From class


    java.io.Writer

Public constructors
`PipedWriter(PipedReader snk)` Creates a piped writer connected to the specified piped reader.
`PipedWriter()` Creates a piped writer that is not yet connected to a piped reader.

Public methods
`void`	`close()` Closes this piped output stream and releases any system resources associated with this stream.
`void`	`connect(PipedReader snk)` Connects this piped writer to a receiver.
`void`	`flush()` Flushes this output stream and forces any buffered output characters to be written out.
`void`	`write(int c)` Writes the specified `char` to the piped output stream.
`void`	`write(char[] cbuf, int off, int len)` Writes `len` characters from the specified character array starting at offset `off` to this piped output stream.

    java.io.Writer

`Writer`	`append(char c)` Appends the specified character to this writer.
`Writer`	`append(CharSequence csq, int start, int end)` Appends a subsequence of the specified character sequence to this writer.
`Writer`	`append(CharSequence csq)` Appends the specified character sequence to this writer.
`abstract void`	`close()` Closes the stream, flushing it first.
`abstract void`	`flush()` Flushes the stream.
`void`	`write(String str)` Writes a string.
`void`	`write(int c)` Writes a single character.
`void`	`write(String str, int off, int len)` Writes a portion of a string.
`abstract void`	`write(char[] cbuf, int off, int len)` Writes a portion of an array of characters.
`void`	`write(char[] cbuf)` Writes an array of characters.

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

PipedWriter

Added in API level 1

PipedWriter (PipedReader snk)

Creates a piped writer connected to the specified piped reader. Data characters written to this stream will then be available as input from snk.

Parameters
`snk`	`PipedReader`: The piped reader to connect to.

Throws
`IOException`	if an I/O error occurs.

PipedWriter

Added in API level 1

PipedWriter ()

Creates a piped writer that is not yet connected to a piped reader. It must be connected to a piped reader, either by the receiver or the sender, before being used.

See also:

Public methods

close

Added in API level 1

void close ()

Closes this piped output stream and releases any system resources associated with this stream. This stream may no longer be used for writing characters.

Throws
`IOException`	if an I/O error occurs.

connect

Added in API level 1

void connect (PipedReader snk)

Connects this piped writer to a receiver. If this object is already connected to some other piped reader, an IOException is thrown.

If snk is an unconnected piped reader and src is an unconnected piped writer, they may be connected by either the call:

 src.connect(snk)

or the call:

 snk.connect(src)

The two calls have the same effect.

Parameters
`snk`	`PipedReader`: the piped reader to connect to.

Throws
`IOException`	if an I/O error occurs.

flush

Added in API level 1

void flush ()

Flushes this output stream and forces any buffered output characters to be written out. This will notify any readers that characters are waiting in the pipe.

Throws
`IOException`	if the pipe is closed, or an I/O error occurs.

write

Added in API level 1

void write (int c)

Writes the specified char to the piped output stream. If a thread was reading data characters from the connected piped input stream, but the thread is no longer alive, then an IOException is thrown.

Implements the write method of Writer.

Parameters
`c`	`int`: the `char` to be written.

Throws
`IOException`	if the pipe is `broken`, `unconnected`, closed or an I/O error occurs.

write

Added in API level 1

void write (char[] cbuf, 
                int off, 
                int len)

Writes len characters from the specified character array starting at offset off to this piped output stream. This method blocks until all the characters are written to the output stream. If a thread was reading data characters from the connected piped input stream, but the thread is no longer alive, then an IOException is thrown.

Parameters
`cbuf`	`char`: the data.
`off`	`int`: the start offset in the data.
`len`	`int`: the number of characters to write.

Throws
`IOException`	if the pipe is `broken`, `unconnected`, closed or an I/O error occurs.
