## org.modeshape.graph
Interface Subgraph

All Superinterfaces:
  Graph.BaseResults<SubgraphNode>, Iterable<SubgraphNode>

    @Immutable
    public interface Subgraph

extends Graph.BaseResults<SubgraphNode>

A subgraph returned by the `Graph`, containing the nodes in the subgraph as well as the properties and children for each of those nodes. The `Iterable.iterator()` method may be used to walk the nodes in the subgraph in a pre-order traversal.

Since this subgraph has a single `node that is the top of the subgraph`, the methods that take a String path or `path object` will accept absolute or relative paths.

This subgraph will not contain any `nodes` that exist below the `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.

Method Summary
`Location` | `getLocation()` Get the location of the subgraph, which is the location of the node at the top of the subgraph.
`int` | `getMaximumDepth()` Get the maximum depth requested for this subgraph.
`SubgraphNode` | `getNode(Name relativePath)` Get the node at the supplied location.
`SubgraphNode` | `getRoot()` Get the node that is at the `root` of the subgraph.

Method Detail

### getLocation

    Location getLocation()

  Get the location of the subgraph, which is the location of the node at the top of the subgraph.

  Returns:
    the location of the top node in the subgraph; never null

### getMaximumDepth

    int getMaximumDepth()

  Get the maximum depth requested for this subgraph. The actual subgraph may not be as deep, but will never be deeper than this value.

  Returns:
    the maximum depth requested; always positive

### getNode

    SubgraphNode getNode(Name relativePath)

  Get the node at the supplied location.

  Parameters:
    `relativePath` - the name that makes up a relative path to the node that is an immediate child of the `root`
  Returns:
    the node, or null if the node is not `included` in these results

### getRoot

    SubgraphNode getRoot()

  Get the node that is at the `root` of the subgraph.

  Returns:
    the root node in the subgraph
