      • evaluateCachedRight

        public boolean evaluateCachedRight​(org.drools.base.base.ValueResolver valueResolver,
                                   VariableRestriction.VariableContextEntry context,
                                   org.kie.api.runtime.rule.FactHandle left)
        Description copied from interface: MvelEvaluator
        Evaluates the expression using the provided parameters. This method is used when evaluating right-activated beta-constraints, i.e., a fact attribute against a variable value, that is activated from the right. For instance: Person( name == $someName ) This method will be used when a new Person instance is evaluated. So it will cache the value of the "Person" instance and will iterate over the left memory comparing it to each "$someName" bound values.
        Parameters:
        valueResolver - The current working memory
        context - The previously cached context, including the right value and the extractor for the left value.
        left - The left object, from where to extract the bound variable. In the above example, that is the "$someName" variable value.
        Returns:
        Returns true if evaluation is successful. false otherwise.

      • evaluateCachedLeft

        public boolean evaluateCachedLeft​(org.drools.base.base.ValueResolver valueResolver,
                                  VariableRestriction.VariableContextEntry context,
                                  org.kie.api.runtime.rule.FactHandle right)
        Description copied from interface: MvelEvaluator
        Evaluates the expression using the provided parameters. This method is used when evaluating left-activated beta-constraints, i.e., a fact attribute against a variable value, that is activated from the left. For instance: Person( name == $someName ) This method will be used when a new $someName variable is bound. So it will cache the value of $someName and will iterate over the right memory (Person instances) evaluating each occurrence.
        Parameters:
        valueResolver - The current working memory
        context - The previously cached context, including the left value and the extractor for the right value.
        right - The right object, from where to extract the value. In the above example, that is the "Person" instance from where to extract the "name" attribute.
        Returns:
        Returns true if evaluation is successful. false otherwise.
