This class is for parameters that may expand to multiple values. Such is the case for parameters
specified in the 'IN' clause of a query. For example, a query may have the following form:
SELECT * FROM Products
WHERE ProductID IN (:pids)
The parameter 'pids' may have one or more values.
Implementation Notes:
This interface implements the IQueryInParam interface and inherits the 'getValue' and 'setValue'
methods. These methods should be implemented to set and retrieve the first value only. Do not use
these methods to set and retrieve the entire vector, instead use the 'getValues' and 'setValues'
methods from this interface.
