Detailed Description

template<typename Incidence_type_, typename Filtration_type_, typename Additional_information_ = void>
class Gudhi::Hasse_diagram::Hasse_diagram_cell< Incidence_type_, Filtration_type_, Additional_information_ >

Data structure to store a cell in a Hasse diagram.

The use and interfaces of this Hasse diagram cell is limited to the Coxeter triangulation implementation.

This is a data structure to store a cell in a general Hasse diagram data structure. It stores the following information about the cell: References to boundary and coBoundary elements, dimension of a cell and its filtration. It also allow to store any additional information of a type Additional_information which is a template parameter of the class (set by default to void).

The complex is a template class requiring the following parameters: Incidence_type_ - determine the type of incidence coefficients. Use integers in most general case. Filtration_type_ - type of filtration of cells. Additional_information_ (set by default to void) - allows to store any additional information in the cells of Hasse diagrams.

Examples
