Expose a circulator type to Python.

Template Parameters

Circulator A circulator type.

Parameters

_name The name of the circulator type to be exposed.

Note: Circulators are wrapped by CirculatorWrapperT before they are exposed to Python, i.e. they are not exposed directly. This means that circulators that are passed from Python to C++ are instances of CirculatorWrapperT.

template<class Iterator , size_t(OpenMesh::ArrayKernel::*)() const n_items>

Parameters

_name The name of the iterator type to be exposed.

Note: Iterators are wrapped by IteratorWrapperT before they are exposed to Python, i.e. they are not exposed directly. This means that iterators that are passed from Python to C++ are instances of IteratorWrapperT.
