Interface ConditionEvaluator<T extends BTGConditionModel>

All Known Implementing Classes:

DefaultBTGExpressionEvaluator, IgnoreInvalidatedExpressionEvaluator

public interface ConditionEvaluator<T extends BTGConditionModel>

Generic evaluator for any kind of conditions.

The term 'condition' is used in a very general way as it only specifies that a BTGConditionModel must evaluate into true or false after executing evaluate(BTGConditionModel, UserModel, BTGEvaluationContext)

Method Summary

Modifier and Type	Method and Description
BTGConditionResultModel	checkConditionForUser(UserModel user, BTGConditionModel condition, BTGEvaluationContext context) return last condition evaluation/forced result for user
boolean	evaluate(T condition, UserModel user, BTGEvaluationContext context) Evaluates a BTGConditionModel to true or false.
boolean	invalidateCondition(UserModel user, BTGConditionModel condition, BTGEvaluationContext context) Invalidate latest condition results for given user.
void	setConditionResult(UserModel user, T condition, BTGResultScope resultScope, boolean result, String jaloSessionId, boolean forced) set condition result
