메소드	설명
CreateQuery ( ClassMapping mapping, DaoCriteria crit ) : IDaQuery	Builds the query based on a serializable criteria. The Query object is particular to the implementation, but may contain things like the parameters parsed out, or whatever makes sense to this FastDaoLayer. You can think of this method as a method to convert from the generic DaoCriteria into the specific details necessary for querying.
DisposeOfQuery ( IDaQuery query ) : void	Should be called when you're done with the query. Allows us to cache the objects for reuse.

protected UnqueryableDaLayer ( IConnectionDescriptor connDesc, bool supportsNumRecords ) : Azavea.Open.DAO.Criteria
connDesc	IConnectionDescriptor	The connection descriptor that is being used by this FastDaoLayer.
supportsNumRecords	bool	If true, methods that return numbers of records affected will be /// returning accurate numbers. If false, they will probably return /// FastDAO.UNKNOWN_NUM_ROWS.
