std::map and comparison function

[ImNotaBot]

EDIT: SOLVED!

Hi

once again i need your help.

I have a struct representing a poker hand category.

typedef struct{
  int rank1;
  int rank2;
  bool isSuited;
}HAND169;

I want to precalculate the equity of every category against every category. Hence i want to make a table:

typedef map<HAND169, map<HAND169, pair<double,double>>> LOOKUP1ON1;

Now, if i want to work with this map, the compiler desires a comparison function from me. But i really have no clue how to implement it. I dont understand the example at http://www.cplusplus.com/reference/stl/map/map/ and the numerous articles in the web did not help me. Can you please help me with it?

EDIT: SOLUTION

typedef struct{
  int rank1;
  int rank2;
  bool isSuited;
}HAND169;

struct classcomp {
  bool operator() (const HAND169 &h1, const HAND169 &h2) const
  {
    if (h1.rank1 < h2.rank1)
      return true;
    else if (h1.rank1 == h2.rank1 && h1.rank2 < h2.rank2)
      return true;
    else if (h1.rank1 == h2.rank1 && h1.rank2 == h2.rank2 && h1.isSuited < h2.isSuited)
      return true;
    return false;
  }
};

typedef map<HAND169, map<HAND169, pair<double,double>,classcomp>, classcomp> LOOKUP1ON1 ;

Forgot the inner map. Anyway thanks for reading ;-D
