public interface ObjectGraph

extends Persistable, Walker, ObjectGraphNode, GraphModel

Provides a top-level abstraction of an object graph. More specifically this abstraction represents an instance-based view of related persistable objects that form an associative structure. The object graph acts as the overall container where it references the root (node) object of the structure of related objects. From the root node the structure of the object graph can span outwards and can consequently be traversed.

The object graph is composed of nodes and edges. Each node has an association to another node that is represented as an edge, which maintains the association. An edge can be either unidirectional or bidirectional. An unidirectional edge represents a type of object reference. A bidirectional edge represents a type of link.
