bool	operator() (const Vector &a, const Vector &b) const
	Defines an increasing-order comparison between two vectors of real numbers.

Detailed Description

Comparison functor for codac2::Vector objects.

This functor defines a strict weak ordering on codac2::Vector objects so that they can be used as keys in associative containers such as std::map. The ordering is based on increasing real values, inspected sequentially from index 0 to the last. If all corresponding components are equal, the operator returns false to indicate that neither vector is strictly less than the other.

Member Function Documentation

operator()()

bool codac2::VectorCompare::operator() ( const Vector & a, const Vector & b ) const

inline

Defines an increasing-order comparison between two vectors of real numbers.

Parameters

a	The first vector to compare.
b	The second vector to compare.

Returns

true if a is considered strictly smaller than b, false otherwise.

    {
      if(a.size() != b.size())
        return a.size() < b.size();
 
      for(Index i = 0 ; i < a.size() ; i++)
        if(a[i] != b[i])
          return a[i] < b[i];
 
      return false;
    }
