    - #### isCompatibleWithQueryScope

          public boolean isCompatibleWithQueryScope​(java.lang.Class<? extends QueryScope> queryScopeClass)

      Description copied from class: `QueryScope`
      Determines whether a query engine initialized on this scope can evaluate queries formulated against the given scope type.

      Every query scope class is compatible with a query engine initialized on a scope of the same class or a subclass.

      Overrides:
        `isCompatibleWithQueryScope` in class `QueryScope`
      Parameters:
        `queryScopeClass` - the scope class returned by invoking `IQuerySpecification.getPreferredScopeClass()` on a query specification
      Returns:
        true if an `ViatraQueryEngine` initialized on this scope can consume an `IQuerySpecification`

    - #### createEngineContext

          protected IEngineContext createEngineContext​(ViatraQueryEngine engine,
                                                       IIndexingErrorListener errorListener,
                                                       org.apache.log4j.Logger logger)
