com.evolveum.midpoint.repo.common.expression.evaluator.LiteralExpressionEvaluator<V,D>

All Implemented Interfaces:

ExpressionEvaluator<V>

public class LiteralExpressionEvaluator<V extends PrismValue,D extends ItemDefinition<?>>
extends AbstractExpressionEvaluator<V,D,Collection<javax.xml.bind.JAXBElement<?>>>

Always returns zero set with literal value (values) specified in the evaluator. Plus and minus sets are empty. Note: using evaluatorElements as "expressionEvaluatorBean" is a bit strange. It is because I am too lazy to find more appropriate name for the field. Moreover, for all other uses it really _is_ the expression evaluator bean. So leaving fixing this to the future. [pmed]

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

CommunicationException

ConfigurationException

shortDebugDump

public String shortDebugDump()

Description copied from interface: ExpressionEvaluator

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