Detailed Description

DeviceResourceView is a base class for views which are dependent on a DeviceResource 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

◆ IsFullView()

virtual bool AZ::RHI::DeviceResourceView::IsFullView ( ) const
pure virtual

Returns whether the view covers the entire image (i.e. isn't just a subset).

Implemented in AZ::RHI::DeviceBufferView, and AZ::RHI::DeviceImageView.

◆ IsStale()

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

Returns whether this view is stale (i.e. the original image contents have been shutdown.
