	plPipelineBarrierVulkan (plAllocator *pAllocator)
Barrier handling
void	SetCommandBuffer (vk::CommandBuffer *pCommandBuffer)
	Set the active command buffer that barriers are flushed into.
void	Flush ()
	Flush accumulated changes as a barrier into the active command buffer.
void	Submit ()
	Should be called when the active command buffer is submitted. This clear various states as a submit works like a full barrier.
void	FullBarrier ()
	Full barrier for debugging purposes.
bool	IsDirty () const
Buffer handling
void	BufferDestroyed (const plGALBufferVulkan *pBuffer)
	Need to be called to remove the buffer from tracking.
void	AccessBuffer (const plGALBufferVulkan *pBuffer, vk::DeviceSize offset, vk::DeviceSize length, vk::PipelineStageFlags srcStages, vk::AccessFlags srcAccess, vk::PipelineStageFlags dstStages, vk::AccessFlags dstAccess)

Image handling
void	SetInitialImageState (const plGALTextureVulkan *pTexture, vk::ImageLayout dstLayout, vk::PipelineStageFlags dstStages=vk::PipelineStageFlagBits::eTopOfPipe, vk::AccessFlags dstAccess={})
	Force, sets the layout of the texture's image. Most images are not created in their preferred layout on creation.
void	TextureDestroyed (const plGALTextureVulkan *pTexture)
	Need to be called to remove the texture's image from tracking.
void	EnsureImageLayout (const plGALTextureVulkan *pTexture, vk::ImageLayout dstLayout, vk::PipelineStageFlags dstStages, vk::AccessFlags dstAccess, bool bDiscardSource=false)
	Transition the given texture's image into the given layout to be used in the given stage.

Member Function Documentation

EnsureImageLayout()

void plPipelineBarrierVulkan::EnsureImageLayout	(	const plGALTextureVulkan *	pTexture,
		vk::ImageLayout	dstLayout,
		vk::PipelineStageFlags	dstStages,
		vk::AccessFlags	dstAccess,
		bool	bDiscardSource = false )

Transition the given texture's image into the given layout to be used in the given stage.

Parameters

pTexture	The texture whose image's layout is to be changed.
dstLayout	The layout that the image is to be changed into.
dstStages	In what stages the image needs to be in the new layout.
dstAccess	What access we will be doing on the image in dstStages.
bDiscardSource	Discard the previous layout, replaces current layout with unknown.

SetInitialImageState()

void plPipelineBarrierVulkan::SetInitialImageState	(	const plGALTextureVulkan *	pTexture,
		vk::ImageLayout	dstLayout,
		vk::PipelineStageFlags	dstStages = vk::PipelineStageFlagBits::eTopOfPipe,
		vk::AccessFlags	dstAccess = {} )

Force, sets the layout of the texture's image. Most images are not created in their preferred layout on creation.

Parameters

pTexture	The texture whose image the initial state should be set on.
dstLayout	The layout that the image currently is in.
dstStages	In what stage the image was changed into the current layout.
dstAccess	The access operation that changed the image into the current layout during dstStages.
