LocalSearch internal API break
The method org.eclipse.viatra.query.runtime.localsearch.planner.LocalSearchPlanner.initializePlanner(PQueryFlattener, Logger, IQueryMetaContext, IQueryRuntimeContext, PBodyNormalizer, LocalSearchRuntimeBasedStrategy, POperationCompiler, Map<String,Object>) has been removed. The initialization is performed by the constructor, which has the following signature: LocalSearchPlanner(LocalSearchBackend, Logger, PlannerConfiguration).
Internal engine API changes
Hint system refactor
In VIATRA 0.9 a preliminary hint system was introduced, where it was possible to provide hints for query evaluation. In version 1.4, this hint system was extended; however, VIATRA 1.4 cannot handle hints for queries generated with older versions of VIATRA. Please, regenerate your queries with 1.4 if you want to use hints.
Updated runtime context API
The IQueryRuntimeContext interface was extended with a few new methods, related to the usage of Base indexer. For the future, it is recommended that implementors do not implement this class directly, but rely on the new AbstractQueryRuntimeContext base class instead.
DSE API breaks
- Three plug-ins (
.dse.api,.dse.base,.dse.designspace) has been restructured to a single plug-in:org.eclipse.viatra.dse. Manifest files should be updated accordingly.
