Method Detail
insert
public void insert(Object obj)
throws SQLException
update
public void update(Object obj)
throws SQLException
getList
public Vector getList()
throws SQLException
This represents the "shallow retrieve." That is, the ability to return
just the ID and Name of an object. Useful for browsing, or for pick
lists. (A technique to avoid a deep retrieve of all objects,
fully-formed, which could be quite expensive in terms of performance
and using potentially scarce DBMS resources.)
save
public void save(Object obj)
throws SQLException
getData
getAll
public Vector getAll()
throws SQLException
Return all objects.
