Syntax

template<typename ViewType>
class TMeshAttributesViewBase

Remarks

This is the class used to provide a 'view' of the specified type on an attribute array. Like TMeshAttributesRef, it is a proxy object which is valid for as long as the owning FMeshDescription exists, and should be passed by value.

This is the base class, and shouldn't be instanced directly.
