To access large amounts of external data, a lookup call typically invokes a so called lookup service that is providing the necessary data. In the other case, the lookup data is dynamic in nature, the amount of data is large and needs to be read from some external source, such as a database or a web service. In this situation, the lookup data can be directly created in the call itself.Īs an example, you may consider a lookup call where the lookup data is based on a code type. In the first case, the lookup data is locally available, not too large and can be kept in memory. The Scout SDK takes care of this time consuming and error prone task.įor lookup calls two main use cases exist.

This includes adding all the necessary getter and setter methods to access the values of all the fields defined on a form.Īs a result, Scout developers don’t need to manually update form data objects when the UI model of a form is changed.
In consequence, the Scout SDK can update form field classes in the background even when form fields are manually coded into the form’s Java class. It is important to note that this mechanism only depends on the Java code of the form field class. However, this is not the only benefit for the Scout SDK.Īs form data objects hold all form variables and the values of all form fields contained in the form, the Scout SDK can keep the form data classes in sync with the forms of the application. It allows the Scout SDK to easily parse the form’s Java code on the fly and directly reflect changes to the form model in the Scout Explorer and the Scout Property View. Using inner Java classes to model a form’s content is a central aspect of the UI part of the Scout application model.
