observeInval()

onMakeShader()

virtual sk_sp<SkShader> sksg::Gradient::onMakeShader ( const std::vector< SkColor4f > &  colors, const std::vector< SkScalar > &  positions  ) const

protectedpure virtual

Implemented in sksg::RadialGradient, and sksg::LinearGradient.

onRevalidate()

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

finalprotectedvirtualinherited

Implements sksg::Node.

onRevalidateShader()

sk_sp<SkShader> sksg::Gradient::onRevalidateShader ( )

finalprotectedvirtual

Implements sksg::Shader.

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.
