conversion of (filtrations of) simplicial complex(es) to directed complexes #12

Closed vitskov closed 5 years ago

vitskov commented 6 years ago

vertices of directed complexes have fixed type: Array{Int16,1}

conversion is a pain, since currently simplicial complexes and combinatorial codes are created with arbitrary type.

Needed: function DirectedCodeword(sigma::CodeWord)::DirectedCodeword

  1. What is the canonical sorting order for sigma? Julia does not guarantee that the elements of a Set are stored in any particular order.
  2. Can you provide a short snippet of code demonstrating the problem?

This is I currently do to run around this problem:

function ConvertToDirectedCodeword(σ::Union{CodeWord,Set{Int8}})::DirectedCodeword if isempty(σ) return EmptyDirectedCodeword else return TheIntegerType.(sort(collect(σ))); end end
