Altova UModel 2020 Professional Edition

It is important to check the syntax of the project before generating code from the model. This will inform you of any problems which prevent code from being generated. Project syntax can be checked from the menu command Project | Check Project Syntax (alternatively, press F11). A syntax check will also be performed automatically before code is updated from the model. The results (errors, warnings, and information messages) are reported in the Messages window.

 

When a syntax check is performed, the project file is checked on multiple levels as detailed in the tables below. Note the following:

 

For information about solving common syntax errors, see the Code generation prerequisites.

For components, the checks below are performed only if the use for code engineering property is enabled for the component in the Properties window.

For classes, interfaces, and enumerations, the checks below are performed only if the class, interface, enumeration is contained in a code language namespace. In other words, it must be under a package which has been defined as namespace root.

Constraints on model elements are not checked, as they are not part of the code generation process, see Constraining Elements.
