24.48 java.io.PipedInputStream (JDK 1.0)

This class is an InputStream that implements one-half of a pipe, and is useful for communication between threads. A PipedInputStream must be connected to a PipedOutputStream object, which may be specified when the PipedInputStream is created or with the connect() method. Data read from a PipedInputStream object are received from the PipedOutputStream to which it is connected.

See InputStream for information on the low-level methods for reading data from a PipedInputStream. A FilterInputStream may be used to provide a higher-level interface for reading data from a PipedInputStream.


public class PipedInputStream extends InputStream {

    // Public Constructors

            public PipedInputStream(PipedOutputStream src) throws IOException;

            public PipedInputStream();

    // Constants

        1.1  protected static final int PIPE_SIZE;

    // Protected Instance Variables

        1.1  protected byte[] buffer;

        1.1  protected int in;

        1.1  protected int out;

    // Public Instance Methods

            public synchronized int available() throws IOException;  // Overrides InputStream

            public void close() throws IOException;  // Overrides InputStream

            public void connect(PipedOutputStream src) throws IOException;

            public synchronized int read() throws IOException;  // Defines InputStream

            public synchronized int read(byte[] b, int off, int len) throws IOException;  // Overrides InputStream

    // Protected Instance Methods

        1.1  protected synchronized void receive(int b) throws IOException;

}
