Semantic Browser - eclipse-capella/capella GitHub Wiki

By providing queries on Semantic Browser, these queries will be also available as a column on Mass Visualization table or accessible in Title Block.

The extension point is provided by:

• the plug-in org.polarsys.capella.common.ui.toolkit.browser
• and its identifier contentProviderCategory.

The contribution to the extension point is done in the plugin.xml file of the plugin. Open this file and focus on the plugin.xml tab:

• availableForType: class: an EClass class on which the query will be applied
• targetBrowserId: one of ReferencingElementBrowser - CurrentElementBrowser - ReferencedElementBrowser
• basicQuery: class: a java class inheriting of org.polarsys.capella.common.helpers.query.IQuery
• itemQueries.basicQuery: class: a sub query applied on all retrieved elements. For intance, for a Function, you can retrieve the outgoing exchanges, and displaying for them their target functions.

For a Functional Exchange, we display its allocated Exchange Items and their data.

• The Java class retrieving the Exchange Items

• The secondary Java class retrieving the Exchange Items Elements for Exchange Items

• Its registration within plugin.xml

• In MANIFEST/MANIFEST.MF file we need to depend on org.polarsys.capella.core.model.helpers
