Examples of org.eclipse.sapphire.VersionCompatibilityTargetService

org.eclipse.sapphire.VersionCompatibilityTargetService
Produces the version compatibility target to be referenced by VersionCompatibilityService. Most frequently specified via an @VersionCompatibilityTarget annotation.
When looking for the version compatibility target, the framework will first check the property, then the containing element, then the parent property and the parent element, etc. The search continues until version compatibility target is found or the model root is reached.
