An efficient computation strategy for allInstances()

Research output: Contribution to journalArticlepeer-review


Contemporary model query and transformation engines typically provide built-in facilities for retrieving all instances of a particular type/kind regardless of their location in a model (i.e. OCL's allInstances()). When implemented in a naive manner, such facilities can be computationally expensive for large models. We contribute a novel approach for implementing allInstances()-like facilities for EMF models, which makes use of static analysis and metamodel introspection and we report on the results of extensive benchmarking against alternative approaches.
