Package com.evolveum.midpoint.model.common.expression.evaluator.transformation

Class AbstractValueTransformationExpressionEvaluator<V extends PrismValue,D extends ItemDefinition<?>,E extends TransformExpressionEvaluatorType>

java.lang.Object

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

com.evolveum.midpoint.model.common.expression.evaluator.transformation.AbstractValueTransformationExpressionEvaluator<V,D,E>

Type Parameters:

V - Type of output PrismValues.

D - Definition of output values.

E - Type of the configuration (evaluator) bean.

All Implemented Interfaces:

ExpressionEvaluator<V>

Direct Known Subclasses:

AbstractSearchExpressionEvaluator, ScriptExpressionEvaluator

public abstract class AbstractValueTransformationExpressionEvaluator<V extends PrismValue,D extends ItemDefinition<?>,E extends TransformExpressionEvaluatorType>
extends AbstractExpressionEvaluator<V,D,E>

Evaluates transformational expression: one that transforms input values to output values. Actually, the hard work is delegated to RelativisticEvaluation and AbsoluteEvaluation classes.

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

isIncludeNullInputs

protected boolean isIncludeNullInputs()

isRelative

protected boolean isRelative()

ObjectNotFoundException,
SchemaException,
CommunicationException,
ConfigurationException,
SecurityViolationException

Transforms single value or single values tuple.

Throws:

ExpressionEvaluationException

ObjectNotFoundException
