<a name="GdaTreeManager.description"></a><h2>Description</h2>
<p>A <a class="link" href="GdaTreeManager.html" title="GdaTreeManager"><span class="type">GdaTreeManager</span></a> object is responsible for creating nodes in the tree(s) for which it
operates.</p>
<p>When creating nodes, a <a class="link" href="GdaTreeManager.html" title="GdaTreeManager"><span class="type">GdaTreeManager</span></a> object can (depending on its implementation), get some
named attributes from the node below which it has to create nodes, using the <a class="link" href="GdaTreeNode.html#gda-tree-node-fetch-attribute" title="gda_tree_node_fetch_attribute ()"><code class="function">gda_tree_node_fetch_attribute()</code></a>
or <a class="link" href="GdaTreeNode.html#gda-tree-node-get-node-attribute" title="gda_tree_node_get_node_attribute ()"><code class="function">gda_tree_node_get_node_attribute()</code></a>. For example the <a class="link" href="GdaTreeMgrColumns.html" title="GdaTreeMgrColumns"><span class="type">GdaTreeMgrColumns</span></a> manager (which creates a node for each column
of a table) needs the table name and the schema in which the table is; both can be specified using an
object's property, or, if not specified that way, are fetched as attributes.</p>
<p>The <a class="link" href="GdaTreeManager.html" title="GdaTreeManager"><span class="type">GdaTreeManager</span></a> itself is an abstract type (which can't be instantiated). Use an existing sub class or subclass
it yourself.</p>
