Public Member Functions
void	ResetGraph ()
	Free up all the memory and clear the lists.

void	BeginMask (bool isMaskingEnabled, bool useAlphaTest, bool drawBehind, bool drawInFront) override
	Begin the setup of a mask render node, primitives added between this call and StartChildrenForMask define the mask.

void	StartChildrenForMask () override
	Start defining the children (masked primitives) of a mask.

void	EndMask () override
	End the setup of a mask render node, this marks the end of adding child primitives.

void	BeginRenderToTexture (AZ::Data::Instance< AZ::RPI::AttachmentImage > attachmentImage, const AZ::Vector2 &viewportTopLeft, const AZ::Vector2 &viewportSize, const AZ::Color &clearColor) override
	Begin rendering to a texture.

void	EndRenderToTexture () override
	End rendering to a texture.

LyShine::UiPrimitive *	GetDynamicQuadPrimitive (const AZ::Vector2 *positions, uint32 packedColor) override

bool	IsRenderingToMask () const override
	Get flag that indicates we are rendering into a mask. Used to avoid masks on child mask elements.

void	SetIsRenderingToMask (bool isRenderingToMask) override
	Set flag that we are rendering into a mask. Used to avoid masks on child mask elements.

void	PushAlphaFade (float alphaFadeValue) override
	Push an alpha fade, this is multiplied with any existing alpha fade from parents.

void	PushOverrideAlphaFade (float alphaFadeValue) override
	Push a new alpha fade value, this replaces any existing alpha fade.

void	PopAlphaFade () override
	Pop an alpha fade off the stack.

float	GetAlphaFade () const override
	Get the current alpha fade value.

void	AddPrimitive (LyShine::UiPrimitive *primitive, const AZ::Data::Instance< AZ::RPI::Image > &texture, bool isClampTextureMode, bool isTextureSRGB, bool isTexturePremultipliedAlpha, BlendMode blendMode) override
	Add an indexed triangle list primitive to the render graph with given render state.

void	AddAlphaMaskPrimitive (LyShine::UiPrimitive *primitive, AZ::Data::Instance< AZ::RPI::AttachmentImage > contentAttachmentImage, AZ::Data::Instance< AZ::RPI::AttachmentImage > maskAttachmentImage, bool isClampTextureMode, bool isTextureSRGB, bool isTexturePremultipliedAlpha, BlendMode blendMode) override
	Add an indexed triangle list primitive to the render graph which will use maskTexture as an alpha (gradient) mask.

void	Render (UiRenderer *uiRenderer, const AZ::Vector2 &viewportSize)
	Render the display graph.

void	SetDirtyFlag (bool isDirty)
	Set the dirty flag - this also resets the graph.

bool	GetDirtyFlag ()
	Get the dirty flag.

void	FinalizeGraph ()
	End the building of the graph.

bool	IsEmpty ()
	Test whether the render graph contains any render nodes.

void	GetRenderTargetsAndDependencies (LyShine::AttachmentImagesAndDependencies &attachmentImagesAndDependencies)

void	ValidateGraph ()

		uint32	packedColor
	)

overridevirtual

Get a dynamic quad primitive that can be added as an image primitive to the render graph The graph handles the allocation of this DynUiPrimitive and deletes it when the graph is reset This can be used if the UI component doesn't want to own the storage of the primitive. Used infrequently, e.g. for the selection rect on a text component.
