Query package.
Class | Description |

Predicate | Base class for native queries. |
Interface | Description |
---|---|
ICandidate | candidate for Db4objects.Db4o.Query.IEvaluation callbacks. During query execution all registered Db4objects.Db4o.Query.IEvaluation callback handlers are called with Db4objects.Db4o.Query.ICandidate proxies that represent the persistent objects that meet all other Db4objects.Db4o.Query.IQuery criteria. A Db4objects.Db4o.Query.ICandidate provides access to the persistent object it represents and allows to specify, whether it is to be included in the Db4objects.Db4o.IObjectSet resultset. |
IConstraint | constraint to limit the objects returned upon query execution . Constraints are constructed by calling Query.constrain() . Constraints can be joined with the methods Db4objects.Db4o.Query.IConstraint.And and Db4objects.Db4o.Query.IConstraint.Or . The methods to modify the constraint evaluation algorithm may be merged, to construct combined evaluation rules. Examples:
|
IConstraints | set of Db4objects.Db4o.Query.IConstraint objects. This extension of the Db4objects.Db4o.Query.IConstraint interface allows setting the evaluation mode of all contained Db4objects.Db4o.Query.IConstraint objects with single calls. See also Db4objects.Db4o.Query.IQuery.Constraints . |
IEvaluation | for implementation of callback evaluations. |
IQuery | handle to a node in a S.O.D.A. |
IQueryComparator | Comparator for sorting queries on JDKs where java.util.Comparator is not available. |
