        Description copied from interface: OutputByteStream
        Only for internal engineering use. This api can change without notice. Is the current position of this OutputByteStream at or beyond the end of the underlying data.
        Specified by:
        eof in interface OutputByteStream
        Returns:
        True if the current position is beyond the end of the underlying data, false otherwise.
        Throws:

      • toOutputStream

        public SkippingOutputStream toOutputStream()
                                    throws java.io.IOException
        Description copied from interface: OutputByteStream
        This will return a new OutputStream that wraps the same bytes as the OutputByteStream. Writing to or positioning either one will affect the other. This OutputStream may be safely closed without that causing the OutputByteStream to be closed. This is commonly used for external libraries that need an OutputStream. Do NOT use it to pass data around internally as this will generally be inefficient and cause conversion and memory usage.
        Specified by:
        toOutputStream in interface OutputByteStream
        Returns:
        an OutputStream that wraps the same bytes
        Throws:
        java.io.IOException
