Implemented in sksg::Matrix< T >.

◆ MakeConcat()

◆ observeInval()

protectedinherited

◆ onRevalidate()

virtual SkRect sksg::Node::onRevalidate ( InvalidationController *  ,
const SkMatrix &  ctm 
)
protectedpure virtualinherited

Implemented in sksg::TransformEffect, sksg::Matrix< T >, sksg::Text, sksg::ImageFilterEffect, sksg::ShaderEffect, sksg::RRect, sksg::Rect, sksg::Plane, sksg::Path, sksg::ShaderPaint, sksg::Color, sksg::OpacityEffect, sksg::Merge, sksg::MaskEffect, sksg::Image, sksg::Group, sksg::EffectNode, sksg::Draw, sksg::ClipEffect, sksg::ImageFilter, sksg::Shader, sksg::GeometryEffect, and sksg::ColorFilter.

◆ ref()

void SkRefCntBase::ref ( ) const
inlineinherited

Increment the reference count.

Must be balanced by a call to unref().

◆ revalidate()

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