java.lang.Objectorg.apache.derby.impl.jdbc.Util
public abstract class Util
This class understands the message protocol and looks up SQLExceptions based on keys, so that the Local JDBC driver's messages can be localized. REMIND: May want to investigate putting some of this in the protocol side, for the errors that any Derby JDBC driver might return. The ASSERT mechanism is a wrapper of the basic services, to ensure that failed asserts at this level will behave well in a JDBC environment.
