public class DirectReadQuery extends DataReadQuery
Purpose: Concrete class to perform a direct read.
Responsibilities: Used in conjunction with DirectCollectionMapping. This can be used to read a single column of data (i.e. one field). A container (implementing Collection) of the data values is returned.
