Parameters:

node - node

leaveUnknownAtRule

public void leaveUnknownAtRule(CssUnknownAtRuleNode node)

Description copied from interface: AtRuleHandler

Called after visiting a CssUnknownAtRuleNode's sub trees

Specified by:

leaveUnknownAtRule in interface AtRuleHandler

Overrides:

leaveUnknownAtRule in class DefaultTreeVisitor

enterRuleset

public boolean enterRuleset(CssRulesetNode node)

Description copied from interface: CssTreeVisitor

Called before visiting a CssRulesetNode's sub trees.

Specified by:

enterRuleset in interface CssTreeVisitor

Overrides:

enterRuleset in class DefaultTreeVisitor

Returns:

whether ruleset children should be visited

enterDefinition

public boolean enterDefinition(CssDefinitionNode node)

Specified by:

enterDefinition in interface AtRuleHandler
