Examples of mondrian.calc.Calc.dependsOn()

• mondrian.calc.Calc.dependsOn()
  Returns whether this expression depends upon a given hierarchy.

  If it does not depend on the hierarchy, then re-evaluating the expression with a different member of this context must produce the same answer.

  Some examples:

  • The expression

    [Measures].[Unit Sales]

    depends on all dimensions except [Measures].
  • The boolean expression

    ([Measures].[Unit Sales], [Time].[1997]) > 1000

    depends on all hierarchies except [Measures] and [Time].
  • The list expression

    Filter([Store].[USA].Children, [Measures].[Unit Sales] < 50)

    depends upon all hierarchies except [Store] and [Measures]. How so? Normally the scalar expression would depend upon all hierarchies except [Measures], but the Filter function sets the [Store] context before evaluating the scalar expression, so it is not inherited from the surrounding context.

  @param hierarchy Hierarchy @return Whether this expression's result depends upon the current memberof the hierarchy
