Package org.javalite.activeweb.freemarker

Class DebugTag

java.lang.Object

org.javalite.activeweb.freemarker.FreeMarkerTag

org.javalite.activeweb.freemarker.DebugTag

All Implemented Interfaces:

freemarker.template.TemplateDirectiveModel, freemarker.template.TemplateModel, RequestAccess

public class DebugTag
extends FreeMarkerTag

Debug tag is for printing an arbitrary object from page context. FreeMarker special handling of types sometimes makes it hard to see the value(s) of an object, but this tag makes it easy:

 <@debug print=objectname/>
 

For instance, for a `java,util.Map` object it will print this:

     {key1=value1, key2=value2}
