<h2>PackageDAG</h2>

<p>
    Representation of Package dependencies as directed acyclic graph using a dict (Mapping) as the underlying
    datastructure.
</p>
<p>
    The nodes and their relationships (edges) are internally stored using a map as follows,
</p>
<p>
    {a: [b, c],
     b: [d],
     c: [d, e],
     d: [e],
     e: [],
     f: [b],
     g: [e, f]}
</p>
<p>
    Here, node `a` has 2 children nodes `b` and `c`. Consider edge direction from `a` -> `b` and `a` -> `c`
    respectively.
</p>
<p>
    A node is expected to be an instance of a subclass of `Package`. The keys are must be of class `DistPackage` and
    each item in values must be of class `ReqPackage`. (See also ReversedPackageDAG where the key and value types are
    interchanged).

<a NAME="PackageDAG.get_node_as_parent" ID="PackageDAG.get_node_as_parent"></a>

        Get the node from the keys of the dict representing the DAG.
</p>
<p>
        This method is useful if the dict representing the DAG contains different kind of objects in keys and values.
        Use this method to look up a node obj as a parent (from the keys of the dict) given a node key.
</p>
<p>

<a NAME="PackageDAG.reverse" ID="PackageDAG.reverse"></a>
<h4>PackageDAG.reverse</h4>

</p>
<p>
        In other words, the directions of edges of the nodes in the DAG will be reversed.
</p>
<p>
        Note that this function purely works on the nodes in the graph. This implies that to perform a combination of
        filtering and reversing, the order in which `filter` and `reverse` methods should be applied is important. For
        e.g., if reverse is called on a filtered graph, then only the filtered nodes and it's children will be
        considered when reversing. On the other hand, if filter is called on reversed DAG, then the definition of
        "child" nodes is as per the reversed DAG.
</p>
