PipedInputStream(PipedOutputStream)

Creates an input file given a PiledOutputStream.

PipedInputStream()

Creates an input file that isn't connected to anything (yet).

close()

Closes the input stream.

connect(PipedOutputStream)

Connect this input stream to a sender.

read()

Reads a byte.

read(byte[], int, int)

Reads into an array of bytes.

  public PipedInputStream(PipedOutputStream src)

Creates an input file given a PiledOutputStream.

Parameters:

stream - the stream to connect to.

PipedInputStream

  public PipedInputStream()

Creates an input file that isn't connected to anything (yet). It must be connected to a PipedOutputStream before being used.

  public void connect(PipedOutputStream src)

Connect this input stream to a sender.

Parameters:

src - The OutpueStream to connect to.

read

  public synchronized int read()

Reads a byte. Will block if no input is available.

Returns:

the byte read, or -1 if the end of the stream is reached.

Overrides:

read in class InputStream

read

  public synchronized int read(byte b[],
                               int off,
                               int len)

Reads into an array of bytes. Blocks until some input is available. For efficiency,this method should be overridden in a subclass (the default implementation reads 1 byte at a time).

Parameters:

b - the buffer into which the data is read

off - the start offset of the data

len - the maximum number of bytes read

Returns:

the actual number of bytes read, -1 is returned when the end of the stream is reached.

Throws: IOException

i/o error occurred

Overrides:

read in class InputStream

close

  public void close()

Closes the input stream. Must be called to release any resources associated with the stream.

Throws: IOException

i/o error occurred

Overrides:

close in class InputStream
