<h1>com::mxgraph::mxGraphModel Class Reference</h1><!-- doxytag: class="com::mxgraph::mxGraphModel" --><!-- doxytag: inherits="com::mxgraph::mxIGraphModel" -->
<p>Implements a graph model. The graph model acts as a wrapper around the cells which are in charge of storing the actual graph datastructure. The model acts as a transactional wrapper with event notification for all changes, whereas the cells contain the atomic operations for updating the actual datastructure.

<p>Merges the children of the given cell into the given target cell inside this model. All cells are cloned unless there is a corresponding cell in the model with the same id, in which case the source cell is ignored and all edges are connected to the corresponding cell in this model. Edges are considered to have no identity and are always cloned unless the cloneAllEdges flag is set to false, in which case edges with the same id in the target model are reconnected to reflect the terminals of the source edges. </p>
<p>Clones the children of the source cell into the given target cell in this model and adds an entry to the mapping that maps from the source cell to the target cell with the same id or the clone of the source cell that was inserted into this model. </p>
