Detailed Description

template<typename Cmp1, typename Cmp2>
struct OpenMS::LexicographicComparator< Cmp1, Cmp2 >

A wrapper class that combines two comparators lexicographically. Normally you should use the make-function lexicographicComparator() because then you do not need to specify the template arguments.

Both comparators should of course have the same argument types. The result_type is bool, that is, we perform a two-way comparison like less<> and its relatives.

The usage is similar to pointerComparator() or reverseComparator(), which see.
