Class Documentation

struct donner::css::ComplexSelector::Entry

A single entry in a complex selector, which is a compound selector and a combinator.

Collaboration diagram for donner::css::ComplexSelector::Entry:

Class Members
Combinator	combinator	The combinator between this compound selector and the next. For regular selector lists, the first entry is set to Combinator::Descendant but it has no effect. For relative selector lists, the first entry is the leading combinator, for example "> div".
CompoundSelector	compoundSelector	The compound selector.

bool donner::css::ComplexSelector::isValid ( ) const

Return true if this selector is valid and supported by this implementation.

template<ElementLike T>

SelectorMatchResult donner::css::ComplexSelector::matches	(	const T &	targetElement,
		const SelectorMatchOptions< T > &	options ) const

inline

Match a selector against an element, following the rules in the spec: https://www.w3.org/TR/selectors-4/#match-against-element.

Template Parameters

T	A type that fulfills the ElementLike concept, to enable traversing the tree to match the selector.

Parameters

targetElement	Element to match against.
options	Options to control matching.

Returns: true if the element matches the selector, within a SelectorMatchResult which also contains the specificity.
