Detailed Description

template<typename T>
class sksg::Matrix< T >

Concrete, matrix-backed Transform.

Supported instantiations: SkMatrix, SkM44.

Sample use:

auto m33 = Matrix<SkMatrix>::Make(SkMatrix::I()); ... m33->setMatrix(SkMatrix::Translate(10, 10));

◆ onRevalidate()

template<typename T >
SkRect sksg::Matrix< T >::onRevalidate ( InvalidationController *  ,
const SkMatrix< T > &   
)
inlineoverrideprotectedvirtual

Implements sksg::Node.

◆ 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.
