◆ nodeAt()

const RenderNode* sksg::RenderNode::nodeAt ( const SkPoint &  point) const

◆ observeInval()

void sksg::Node::observeInval ( const sk_sp< Node > &  )

◆ onNodeAt()

const RenderNode* sksg::EffectNode::onNodeAt ( const SkPoint &  ) const
overrideprotectedvirtualinherited

Implements sksg::RenderNode.

Reimplemented in sksg::TransformEffect, sksg::BlenderEffect, sksg::ImageFilterEffect, sksg::OpacityEffect, and sksg::MaskEffect.

◆ onRender()

void sksg::ShaderEffect::onRender ( SkCanvas *  ,
const RenderContext *   
) const
overrideprotectedvirtual

Reimplemented from sksg::EffectNode.

◆ onRevalidate()

SkRect sksg::ShaderEffect::onRevalidate ( InvalidationController *  ,
const SkMatrix &   
)
overrideprotectedvirtual

Reimplemented from sksg::EffectNode.

◆ ref()

void SkRefCntBase::ref ( ) const
inlineinherited

Increment the reference count.

Must be balanced by a call to unref().

◆ render()

void sksg::RenderNode::render ( SkCanvas *  ,
const RenderContext *  = nullptr 
) const
inherited

◆ revalidate()

const SkRect& sksg::Node::revalidate ( InvalidationController *  ,
const SkMatrix &   
)
inherited

◆ setShader()

void sksg::ShaderEffect::setShader ( sk_sp< Shader >  )

◆ setVisible()

void sksg::RenderNode::setVisible ( bool  )
inherited

◆ unique()

bool SkRefCntBase::unique ( ) const
inlineinherited

May return true if the caller is the only owner.

Ensures that all previous owner's actions are complete.

◆ unobserveInval()

void sksg::Node::unobserveInval ( const sk_sp< Node > &  )
protectedinherited

◆ unref()

void SkRefCntBase::unref ( ) const
inlineinherited

Decrement the reference count.

If the reference count is 1 before the decrement, then delete the object. Note that if this is the case, then the object needs to have been allocated via new, and not on the stack.
