Interface SqlTypeValue

All Known Subinterfaces:: DisposableSqlTypeValue

All Known Implementing Classes:: AbstractSqlTypeValue, SqlLobValue

public interface SqlTypeValue

Interface to be implemented for setting values for more complex database specific types not supported by the standard setObject method.

Implementations perform the actual work of setting the actual values. They must implement the callback method setTypeValue which can throw SQLExceptions that will be caught and translated by the calling code. This callback method has access to the underlying Connection via the given PreparedStatement object, if that should be needed to create any database-specific objects.

Since:: 1.1
