Detailed Description

template<typename SelfType, typename ValueType, typename SizeType, typename AtFunc, typename SizeFunc>
class lass::python::FreeIndexedRangeView< SelfType, ValueType, SizeType, AtFunc, SizeFunc >

View that adapts index-based element access to a PyIteratorRange.

IndexedRangeView holds a ShadoweePtr to the container, and iterates ove the elements by index. It uses the supplied member functions atMethod and sizeMethod to access the elements and the size of the container.

It retrieves the size of the container by calling (self->*sizeMethod)() once when the iteration starts, and accesses the elements by calling (self->*atMethod)(index) for each index from 0 to size-1.

iter() produces a PyIteratorRange and sets self as its owner, keeping the container alive for the duration of the iteration.

Template Parameters

SelfType	C++ container type
ValueType	Element type returned by the container's iterators
SizeType	Argument type of AtMethod and return type of SizeMethod
AtMethod	Member function type of the element accessor; expected to accept a SizeType index and return a ValueType
SizeMethod	Member function type of the size accessor; expected to return a SizeType
