Allow setting a global variable (for example a service) which can be used by the score rules -------------------------------------------------------------------------------------------- Key: JBRULES-2700 URL: https://issues.jboss.org/browse/JBRULES-2700 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Components: drools-planner Reporter: Wouter Horré Assignee: Geoffrey De Smet Currently, it is not possible to set a global variable in the working memory used by the solver. If a scoring rule needs an external helper for calculating scores (e.g. a dependency injected with OSGi DS), a workaround using a static variable in some class accessible by the scoring rules is needed. The easiest implementation is probably a new method in the Solver interface: // Impossible public WorkingMemory getWorkingMemory(); which provides access to the working memory used by the solver. => Impossible because the number of WorkingMemory equals the number of threads being used by Planner, and sometimes they are reset.
