public interface DialectFactory extends Service {
	
Builds an appropriate Dialect instance.

If a dialect is explicitly named in the incoming properties, it should used. Otherwise, it is
determined by dialect resolvers based on the passed connection.

An exception is thrown if a dialect was not explicitly set and no resolver could make
the determination from the given connection.
Params:
configValues – The configuration properties.
resolutionInfoSource – Access to DialectResolutionInfo used to resolve the Dialect to use if not
explicitly named
Throws:
HibernateException – No dialect specified and no resolver could make the determination.
Returns:
The appropriate dialect instance./**
