  • 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 <= 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

    Specified by:

    close in interface AutoCloseable

    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
