class is not a part of the public API. The writer operates on string-qvariant pairs. QVariant values can be associated with string keys. Several operations are supported - adding, replacing and inserting. Those operations differ in how they handle existing keys with same name.<p> +The writer automatically cloes the filesystem resource on destruction but can be also closed manually. Writing to a closed writer has no effect. <hr><h2>Constructor & Destructor Documentation</h2> +<a class="anchor" name="e40a943a3cf86d6ca9b5350357d83a74"></a><!-- doxytag: member="CDBWriter::CDBWriter"
