Detailed Description

The IDeleteImp class is a concrete implementation class for interface IDelete. The IDelete interface defines the FDO Delete command, which deletes instances of a given class that match the specified criteria. Input to the delete command includes the name of the class, and filter criteria by which to identify the instances to be deleted. The filter may be specified either as text or as an expression tree (most likely produced by a query builder). The delete command can delete instances at global scope or instances/values nested within an object collection property. Instances at global scope are referred to simply by the class name. Instances at a nested scope (i.e. instances within a object collection property) are referred to by the containing class name, followed by a '.', followed by the object collection property name.
