Detailed Description

ResourceView is a base class for views which are dependent on a Resource instance.

NOTE: While initialization is separate from creation, explicit shutdown is not allowed for resource views. This is because the cost of dependency tracking with ShaderResourceGroups is too high. Instead, resource views are reference counted.

Member Function Documentation

bool AZ::RHI::ResourceView::IsStale ( ) const
