Class SelectorMatcher

java.lang.Object

org.eclipse.e4.ui.css.core.impl.engine.selector.SelectorMatcher

public final class SelectorMatcher
extends Object

Matches a Selectors.Selector against an Element.

Every method is static; the matcher carries no state. Callers pass the element being tested plus an optional pseudo-element string (the same argument the SAC engine carried) so that pseudo-class matching can defer to the existing CSSStylableElement.isPseudoInstanceOf(String) contract.

Tag-name comparison is case sensitive, matching the existing SAC matcher (Phase 1 test testTagNameCaseSensitivity in CSSEngineTest locks this in). Pseudo-class semantics also follow the existing engine: the static-pseudo-instance carve-out from CSSPseudoClassConditionImpl is preserved so cascade behaviour does not shift.
