Class VariationsFactory

java.lang.Object

org.openl.rules.variation.VariationsFactory

public abstract class VariationsFactory
extends Object

Factory for simple variations creation. In most cases there will be created JXPathVariation instead of situations when VariationsFactory.THIS_POINTER used as the path to field to be modified(in such a case ArgumentReplacementVariation will be created). As an additional feature there is possibility to use deep cloning in variations.

Method Detail

getVariation

public static Variation getVariation(String vairationId,
                                     int argumentIndex,
                                     String path,
                                     Object valueToSet)

Creates variation using all needed parameters.

Parameters:

vairationId - Id for variation.

argumentIndex - Index of argument to be modified.

path - Path to field that will be modified. Or VariationsFactory.THIS_POINTER for argument replacemnt variation.

valueToSet - Value to set for modified field.

Returns:

Variation that corresponds the specified path.

getVariation

public static Variation getVariation(String vairationId,
                                     int argumentIndex,
                                     String path,
                                     Object valueToSet,
                                     boolean cloneArguments)

Creates variation using all needed parameters with possibility to use cloning for variations.

Parameters:

vairationId - Id for variation.

argumentIndex - Index of argument to be modified.

path - Path to field that will be modified. Or VariationsFactory.THIS_POINTER for argument replacemnt variation.

valueToSet - Value to set for modified field.

cloneArguments - Flag that determines whether the created variation should be wrapped by DeepCloningVariation.

Returns:

Variation that corresponds the specified path.
