Package com.google.common.css.compiler.passes

Class ReplaceMixins

java.lang.Object

com.google.common.css.compiler.ast.DefaultTreeVisitor

com.google.common.css.compiler.passes.ReplaceMixins

All Implemented Interfaces:

AtRuleHandler, CssCompilerPass, CssTreeVisitor

public class ReplaceMixins
extends DefaultTreeVisitor
implements CssCompilerPass

Compiler pass that replaces mixins with the corresponding mixin definitions and replaces the variables in the definitions with the values given by the mixin.

In addition, this pass ensures that each mixin has a matching definition and that the argument count of the use and the definition is equal.

CollectMixinDefinitions has to run before. ReplaceConstantReferences has to run afterwards.
