Code Inspection: Unused declaration
Reports the classes, methods, functions, constants, or properties that are not used or not reachable from entry points. It also reports all method implementations/overriders.
Some unused members might not be reported in the code editor on the fly. Due to performance reasons, a non-private member is checked only when its name rarely occurs in the project.
To see all results, run the inspection in batch mode by using Code | Inspect Code... or Code | Run Inspection by Name....
