Detailed Description

The ISelectImp class is a concrete implementation of interface ISelect. The ISelect interface defines the Select command, which queries for features of a given class that match the specified criteria. Input to the select command includes the name of the class, the list of properties to be returned, and a filter. All but the class name is optional. If the list of properties to be returned is empty then all properties are returned. The filter may be specified either as text or as an expression tree (most likely produced by a query builder). The result of executing a select command is an IFeatureReader reference (see "Reading Features"). If the feature provider supports locking, then the select command can optionally lock all of the features selected, via the ExecuteWithLock method (see "Locking Commands" for more information on locking features).
