question: public boolean addBound ( TypeBound bound ) { if ( bound . isTrivial ( ) ) { return false ; } final boolean wasAdded = internal_addBound ( bound ) ; if ( DEBUG ) { final String suffix = wasAdded ? "  (ADDED)" : "  (not added; already present)" ; log ( ">>> ADD bound: " + bound + suffix ) ; } return wasAdded ; }
target:  Adds a type bound to this set. Does not itself trigger incorporation; this must be done by caller if(!) this method returns true.
