Detailed Description

template<typename ValueT, typename ReferenceT = ValueT&>
struct plask::PolymorphicForwardIteratorWithIndexImpl< ValueT, ReferenceT >

Base class for forward, polymorphic iterators implementations which allow to get index of current position.

It is similar to PolymorphicForwardIteratorImpl but has getIndex method.

Template Parameters

ValueT	Type to iterate over.
ReferenceT	Type returned by dereference operation. Note that default type is not good if dereference returns temporary object. In such case `const ValueT` can be a better choice.
