Java compact1, compact2, compact3 java.util.zip Class InflaterOutputStream（JDK8）

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 <= 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
