Class FunctionExpressionEvaluator<V extends PrismValue,D extends ItemDefinition<?>>

com.evolveum.midpoint.model.common.expression.evaluator.FunctionExpressionEvaluator<V,D>

All Implemented Interfaces:

ExpressionEvaluator<V>

public class FunctionExpressionEvaluator<V extends PrismValue,D extends ItemDefinition<?>>
extends AbstractExpressionEvaluator<V,D,FunctionExpressionEvaluatorType>

Calls specified library function expression. It is something like a macro: Arguments for the function call (expression themselves) are evaluated into triples, which become additional sources for the function expression. Then the function expression is evaluated and the output triple is returned as an output triple for the function expression evaluation. FIXME there are not triples in the current implementation! Only plain values. Somewhat similar to (script-callable) LibraryFunctionExecutor.

evaluate

public PrismValueDeltaSetTriple<V> evaluate(ExpressionEvaluationContext context,
 OperationResult parentResult)
                                     throws SchemaException,
ExpressionEvaluationException,
ObjectNotFoundException,
CommunicationException,
ConfigurationException,
SecurityViolationException

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

CommunicationException

ConfigurationException

SecurityViolationException

shortDebugDump

public String shortDebugDump()

Description copied from interface: ExpressionEvaluator

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