Class MemberListCrossJoinArg

java.lang.Object
mondrian.rolap.sql.MemberListCrossJoinArg
All Implemented Interfaces:
CrossJoinArg
public class MemberListCrossJoinArg extends Object implements CrossJoinArg
Represents an enumeration {member1, member2, ...}. All members must to the same level and are non-calculated.

  • Method Details

    • create

      public static CrossJoinArg create(RolapEvaluator evaluator, List<RolapMember> args, boolean restrictMemberTypes, boolean exclude)
      Creates an instance of CrossJoinArg, or returns null if the arguments are invalid. This method also records properties of the member list such as containing calc/non calc members, and containing the All member.

      If restrictMemberTypes is set, then the resulting argument could contain calculated members. The newly created CrossJoinArg is marked appropriately for special handling downstream.

      If restrictMemberTypes is false, then the resulting argument contains non-calculated members of the same level (after filtering out any null members).

      Parameters:
      evaluator - the current evaluator
      args - members in the list
      restrictMemberTypes - whether calculated members are allowed
      exclude - Whether to exclude tuples that match the predicate
      Returns:
      MemberListCrossJoinArg if member list is well formed, null if not.
