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()

transformSingleValue

@NotNull

 PlusMinusZero valueDestination,
 boolean useNew,
 ExpressionEvaluationContext context,
 String contextDescription,
 Task task,
 OperationResult result)
                                                  throws ExpressionEvaluationException,
ObjectNotFoundException,
SchemaException,
CommunicationException,
ConfigurationException,
SecurityViolationException

Transforms single value tuple.

Parameters:

variables - Variables to be applied. Must not be relativistic! All deltas must be sorted out by now.

valueDestination - Where we are going to put output value(s). Actually it's only supplementary information for the transformer as the actual placement of output values is done in the caller.

useNew - Are we using "new" state of sources/input variables? Again, this is only supplementary information, because the variables should be already non-relativistic. Some scripts need to know the value of "useNew".

context - Caller-specified context of the whole expression evaluation.

Throws:

ExpressionEvaluationException

ObjectNotFoundException

SchemaException

CommunicationException

ConfigurationException

SecurityViolationException
