Package org.sqlproc.engine.jdbc.type

Class JdbcTypeFactory

java.lang.Object
org.sqlproc.engine.jdbc.type.JdbcTypeFactory
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.
