  • All Implemented Interfaces:
    ConnectionCustomizer
    Direct Known Subclasses:
    InitSqlConnectionCustomizer
    public abstract class AbstractConnectionCustomizer
extends java.lang.Object
implements ConnectionCustomizer
    An abstract implementation of the ConnectionCustomizer interface in which all methods are no-ops. Just a convenience class since most clients will only need to implement a single method.

                      java.lang.String parentDataSourceIdentityToken)
               throws java.lang.Exception
        Description copied from interface: ConnectionCustomizer

        Called immediately after a Connection is acquired from the underlying database for incorporation into the pool.

        This method is only called once per Connection. If standard JDBC Connection properties are modified — specifically catalog, holdability, transactionIsolation, readOnly, and typeMap — those modifications will override defaults throughout the Connection's tenure in the pool.
