,
 int off,
 int len)
 throws IOException

Writes an array of bytes to the uncompressed output stream.

Overrides:

write in class FilterOutputStream

Parameters:

b - buffer containing compressed data to decompress and write to the output stream

off - starting offset of the compressed data within b

len - 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

See Also:

FilterOutputStream.write(int)
