Classes:

• Query: handle to a query graph and reference to a specific node. The query graph consists of multiple nodes, each representing a class or a member of a class. The structure can be linked in any way that the class model used allows. A Query object references a single node of this graph. The graph can be traversed with the functions descendant() and parent() which return references to other nodes of the graph. These two functions will automatically extend the graph, if necessary. execute() evaluates the entire graph against the objects stored in the data container. execute() can be called from any node ...
• Constraint: constraint for a single query node. A Constraint is associated with one single Query node - a single member of a class. Constraints are constructed by calling Query.constrain() . Constraints can be joined with the methods and() and or(). The following mutual exclusive functions set the evaluation mode. The subsequent call prevails: identity(), equal(), greater(), greaterOrEqual(), smaller(), smallerOrEqual(), like(), contains() is(), and not() are also mutually exclusive.
• ObjectContainer: database engine interface. The ObjectContainer interface provides all functions to store, retrieve and delete objects and to change object state.
• ObjectSet: query resultset. The ObjectSet interface providedes iterator functions to navigate through a set of objects retrieved by a query.
