SimplexTreeOptions::Filtration_value
FiltrationValue Filtration_value
Must be comparable with operator<.
Definition: SimplexTreeOptions.h:23
SimplexTreeOptions::store_key
static const bool store_key
If true, each simplex has extra storage for one Simplex_key. Necessary for Persistent_cohomology.

SimplexTreeOptions::stable_simplex_handles
static const bool stable_simplex_handles
If true, Simplex_handle will not be invalidated after insertions or removals.
Definition: SimplexTreeOptions.h:39
SimplexTreeOptions::contiguous_vertices
static constexpr bool contiguous_vertices
If true, the list of vertices present in the complex must always be 0, ..., num_vertices-1,...
