public class PipedWriter extends Writer
| Constructor and Description | 
|---|
| PipedWriter()Creates a piped writer that is not yet connected to a
 piped reader. | 
| PipedWriter(PipedReader snk)Creates a piped writer connected to the specified piped
 reader. | 
| Modifier and Type | Method and Description | 
|---|---|
| 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(char[] cbuf,
     int off,
     int len)Writes  lencharacters from the specified character array
 starting at offsetoffto this piped output stream. | 
| void | write(int c)Writes the specified  charto the piped output stream. | 
public PipedWriter(PipedReader snk) throws IOException
snk.snk - The piped reader to connect to.IOException - if an I/O error occurs.public PipedWriter()
public void connect(PipedReader snk) throws IOException
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:
 
or the call:src.connect(snk)
The two calls have the same effect.snk.connect(src)

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.

 This method blocks until all the characters are written to the output
 stream.
