question: @ SuppressWarnings ( "unchecked" ) private boolean canBind ( final Gearing gearing , final IBindingSet childSolutionIn , final IConstant < ? > seed ) { if ( gearing . outVar == null ) return seed . equals ( gearing . outConst ) ; if ( ! childSolutionIn . isBound ( gearing . outVar ) ) return true ; return seed . equals ( childSolutionIn . get ( gearing . outVar ) ) ; }
target:  Is it possible to bind the out of the gearing to the seed? This may be because it is an unbound variable, or it may be that it is already the seed  (either as a const or as a var)
