Detailed Description

template<bool allowsNonorientable>
class regina::detail::FaceOrientability< allowsNonorientable >

Helper class that stores whether the link of a face is orientable.

Every class Face<dim, subdim> inherits from this class.

This class takes a template argument to allow optimisation for those dimensions in which face links are always orientable. In particular, if allowsNonorientable is false, then this class assumes that all faces will always have orientable links, and it optimises away all the implementation details to leave no overhead at all.

Template Parameters

allowsNonorientable

true when this is used for dimensions in which face links could potentially be non-orientable, or false when this is used for dimensions in which face links are always orientable.
