public PipedWriter(PipedReader snk) throws IOException
snk.
snk - The piped reader to connect to.
IOException - if an I/O error occurs.public PipedWriter()
| Method Detail |
|---|
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)
snk - the piped reader to connect to.
IOException - if an I/O error occurs.public void write(int c) throws IOException
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.
c - the char to be written.
IOException - if the pipe is
broken,
unconnected, closed
or an I/O error occurs.public void write(char[] cbuf, int off, int len) throws IOException
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.
cbuf - the data.off - the start offset in the data.len - the number of characters to write.
IOException - if the pipe is
broken,
unconnected, closed
or an I/O error occurs.public void flush() throws IOException
IOException - if the pipe is closed, or an I/O error occurs.public void close() throws IOException
IOException - if an I/O error occurs.
