Detailed Description

FrameAttachment is the base class for all attachments stored in the frame graph. Attachments are "attached" to scopes via ScopeAttachment instances. These scope attachments form a linked list from the first to last scope. FrameAttachments are associated with a unique AttachmentId.

FrameAttachments are rebuilt every frame, and are created through the FrameGraph.

Member Function Documentation

Scope* AZ::RHI::FrameAttachment::GetFirstScope

(

)

const

Returns the first / last scope associated with the lifetime of this attachment. The guarantee is that the attachment is not used by any scope with index prior to GetFirstScope or any scope with index after GetLastScope. It does not, however, guarantee that the attachment is actually used by either scope. The scope attachment list must be traversed to determine usage.
