Detailed Description

template<typename T>
class blender::VArraySpan< T >

In many cases a virtual array is a span internally. In those cases, access to individual could be much more efficient than calling a virtual method. When the underlying virtual array is not a span, this class allocates a new array and copies the values over.

This should be used in those cases:

• All elements in the virtual array are accessed multiple times.
• In most cases, the underlying virtual array is a span, so no copy is necessary to benefit from faster access.
• An API is called, that does not accept virtual arrays, but only spans.
