Class JSTemplateCompiler

java.lang.Object

to.etc.template.JSTemplateCompiler

public class JSTemplateCompiler
extends Object

This factory class creates a compiled template for a JSP like template. The language is Javascript, using JDK 6 scripting engine. The template's data is copied verbatim to output until a <% or <%= is found; from there it assumes the code is Javascript. The engine first creates a Javascript program from the code entered, then it compiles it into the JSTemplate.
