- Fixed all Dynamic and Static entities lacking proper destructors: Dynamic entities need to delete Dynamic children, Static entities need only to delete them from the list of their siblings - Added methods to get Static "core" from Dynamic*. - Now get_core() is a pure virtual function into DynamicSchedulable. A quite nice solution(?), really, if I can say that myself... ;-) - ConcreteHistory is half-implemented. It's the other half that worries me. - TODO: finish off ConcreteHistory, and check that things get destroyed properly (no leaks allowed, use valgrind). - TODO: rework Simulation - TODO: Scheduler rewrite - *A side note*: this code is becoming a mess. I prefer references over pointers, but someone other prefer pointers over references, and what happens is that you've to continously pass from one to another when invoking other methods... this is bad. git-svn-id: svn://svn.gna.org/svn/sgpemv2/trunk@694 3ecf2c5c-341e-0410-92b4-d18e462d057c
