      Sets the name of this named set.

    • getType

      Returns the type of this named set.

    • getExp

    • getNameUniqueWithinQuery

      String getNameUniqueWithinQuery()
      Returns a name for this set that is unique within the query.

      This is necessary when there are several 'AS' expressions, or an 'AS' expression overrides a named set defined using 'WITH MEMBER' clause or against a cube.

    • isDynamic

      boolean isDynamic()
      Returns whether this named set is dynamic.

      Evaluation rules:

      • A dynamic set is evaluated each time it is used, and inherits the context in which it is evaluated.
      • A static set is evaluated only on first use, in the base context of the cube.
      Returns:
      Whether this named set is dynamic
