<dl class="note" 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" title="Decode base 16 data back to bytes.">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" title="ZLIB Decompressor (RFC 1950).">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" title="ZLIB Compressor (RFC 1950).">ZlibCompressor</a>. This is useful when zlib compressed data is moved across a network
