Interface ConnectionBuilder


  • public interface ConnectionBuilder
    A builder created from a DataSource object, used to establish a connection to the database that the data source object represents. The connection properties that were specified for the data source are used as the default values by the ConnectionBuilder.

    The following example illustrates the use of ConnectionBuilder to create a Connection:

    
         DataSource ds = new MyDataSource();
         ShardingKey superShardingKey = ds.createShardingKeyBuilder()
                               .subkey("EASTERN_REGION", JDBCType.VARCHAR)
                               .build();
         ShardingKey shardingKey = ds.createShardingKeyBuilder()
                               .subkey("PITTSBURGH_BRANCH", JDBCType.VARCHAR)
                               .build();
         Connection con = ds.createConnectionBuilder()
                           .user("rafa")
                           .password("tennis")
                           .setShardingKey(shardingKey)
                           .setSuperShardingKey(superShardingKey)
                           .build();
