RRRRWWWWTTTTPPPPttttrrrrSSSSeeeetttt requires the Standard C++ Library. DDDDeeeessssccccrrrriiiippppttttiiiioooonnnn This class maintains a pointer-based collection of values, which are ordered according to a comparison object of type CCCC. Class TTTT is the type pointed to by the items in the collection. CCCC must induce a total ordering on elements of type TTTT via a public member bool operator()(const T& x, const T& y) which returns ttttrrrruuuueeee if xxxx should precede yyyy within the collection. The structure lllleeeessssssss<<<<TTTT>>>> from the C++-standard header file <<<<ffffuuuunnnnccccttttiiiioooonnnnaaaallll>>>> is an example. Note that items in the collection will be dereferenced before being compared. RRRRWWWWTTTTPPPPttttrrrrSSSSeeeetttt<<<<TTTT,,,,CCCC>>>> will not accept an item that compares equal to an item already in the collection. (RRRRWWWWTTTTPPPPttttrrrrMMMMuuuullllttttiiiiSSSSeeeetttt<<<<TTTT,,,,CCCC>>>> may contain multiple items that compare equal to each other.) Equality is based on the comparison object and not on the ======== operator. Given a comparison object ccccoooommmmpppp, items aaaa and bbbb are equal if !comp(a,b) && !comp(b,a). PPPPeeeerrrrssssiiiisssstttteeeennnncccceeee Isomorphic. EEEExxxxaaaammmmpppplllleeeessss In this example, a pointer-based set of RRRRWWWWCCCCSSSSttttrrrriiiinnnnggggs is exercised.
