public class InflaterOutputStream extends FilterOutputStream
Implements an output stream filter for uncompressing data stored in the "deflate" compression format.
InflaterInputStream
, DeflaterInputStream
, DeflaterOutputStream
protected final Inflater inf
Decompressor for this stream.
protected final byte[] buf
Output buffer for writing uncompressed data.
public InflaterOutputStream(OutputStream out)
Creates a new output stream with a default decompressor and buffer size.
out
- output stream to write the uncompressed data toNullPointerException
- if out
is nullpublic InflaterOutputStream(OutputStream out, Inflater infl)
Creates a new output stream with the specified decompressor and a default buffer size.
out
- output stream to write the uncompressed data toinfl
- decompressor ("inflater") for this streamNullPointerException
- if out
or infl
is nullpublic InflaterOutputStream(OutputStream out, Inflater infl, int bufLen)
Creates a new output stream with the specified decompressor and buffer size.

- if bufLen <= 0
NullPointerException
- if out
or infl
is nullpublic void close() throws IOException
Writes any remaining uncompressed data to the output stream and closes the underlying output stream.

public void flush() throws IOException
Flushes this output stream, forcing any pending buffered output bytes to be written.

IOException
- if an I/O error occurs or this stream is already closedFilterOutputStream.out
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.
IOException
- if an I/O error occurs or this stream is already closedpublic void write(int b) throws IOException
Writes a byte to the uncompressed output stream.

Writes an array of bytes to the uncompressed output stream.
