Example 1 with Receiver

use of org.qi4j.io.Receiver in project qi4j-sdk by Qi4j.

the class DataSourceConfigurationManagerServiceTest method init.

public void init(@Service @IdentifiedBy("testds") DataSource dataSource, @Service @IdentifiedBy("testds2") ServiceReference<DataSource> dataSource2) throws SQLException, PropertyVetoException {
    Databases databases = new Databases(dataSource);

    databases.query("select * from test").transferTo(Outputs.withReceiver(new Receiver<ResultSet, SQLException>() {

        @Override
        public void receive(ResultSet item) throws SQLException {
            System.out.println(item.getString("id"));
