Detailed Description

BufferView is contains a platform-specific descriptor mapping to a linear sub-region of a specific buffer resource. It associates 1-to-1 with a BufferViewDescriptor.

Member Function Documentation

◆ GetBindlessReadIndex()

virtual uint32_t AZ::RHI::BufferView::GetBindlessReadIndex ( ) const
inlinevirtual

Reimplemented in AZ::Metal::BufferView.

◆ IgnoreFrameAttachmentValidation()

bool AZ::RHI::BufferView::IgnoreFrameAttachmentValidation ( ) const
inline

Tells the renderer to ignore any validation related to this buffer's state and scope attachments. Assumes that the programmer is manually managing the Read/Write state of the buffer correctly.

◆ IsFullView()

bool AZ::RHI::BufferView::IsFullView ( ) const
finaloverridevirtual

Returns whether the view maps to the full buffer.

Implements AZ::RHI::ResourceView.
