Class ForwardingOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable
    public class ForwardingOutputStream
extends java.io.ByteArrayOutputStream
    This class is a simple output-stream that can be used by a PrintStream to buffer up printed output. When this stream is flushed, it causes the accumulated contents to be sent across an ObjectOutputStream. This allows the underlying ObjectOutputStream to be used both for sending data objects, and strings of printed output.

    • Method Detail

      • flush

        public void flush()
           throws java.io.IOException
        When called, this output stream will convert its accumulated data into a String object, which will then be sent over the underlying object output-stream. Once this is completed, the buffered string data is cleared.
