Interface DriverDelegate

All Known Implementing Classes:

CacheDelegate, CUBRIDDelegate, DB2v6Delegate, DB2v7Delegate, DB2v8Delegate, HSQLDBDelegate, MSSQLDelegate, OracleDelegate, PointbaseDelegate, PostgreSQLDelegate, StdJDBCDelegate, SybaseDelegate, WebLogicDelegate, WebLogicOracleDelegate

public interface DriverDelegate

This is the base interface for all driver delegate classes.

This interface is very similar to the JobStore interface except each method has an additional Connection parameter.

Unless a database driver has some extremely-DB-specific requirements, any DriverDelegate implementation classes should extend the StdJDBCDelegate class.
