Binding To User Interface
ECO contains components for easy linking user interface controls to the domain objects. These components are so called handles. There are different types of handles in ECO. One of the most useful is expression handle which allows populating user interface controls with the results of an OCL expression. For example it is possible to show all people with name containing "John" by a handle with following expression:
Person.AllInstances->select(fullName.sqlLike('%John%')).
