 ==== Queries ====
-In GroIMP the project graph is considered to hold almost all information on the simulation. Therefore it can also be seen as a knowledge graph. To retrieve this knowledge rgg uses the [[tutorials:common_graph_queries|XL query system]]. To use this queries in a java block they have to be framed by ''(*...*)'' as shown in the examples below. In that way they return a collection object, which then can be like other java objects. Moreover GroIMP comes with a set of predefined  [[:15_cheatsheet:operators|Analytical methods]] to analyze this collections.

 As shown in the example below in ''%%count((*M*))%%'' this queries work with the concept of java objects. Therefore ''(*M*)'' is selecting all instances of Branch because Branch extends M. This also works with interfaces.
