Hi Ian,
Work hasn't started yet on the TypeProviders. The general idea, however, is
to provide an SPI of this form (actual API may vary completely):
package org.jooq;
import java.sql.CallableStatement;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLInput;
import java.sql.SQLOutput;
public interface TypeProvider<T> {
String sql (TypeProviderContext ctx, T value);
void register(TypeProviderContext ctx, CallableStatement cs, int
parameterIndex);
void set (TypeProviderContext ctx, PreparedStatement stmt, T
value);
void set (TypeProviderContext ctx, SQLOutput o, T value);
T get (TypeProviderContext ctx, ResultSet rs, int columnIndex);
T get (TypeProviderContext ctx, CallableStatement cs, int
parameterIndex);
T get (TypeProviderContext ctx, SQLInput i);
}
Unlike the current Converters, there is no notion of actual data type
conversion in this SPI, and thus no <U> and <T> type. Instead, jOOQ will
call this SPI to implement pretty much all interaction with JDBC. You can
then bind your implementation on any column, e.g. on TIMESTAMPTZ columns,
and extend jOOQ completely transparently.
There will also be a DefaultTypeProvider that implements all the existing
functionality that is spread across org.jooq.impl.Val, org.jooq.impl.Utils,
org.jooq.impl.DefaultBindContext, and other types.
Hope this helps,
Lukas
