com.evolveum.midpoint.model.impl.expr.SequentialValueExpressionEvaluator<V,D>

All Implemented Interfaces:

ExpressionEvaluator<V>

public class SequentialValueExpressionEvaluator<V extends PrismValue,D extends ItemDefinition>
extends AbstractExpressionEvaluator<V,D,SequentialValueExpressionEvaluatorType>

Returns current value of a given sequence object. The value is returned in the zero set. Plus and minus sets are empty. The value for a given sequence OID is stored in the model context, so it is returned each time this evaluator (with given sequence OID) is invoked.

Description copied from interface: ExpressionEvaluator

Executes the evaluation in a given context. The context provides necessary data, evaluator provides definition of processing that should be carried out.

Returns:

Result of the evaluation in the form of delta set triple (i.e. added, deleted, unchanged values).

Throws:

SchemaException

ExpressionEvaluationException

ObjectNotFoundException

SecurityViolationException

shortDebugDump

public String shortDebugDump()

Description copied from interface: ExpressionEvaluator

Short characterization of the evaluator. One line, often only a single word.
