• BufferedStreamFeeder

  public BufferedStreamFeeder(InputStream is)

• BufferedStreamFeeder

  public BufferedStreamFeeder(InputStream is,
                      int bufsize)

Method Detail

• getStream

  public InputStream getStream()

  Returns inputstream

  Returns:

  Input Stream from which bytes are read

• feed

  public int feed(IBytesConsumer consumer)

  Feeds bytes to the consumer
  Returns bytes actually consumed
  This should return 0 only if the stream is EOF or the consumer is done

• feed

  public int feed(IBytesConsumer consumer,
         int maxbytes)

  Feeds the consumer (with at most maxbytes)
  This should return 0 only if the stream is EOF or the consumer is done

• feedFixed

  public boolean feedFixed(IBytesConsumer consumer,
                  int nbytes)

  Feeds exactly nbytes, retrying if necessary

  Parameters:

  consumer - Consumer

  nbytes - Number of bytes

  Returns:

  true if success, false otherwise (EOF on stream, or consumer is done)

• refillBuffer

  protected void refillBuffer()

  If there are not pending bytes to be consumed tries to fill the buffer with bytes from the stream.

• hasMoreToFeed

  public boolean hasMoreToFeed()

  Returuns true if we have more data to fed the consumer. This internally tries to grabs more bytes from the stream if necessary

• setCloseStream

  public void setCloseStream(boolean closeStream)

  Parameters:

  closeStream - If true, the underlying stream will be closed on when close() is called

• close

  public void close()

  Closes this object. Sets EOF=true, and closes the stream if closeStream is true This can be called internally, or from outside. Idempotent, secure, never throws exception.

• setInputStream

  public void setInputStream(InputStream is)

  Sets a new underlying inputstream. This allows to reuse this object. The old underlying is not closed and the state is not reset (you should call close() previously if you want that)

  Parameters:

  is -

• isEof

  public boolean isEof()

  Returns:

  EOF on stream, or close() was called

• setFailIfNoFeed

  public void setFailIfNoFeed(boolean failIfNoFeed)

  If this flag is set (default: false), any call to feed() that returns zero (no byte feed) will throw an exception. This is useful to be sure of avoid infinite loops in some scenarios.

  Parameters:

  failIfNoFeed -
