All Implemented Interfaces:

SqlTypeFactory
```
public class JdbcTypeFactory
extends Object
implements SqlTypeFactory
```
The factory definition for the JDBC stack, 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 is based on the Singleton design pattern.
