com.google.common.css.compiler.ast.CssConstantReferenceNode

All Implemented Interfaces:

Locatable

public class CssConstantReferenceNode
extends CssValueNode

A node holding a reference to a constant or an argument of a mixin definition.

Because references can be valid within one block, each reference has a scope where it is valid. For example, references to arguments of mixin definitions are only valid in the block of the mixin definition whereas references to global definitions are valid everywhere.
