Java.io.PipedOutputStream Class

Introduction

The Java.io.PipedOutputStream class is a piped output stream that can be connected to a piped input stream to create a communications pipe.Following are the important points about PipedOutputStream −

The piped output stream is the sending end of the pipe.

Attempting to use both objects from a single thread is not recommended as it may deadlock the thread.

Data is written to a PipedOutputStream object by one thread and data is read from the connected PipedInputStream by some other thread.

The pipe is said to be broken if a thread that was reading data bytes from the connected piped input stream is no longer apve.

Class constructors

Sr.No.	Constructor & Description
1	PipedOutputStream() This creates a piped output stream that is not yet connected to a piped input stream.
2	PipedOutputStream(PipedInputStream snk) This creates a piped output stream connected to the specified piped input stream.

Sr.No.

Constructor & Description

PipedOutputStream()

This creates a piped output stream that is not yet connected to a piped input stream.

PipedOutputStream(PipedInputStream snk)

This creates a piped output stream connected to the specified piped input stream.

Class methods

Sr.No.	Method & Description
1	void close() This method closes this piped output stream and releases any system resources associated with this stream.
2	void connect(PipedInputStream snk) This method connects this piped output stream to a receiver.
3	void flush() This method flushes this output stream and forces any buffered output bytes to be written out.
4	void write(byte[] b, int off, int len) This method writes len bytes from the specified byte array starting at offset off to this piped output stream.
5	void write(int b) This method writes the specified byte to the piped output stream.
