returns whether this object allows attachment 
<p>
Some <a class="el" href="class_buffered_transformation.html">BufferedTransformation</a> objects (e.g. <a class="el" href="class_filter.html">Filter</a> objects) allow other <a class="el" href="class_buffered_transformation.html">BufferedTransformation</a> objects to be attached. When this is done, the first object instead of buffering its output, sents that output to the attached object as input. The entire attachment chain is deleted when the anchor object is destructed.

<dl compact><dt><b>Note:</b></dt><dd>Hard flushes must be used with care. It means try to process and output everything, even if there may not be enough data to complete the action. For example, hard flushing a <a class="el" href="class_hex_decoder.html">HexDecoder</a> would cause an error if you do it after inputing an odd number of hex encoded characters. For some types of filters, for example <a class="el" href="class_zlib_decompressor.html">ZlibDecompressor</a>, hard flushes can only be done at "synchronization points". These synchronization points are positions in the data stream that are created by hard flushes on the corresponding reverse filters, in this example <a class="el" href="class_zlib_compressor.html">ZlibCompressor</a>. This is useful when zlib compressed data is moved across a network in packets and compression state is preserved across packets, as in the ssh2 protocol.</dd></dl>
