Method Detail

evaluate

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

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

getElementName

QName getElementName()

Fully qualified name of the element defining the expression (e.g. c:path).

shortDebugDump

String shortDebugDump()

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