This operator removes facts from a result of a LogicalOlapOp that does not comply with a condition. We assume a LEAN Data Cube (i.e., dataset with observations on the lowest levels only).
DiceOp gets as input an input operator, a List<Node[]> list with a header and hierarchies according to Olap4ld_Metadata#getHierarchies.28.29 to be diced (as a signature) and a List<List<Node[]>> list of list. Each list describes one possible combination of level members. Each member list contains with a header and members according to Olap4ld_Metadata#getMembers.28.29.
- See RollupOp#Problem:_How_to_rollup_in_Linked_Data.3F for solution regarding rollup.
