Class RolapHierarchy.LimitedRollupMember

    • Method Detail

      • getExpression

        public Exp getExpression()
        Description copied from class: MemberBase
        Returns the expression by which this member is calculated. The expression is not null if and only if the member is not calculated.
        Specified by:
        getExpression in interface Member
        Overrides:
        getExpression in class RolapCubeMember

      • isCalculated

        public boolean isCalculated()
        Description copied from interface: Member
        Returns whether this member is computed using either a with member clause in an mdx query or a calculated member defined in cube.
        Specified by:
        isCalculated in interface Member
        Overrides:
        isCalculated in class DelegatingRolapMember

      • isEvaluated

        public boolean isEvaluated()
        Description copied from interface: Member
        Returns whether this member should be evaluated within the Evaluator.

        Normally Member.isCalculated() and Member.isEvaluated() should return the same value, but in situations where mondrian would like to treat the two concepts separately such in role based security, these values may differ.

        Specified by:
        isEvaluated in interface Member
        Overrides:
        isEvaluated in class DelegatingRolapMember
        Returns:
        true if evaluated

      • setContextIn

        public abstract void setContextIn​(RolapEvaluator evaluator)
        Pushes this calculated member or tuple onto the stack of evaluation contexts, and sets the context to the default member of the hierarchy.
        Parameters:
        evaluator - Evaluator

      • getSolveOrder

        public abstract int getSolveOrder()
        Returns the solve order of this calculation. Identifies which order calculations are expanded.
        Returns:
        Solve order

      • getHierarchyOrdinal

        public abstract int getHierarchyOrdinal()
        Returns the ordinal of this calculation; to resolve ties.
        Returns:
        Ordinal or calculation

      • isCalculatedInQuery

        public abstract boolean isCalculatedInQuery()
        Returns whether this calculation is a member is computed from a WITH MEMBER clause in an MDX query.
        Returns:
        whether this calculation is computed in an MDX query

      • getCompiledExpression

        public abstract Calc getCompiledExpression​(mondrian.rolap.RolapEvaluatorRoot root)
        Returns the compiled expression to evaluate the scalar value of the current cell. This method will be called frequently, so the implementation should probably compile once and cache the result.
        Parameters:
        root - Root evaluation context
        Returns:
        Compiled scalar expression

      • containsAggregateFunction

        public abstract boolean containsAggregateFunction()
        Returns whether this calculation contains an aggregate function.
        Returns:
        Whether this calculation contains an aggregate function.
