Package dev.amp.validator.visitor

Class SelectorVisitor

java.lang.Object

dev.amp.validator.visitor.SelectorVisitor

All Implemented Interfaces:

RuleVisitor

Direct Known Subclasses:

SelectorSpecVisitor

public abstract class SelectorVisitor
extends Object
implements RuleVisitor

A super class for making visitors (by overriding the types of interest). The standard RuleVisitor does not recursively parse the prelude of qualified rules for the components of a selector. This visitor re-parses these preludes and then visits the fields within. The parse step has the possibility of emitting new CSS ErrorTokens
