public class ValueReadQuery extends DirectReadQuery
Purpose: Concrete class to perform a read of a single data value.
Responsibilities: Used in conjunction with CursoredStream size and Platform getSequence. This can be used to read a single data value (i.e. one field). A single data value is returned, or null if no rows are returned.
