AcMapQueryUnit class

Header file: MapQuery.h.

A query unit represents either a query condition or a subordinate query branch. It is sometimes referred to as a query node or a query operand.

Every query unit contains a = 4) BSPSPopupOnMouseOver(event);;">join operator which is used to combine query units logically. The join operator of the first query unit within a query branch is ignored.

Changes to a query unit affect the query only after a call to the AcMapQuery::Define function.

The AcMapQueryBranch and AcMapQueryCondition classes are derived from the AcMapQueryUnit class.

Do not subclass from this class.
