ref()

void SkRefCntBase::ref ( ) const

Increment the reference count.

Must be balanced by a call to unref().

(

const sk_sp< RenderNode > &

)

render()

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

inherited

size()

size_t sksg::Group::size ( ) const

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.
