## 24.49 java.io.PipedOutputStream (JDK 1.0)

###

This class is an `OutputStream` that implements one half of a pipe, and is useful for communication between threads. A `PipedOutputStream` must be connected to a `PipedInputStream`, which may be specified when the `PipedOutputStream` is created or with the `connect()` method. Data written to the `PipedOutputStream` are available for reading on the `PipedInputStream`.

See `OutputStream` for information on the low-level methods for writing data to a `PipedOutputStream`. A `FilterOutputStream` may be used to provide a higher-level interface for writing data to a `PipedOutputStream`.

    public class PipedOutputStream extends OutputStream {
        // Public Constructors
                public PipedOutputStream(PipedInputStream snk) throws IOException;
                public PipedOutputStream();
        // Public Instance Methods
                public void close() throws IOException;  // Overrides OutputStream
                public void connect(PipedInputStream snk) throws IOException;
                public synchronized void flush() throws IOException;  // Overrides OutputStream
                public void write(int b) throws IOException;  // Defines OutputStream
                public void write(byte[] b, int off, int len) throws IOException;  // Overrides OutputStream
    }
