## org.quartz.impl.jdbcjobstore
Class StdJDBCDelegate

    java.lang.Object
      org.quartz.impl.jdbcjobstore.StdJDBCDelegate

All Implemented Interfaces:
  Constants, DriverDelegate, StdJDBCConstants

Direct Known Subclasses:
  CloudscapeDelegate, DB2v6Delegate, DB2v7Delegate, DB2v8Delegate, HSQLDBDelegate, MSSQLDelegate, OracleDelegate, PointbaseDelegate, PostgreSQLDelegate, WebLogicDelegate

public class StdJDBCDelegate
extends Object
implements DriverDelegate, StdJDBCConstants

This is meant to be an abstract base class for most, if not all, ``DriverDelegate`` implementations. Subclasses should override only those methods that need special handling for the DBMS driver in question.
