Filters are pruning the graph by keeping only nodes and edges that satisify filters conditions. Filters are predicates or functions that reduce the graph and therefore create sub-graphs.

Filters are the basic building blocks that are wrapped in queries and assembled to make simple or complex conditions on nodes and edges.

Filters objects are built in {@link FilterBuilder}. Implementors should define their own FilterBuilder class to propose new filter to users. @author Mathieu Bastian @see Query

            HierarchicalGraph hgraph = (HierarchicalGraph) graph;
            Filter filter = filters[0];
            if (filter instanceof NodeFilter && ((NodeFilter) filter).init(hgraph)) {
                List<Node> nodeToRemove = new ArrayList<Node>();
