Remarks

Convenience for using a TSortedMap with FVertexName Key type.

This template makes it convenient to create a TSortedMap with an FVertexName while also avoiding compilation errors incurred from using the FName default "less than" operator in the TSortedMap implementation.

  • FVertexName is an alias to FName.
  • TSortedMap fails to compile since the "less than" operator specific implementation needs to be chosen (FastLess vs LexicalLess)
  • Due to the template argument order of TSortedMap this also forces you to choose the allocator.
  • This is all a bit of an annoyance to do every time we use a TSortedMap with an FVertexName as the key.
