All Implemented Interfaces:

ExpressionEvaluator<V>

public class ScriptExpressionEvaluator<V extends PrismValue,D extends ItemDefinition<?>>
extends AbstractValueTransformationExpressionEvaluator<V,D,ScriptExpressionEvaluatorType>

Executes specified script written e.g. in Groovy, JavaScript, Python, etc. Apache Velocity template language is supported as well, It is a part of Expression and ExpressionEvaluator framework. This class is a bridge between the "relativity" and "script execution" aspects of the script expression evaluation: . ScriptExpression evaluates scripts and ignores all those complex aspects of expressions' relativity, . and AbstractValueTransformationExpressionEvaluator and the super-classes deal with relativity handling (etc) and ignore technical aspects of running Groovy/JS/whatever scripts.

Method Details

checkEvaluatorProfile

protected void checkEvaluatorProfile(ExpressionEvaluationContext context)

Description copied from class: AbstractExpressionEvaluator

Check expression profile. Throws security exception if the execution is not allowed by the profile.

This implementation works only for simple evaluators that do not have any profile settings. Complex evaluators should override this method.

Overrides:

checkEvaluatorProfile in class AbstractExpressionEvaluator<V extends PrismValue,D extends ItemDefinition<?>,ScriptExpressionEvaluatorType>

transformSingleValue

@NotNull
protected @NotNull List<V> transformSingleValue(@NotNull
 @NotNull ValueTransformationContext vtCtx,
 @NotNull
 @NotNull OperationResult result)
                                         throws ExpressionEvaluationException,
ObjectNotFoundException,
SchemaException,
CommunicationException,
ConfigurationException,
SecurityViolationException

Description copied from class: AbstractValueTransformationExpressionEvaluator

Transforms single value or single values tuple.

Specified by:

transformSingleValue in class AbstractValueTransformationExpressionEvaluator<V extends PrismValue,D extends ItemDefinition<?>,ScriptExpressionEvaluatorType>

Throws:

ExpressionEvaluationException

ObjectNotFoundException

SchemaException

CommunicationException

ConfigurationException

SecurityViolationException

shortDebugDump

public String shortDebugDump()

Description copied from interface: ExpressionEvaluator

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