MCont

Bean Container that supports mixed bean types

MCont is an extension to Vaadin BeanContainer where the contained beans can have different types (inheriting from a common base class) and consequently different sets of properties available.

MCont is also more efficient than BeanContainer in that more metadata is shared and Property instances are initialized lazily. This can lead to a significant reduction in memory usage in many cases.

Sample code

public class DemoContainer extends ExtensibleBeanContainer<String, Person> {

   public DemoContainer() {
        super(Person.class, Employee.class, Child.class);
        
        setBeanIdProperty("name");

        addBean(new Person("person"));
        addBean(new Employee("employee", "employer"));
        addBean(new Child("child", "rubber duck"));
    }
}
