Inheritance diagram for Foundation::RHI::RHIBuffer:

Public Member Functions
	RHIBuffer (RHIDevice const &device, RHIBufferDesc const &desc)
virtual void *	Map ()=0
	Maps the entire buffer to the host memory. Alignment is implementation-defined. Implementations MUST guarantee consecutive calls to Map() return the same pointer, therefore it's not possible to map the same resource multiple times. For caching behaviours, RHIBufferDesc.
virtual void	Flush (size_t offset=0, size_t size=kFullSize)=0
	Flushes the mapped region to the device. Depending on the implementation, this may be a no-op.
virtual void	Unmap ()=0
	Releases or unmaps a previously mapped resource. Implementations MUST guarantee that Unmap() is called at destruction time if the resource is still mapped.
template<typename T >
Span< T >	MapSpan (size_t count=kFullSize)
	Creates a span that maps a contiguous region of the buffer to the host memory. Behaviour of the memory access is defined by the resource itself. e.g. RO/RW. It is undefined behaviour to access the memory without regard to the resource's host access type. For detailed mapping behaviour, Map
template<typename T >
T *	Map ()
	Maps as pointer of T.

Member Function Documentation

CreateAliasedBuffer()

virtual RHIBufferScopedHandle< RHIBuffer > Foundation::RHI::RHIBuffer::CreateAliasedBuffer ( RHIBufferDesc const &  desc, size_t  offset = 0  )

pure virtual

Implemented in Foundation::RHI::VulkanBuffer.

DebugSetObjectName()

virtual void Foundation::RHI::RHIBuffer::DebugSetObjectName ( const char *  name )

pure virtual

Implemented in Foundation::RHI::VulkanBuffer.

DestroyAliasedBuffer()

virtual void Foundation::RHI::RHIBuffer::DestroyAliasedBuffer ( Handle  handle )

pure virtual

Implemented in Foundation::RHI::VulkanBuffer.

Flush()

virtual void Foundation::RHI::RHIBuffer::Flush ( size_t  offset = 0, size_t  size = kFullSize  )

pure virtual

Flushes the mapped region to the device. Depending on the implementation, this may be a no-op.

Implemented in Foundation::RHI::VulkanBuffer.

GetAliasedBuffer()

virtual RHIBuffer * Foundation::RHI::RHIBuffer::GetAliasedBuffer ( Handle  handle ) const

pure virtual

Implemented in Foundation::RHI::VulkanBuffer.

GetAllocationSize()

virtual size_t Foundation::RHI::RHIBuffer::GetAllocationSize ( ) const

pure virtual

Implemented in Foundation::RHI::VulkanBuffer.

Map() [1/2]

template<typename T >

T * Foundation::RHI::RHIBuffer::Map ( )

inline

Maps as pointer of T.

Map() [2/2]

virtual void * Foundation::RHI::RHIBuffer::Map ( )

pure virtual

Maps the entire buffer to the host memory. Alignment is implementation-defined. Implementations MUST guarantee consecutive calls to Map() return the same pointer, therefore it's not possible to map the same resource multiple times. For caching behaviours, RHIBufferDesc.

Implemented in Foundation::RHI::VulkanBuffer.

MapSpan()

template<typename T >

Span< T > Foundation::RHI::RHIBuffer::MapSpan ( size_t  count = kFullSize )

inline

Creates a span that maps a contiguous region of the buffer to the host memory. Behaviour of the memory access is defined by the resource itself. e.g. RO/RW. It is undefined behaviour to access the memory without regard to the resource's host access type. For detailed mapping behaviour, Map

Parameters

count

count of elements

Unmap()

virtual void Foundation::RHI::RHIBuffer::Unmap ( )

pure virtual

Releases or unmaps a previously mapped resource. Implementations MUST guarantee that Unmap() is called at destruction time if the resource is still mapped.

Implemented in Foundation::RHI::VulkanBuffer.
