EMF-IncQuery: Blazing Fast Reaction Times Even for Very Large Diagrams

Paris, France, December 03, 2015     Dr. Horváth Ákos     Share

EMF-IncQuery is a the state-of-the-art live model query engine of the Eclipse ecosystem

This talk introduces an extension to Sirius that combines the advanced visualization features of Sirius with the power of live model search provided by EMF-IncQuery to define automatically synchronized views. EMF-IncQuery, the state-of-the-art live model query engine of the Eclipse ecosystem, avoids the recalculation of views from scratch after each individual source model change, and provides blazing fast reaction times even for very large diagrams.

The highlights of the talk are:

IncQueries for interpreted expressions: We demonstrate how we integrated the IncQuery query language into Sirius to provide an alternative high-performance interpreted expression language besides the built-in AQL. As a novelty, our approach supports automatic diagram updates by change impact analysis by initiating a refresh only when a change in the source model affects an element in the view.

Live abstractions: We highlight how easy it is to define additional non-persisted derived views based on a combination of a Sirius diagram definition and a set of queries on your original model. Such live abstractions can provide a significant boost to the usability of your modeling tool, by giving the user the ability to create abstract or compact and automatically updated graphical views of their models, without Java coding.

Scalability: Finally, we present an initial scalability measurement to demonstrate how our query-driven views can scale up to industrial size models (the “one million model element” challenge) within a cyber-physical system context.
