       +-- ApplicationContext (in package NeatTools.application)
            |
            +-- StateReady
                StateModuleSelected
                StateOutputSelected

StateReady Methods

inputSelected() - does nothing.
outputSelected() - changes application to StateOutputSelected.
moduleSelected() - changes application to StateModuleSelected.
nothingSelected() - does nothing.

StateModuleSelected Methods

inputSelected() - changes application to StateReady.
outputSelected() - changes application to StateOutputSelected. This change changes the module state of all modules with available compatible inputs to the Module state StateInputActivated.
moduleSelected() - if module is same as one selected, changes application to StateReady.
nothingSelected() - changes application to StateReady.

StateOutputSelected Methods

inputSelected() - if input is in a module that is in StateInputActivated (meaning the input is compatible with the currently selected output), changes application to StateReady.
outputSelected() - if output already selected, changes application to StateReady.
moduleSelected() - if module state is StateInputActivated, change application to StateReady.
nothingSelected() - changes application to StateReady.
