Field Summary

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

Inherited Field Summary

From class java.io.FilterOutputStream

protected OutputStream

out

The underlying output stream to be filtered.

Public 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.

Public 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.

Inherited Method Summary

From class java.io.FilterOutputStream

void	close() Closes this output stream and releases any system resources associated with the stream.
void	flush() Flushes this output stream and forces any buffered output bytes to be written out to the stream.
void	write(byte[] b) Writes b.length bytes to this output stream.
void	write(byte[] b, int off, int len) Writes len bytes from the specified byte array starting at offset off to this output stream.
void	write(int b) Writes the specified byte to this output stream.

From class java.io.OutputStream

void	close() Closes this output stream and releases any system resources associated with this stream.
void	flush() Flushes this output stream and forces any buffered output bytes to be written out.
void	write(byte[] b) Writes b.length bytes from the specified byte array to this output stream.
void	write(byte[] b, int off, int len) Writes len bytes from the specified byte array starting at offset off to this output stream.
abstract void	write(int b) Writes the specified byte to this output stream.

From class java.lang.Object

Object	clone() Creates and returns a copy of this Object.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of Class that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.

From interface java.io.Closeable

Public Constructors

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

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

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

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

out	output stream to write the uncompressed data to
infl	decompressor ("inflater") for this stream
bufLen	decompression buffer size

Public Methods

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

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

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

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

Writes an array of bytes to the uncompressed output stream.

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

public void write (int b)

Writes a byte to the uncompressed output stream.

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
