Method Details

enterDefinition

public boolean enterDefinition(CssDefinitionNode node)

Specified by:

enterDefinition in interface AtRuleHandler

Overrides:

enterDefinition in class DefaultTreeVisitor

Parameters:

node - node

Returns:

true if the contents of the rule should be visited, false otherwise. AtRuleHandler.leaveDefinition(CssDefinitionNode) will still be called.

enterValueNode

public boolean enterValueNode(CssValueNode node)

Description copied from interface: CssTreeVisitor

Called before visiting a CssValueNode that is not a CssCompositeValueNode

Specified by:

enterValueNode in interface CssTreeVisitor

Overrides:

enterValueNode in class DefaultTreeVisitor

enterArgumentNode

public boolean enterArgumentNode(CssValueNode node)

Description copied from interface: CssTreeVisitor

Called before visiting a CssFunctionNode's sub trees

Specified by:

enterArgumentNode in interface CssTreeVisitor

Overrides:

enterArgumentNode in class DefaultTreeVisitor

runPass

public void runPass()

Specified by:

runPass in interface CssCompilerPass
