Runnable passed to the PlSqlWrapper to process the ResultSet and/or
CallableStatement during execution. The processing is done via a separate
class so that any work done on the database is managed appropriately (i.e.
not on the event thread), and it also allows the wrapper framework to
correctly close the Statement and ResultSet when done.
public void prepareCall(java.sql.CallableStatement cs)
Called once the statement has been created, but before execution so that
any output parameters can be registered. Input parameters are processed
automatically assuming they were passed to the PlSqlWrapper constructor.
