      • bind

        <BoundVar_> Child_ bind​(org.drools.model.Variable<BoundVar_> boundVariable,
                        Function<A,​BoundVar_> bindingFunction)
        Bind a new variable. This call is safe for use outside accumulate() and groupBy(), unlike bind(Variable, Variable, BiFunction) etc.
        Type Parameters:
        BoundVar_ - generic type of the bound variable
        Parameters:
        boundVariable - the new variable
        bindingFunction - the function to apply to create the bound variable
        Returns:
        never null

        <BoundVar_,​LeftJoinVar_> Child_ bind​(org.drools.model.Variable<BoundVar_> boundVariable,
                                           org.drools.model.Variable<LeftJoinVar_> leftJoinVariable,
                                           BiFunction<A,​LeftJoinVar_,​BoundVar_> bindingFunction)
        This must only be used in patterns that will eventually end up in accumulate() or groupBy(). Drools does not support binding 2+ variables outside of accumulate() or groupBy(). Disobeying will result in Drools NullPointerException at runtime.
        Type Parameters:
        BoundVar_ - generic type of the bound variable
        LeftJoinVar_ - generic type of the join variable
        Parameters:
        boundVariable - the new variable
        leftJoinVariable - the variable to use when creating the bound variable
        bindingFunction - the function to apply to create the bound variable
        Returns:
        never null

        As defined by bind(Variable, Variable, BiFunction).
        Type Parameters:
        BoundVar_ - generic type of the bound variable
        LeftJoinVarA_ - generic type of the first join variable
        LeftJoinVarB_ - generic type of the second join variable
        Parameters:
        boundVariable - the new variable
        leftJoinVariableA - the first variable to use when creating the bound variable
        leftJoinVariableB - the second variable to use when creating the bound variable
        bindingFunction - the function to apply to create the bound variable
        Returns:
