any way to simplify this with a form of dynamic class instantiation?
- by gnychis
I have several child classes that extend a parent class, forced to have a uniform constructor. I have a queue which keeps a list of these classes, which must extend MergeHeuristic. The code that I currently have looks like the following:
Class<? extends MergeHeuristic> heuristicRequest = _heuristicQueue.pop();
MergeHeuristic heuristic = null;
if(heuristicRequest == AdjacentMACs.class)
heuristic = new AdjacentMACs(_parent);
if(heuristicRequest == SimilarInterfaceNames.class)
heuristic = new SimilarInterfaceNames(_parent);
if(heuristicRequest == SameMAC.class)
heuristic = new SameMAC(_parent);
Is there any way to simplify that to dynamically instantiate the class, something along the lines of:
heuristic = new heuristicRequest.somethingSpecial();
That would flatten that block of if statements.
