Class PipedWriter
- Appendable, Closeable, Flushable
This class writes its chars to a
PipedReader to
which it is connected.
It is highly recommended that a
PipedWriter and its
connected
PipedReader be in different threads. If
they are in the same thread, read and write operations could deadlock
the thread.
void | close()- This method closes this stream so that no more data can be written
to it.
|
void | connect(PipedReader sink)- Connects this object to the specified
PipedReader
object.
|
void | flush()- This method does nothing.
|
void | write(char[] buffer, int offset, int len)- This method writes
len chars of data from the char array
buf starting at index offset in the array
to the stream.
|
void | write(int b)- Write a single char of date to the stream.

PipedWriter
public PipedWriter()
Create an unconnected PipedWriter. It must be connected
to a PipedReader using the connect
method prior to writing any data or an exception will be thrown.
PipedWriter
public PipedWriter(PipedReader sink)
throws IOException Create a new PipedWriter instance
to write to the specified PipedReader. This stream
is then ready for writing.
sink - The PipedReader to connect this stream to.
IOException - If sink has already been connected
to a different PipedWriter.
close
public void close()
throws IOException This method closes this stream so that no more data can be written
to it. Any further attempts to write to this stream may throw an
exception
- close in interface Closeable
- close in interface Writer
connect
public void connect(PipedReader sink)
throws IOException Connects this object to the specified PipedReader
object. This stream will then be ready for writing.
sink - The PipedReader to connect this stream to
IOException - If the stream has not been connected or has
been closed.
write
public void write(char[] buffer,
int offset,
int len)
throws IOException This method writes len chars of data from the char array
buf starting at index offset in the array
to the stream. Note that this method will block if the
PipedReader to which this object is connected has
a buffer that cannot hold all of the chars to be written.
- write in interface Writer
buffer - The array containing chars to write to the stream.offset - The index into the array to start writing chars from.len - The number of chars to write.
IOException - If the stream has not been connected or has
been closed.
write
public void write(int b)
throws IOException Write a single char of date to the stream. Note that this method will
block if the PipedReader to which this object is
connected has a full buffer.
- write in interface Writer
b - The char of data to be written, passed as an int.
IOException - If the stream has not been connected or has
been closed.
