Class DelegatingDataSource

  • All Implemented Interfaces:
    java.sql.Wrapper, javax.sql.CommonDataSource, javax.sql.DataSource
    public class DelegatingDataSource
extends java.lang.Object
implements javax.sql.DataSource
    JDBC DataSource implementation that delegates all calls to a given target DataSource.

    This class is meant to be subclassed, with subclasses overriding only those methods (such as getConnection()) that should not simply delegate to the target DataSource.

    Since:
    1.1
