Class TemplateCompactPrintingVisitor<T>

java.lang.Object

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

com.google.common.css.compiler.passes.CompactPrintingVisitor

com.google.common.css.compiler.passes.TemplateCompactPrintingVisitor<T>

Type Parameters:

T - type of chunk id objects

All Implemented Interfaces:

AtRuleHandler, CssTreeVisitor

public class TemplateCompactPrintingVisitor<T>
extends CompactPrintingVisitor

Printer for templates, which outputs GSS with holes to be filled for references. In addition, the declaration boundaries are explicitly noted, so that a declaration can be removed if it ends up empty.

This pass can only be used if MapChunkAwareNodesToChunk pass has been run before. Otherwise this pass won't work.
