Creating an Entity

Let’s create a CountryGrowth entity class.

1. In the Data Model section of the CUBA project tree click New → Entity. The New CUBA Entity dialog window will appear.

2. Enter the name of the entity class – CountryGrowth – in the Entity name field, choose Not persistent for Entity type and click OK button. The entity designer page will be displayed in the workspace.

3. Using Entity Designer add attributes:

   • country of the type String

   • year2014 of the type Double

   • year2015 of the type Double

4. Switch to the Text tab. It contains the source code of the CountryGrowth class.

   link:../../../../../source/chart/CountryGrowth.java[role=include]

   This class describes a non-persistent entity. An instance of this class contains the number of the country GDP growth rate for 2014 and 2015 years.

CountryGrowth entity creation is now complete.
