Examples of org.jboss.dna.graph.Subgraph

org.jboss.dna.graph.Subgraph
A subgraph returned by the {@link Graph}, containing the nodes in the subgraph as well as the properties and children for each of those nodes. The {@link #iterator()} method may be used to walk the nodes in the subgraph in a pre-order traversal.
Since this subgraph has a single {@link #getLocation() node that is the top of the subgraph}, the methods that take a String path or {@link Path path object} will accept absolute or relative paths.

This subgraph will not contain any {@link #iterator() nodes} that exist below the {@link #getMaximumDepth() maximum depth}. Also, all nodes included in the subgraph have all their properties and children. However, nodes that are at the maximum depth of the subgraph will contain the locations for child nodes that are below the maximum depth and therefore not included in this subgraph.
