Header file: MapQuery.h.

The AcMapQueryBranch class is derived from the AcMapQueryUnit class. It is used by the AcMapQuery::Define to build or modify a query definition.

You get an AcMapQueryBranch pointer using the new operator and you are responsible for deleting the allocated memory using the delete operator.

A query branch is a tree constructed of one or more query units. Each query unit in the query branch can be either a subordinate query branch or an instance of one of the following condition classes: AcMapLocationCondition, AcMapSQLCondition, AcMapDataCondition, and AcMapPropertyCondition. The conditions, which hang off the query branch, describe the query’s selection criteria. Structurally, a condition is a simple node in the query branch.

Do not subclass from this class.
