A piped output stream is the sending end a communications pipe. Two threads can communicate by having one thread send data through a piped output stream (I-§2.16) and having the other thread read the data through a piped input stream.

PipedOutputStream

public PipedOutputStream()

Creates a piped output stream that is not yet connected to a piped input stream. It must be connected to a piped input stream, either by the receiver (I-§2.16.4) or the sender (I-§2.17.4), before being used.

PipedOutputStream

public PipedOutputStream(PipedInputStream  snk)

throws IOException

Creates a piped output stream connected to the specified piped input stream.

Parameters:: snk -The piped input stream to connect to.
Throws: IOException (I-§2.29); If an I/O error occurs.

close

public void close()

throws IOException

Closes this piped output stream and releases any system resources associated with this stream.

Throws: IOException (I-§2.29); If an I/O error occurs.
Overrides:: close in class OutputStream (I-§2.15.2).

connect

public void connect(PipedInputStream  snk)

throws IOException

Connects this piped output stream to a receivier

Parameters:: snk -The piped output stream to connect to.
Throws: IOException (I-§2.29); If an I/O error occurs.

write

public void write(byte  b[], int  off, int  len)

throws IOException

Writes len bytes from the specified byte array starting at offset off to this piped output stream.

Parameters:: b -the data; off -the start offset in the data; len -the number of bytes to write
Throws: IOException (I-§2.29); If an I/O error occurs.
Overrides:: write in class OutputStream (I-§2.15.5).

write

public void write(int  b)

throws IOException

Writes the specified byte to the piped output stream.

Parameters:: b -the byte to be written
Throws: IOException (I-§2.29); If an I/O error occurs.
Overrides:: write in class OutputStream (I-§2.15.6).
