Detailed Description

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

Utility class to reduce code duplication for methods available on #VArray and #VMutableArray. Deriving #VMutableArray from #VArray would have some issues:

Static methods on #VArray would also be available on #VMutableArray.
It would allow assigning a #VArray to a #VMutableArray under some circumstances which is not allowed and could result in hard to find bugs.

Member Typedef Documentation

◆ Storage

template<typename T >

using blender::VArrayCommon< T >::Storage = Any<blender::detail::VArrayAnyExtraInfo<T>, 24, 8>

protected

Store the virtual array implementation in an #Any. This makes it easy to avoid a memory allocation if the implementation is small enough and is copyable. This is the case for the most common virtual arrays. Other virtual array implementations are typically stored as #std::shared_ptr. That works even when the implementation itself is not copyable and makes copying VArrayCommon cheaper.
