Detailed Description

template<typename TPixelType, typename TCellTraits>
class itk::CellInterface< TPixelType, TCellTraits >

Define an abstract interface for cells. Actual cell types derive from this class.

Extra information in cells that are actually boundaries between other cells is provided in the CellBoundary wrapper.

Template parameters for Cell:

TPixelType = The type stored with an entity (cell, point, or boundary).

TCellTraits = Type information for cell.
