Class OracleJDBCTypeFactory

java.lang.Object

org.geolatte.geom.codec.db.oracle.OracleJDBCTypeFactory

All Implemented Interfaces:

java.io.Serializable, SQLTypeFactory

public class OracleJDBCTypeFactory
extends java.lang.Object
implements SQLTypeFactory

Factory for Oracle JDBC extension types (ARRAY, STRUCT, ...).

This factory creates the Oracle extension types using reflection in order to avoid creating compile-time dependencies on the proprietary Oracle driver.
