Interface SqlTypeFactory

All Known Implementing Classes:

JdbcTypeFactory, SqlComposedTypeFactory

public interface SqlTypeFactory

The factory definition, which can be used to construct the SqlMetaType instances. In the process of the META SQL statements and mapping rules parsing the input/output values META types have to be established. For this purpose a factory class responsible for these META types construction has to be supplied.
The implementation depends the stack on top of which the SQL Processor works. It can be a singleton or a registry.
