public class DollarContext
extends AbstractTemplateFunction

A template parser function for Java attributes. You can use the following syntax: {{#$:object|formatstring|separator|null-value}}. Example:

 public void testRendererForST() throws Exception {
     wikiModel.setAttribute("created", new GregorianCalendar(2005, 07 - 1, 05));
     wikiModel.registerRenderer(GregorianCalendar.class, wikiModel.new DateRenderer());
     String expecting = "date: 2005.07.05";
     assertEquals(expecting, wikiModel.parseTemplates("date: {{#$:created}}"));
 }

 public class DateRenderer implements AttributeRenderer {
     public String toString(Object o) {
         SimpleDateFormat f = new SimpleDateFormat("yyyy.MM.dd");
         return f.format(((Calendar) o).getTime());
     }

     public String toString(Object o, String formatString) {
         return toString(o);
     }
 }

Description copied from class: AbstractTemplateFunction

Parse a template function (like for example {{ #if: ... }}). The result is also a text string in Wikipedia syntax notation which will be parsed again (recursively) in the TemplateParser step.

Specified by:

parseFunction in interface ITemplateFunction

Specified by:

parseFunction in class AbstractTemplateFunction

Parameters:

list - the parser function arguments (extracted from the wiki text by splitting the string at the pipe symbol ´|´)

model - the wiki model

src - the array of the current Wikipedia source text.

beginIndex - the beginning index, inclusive.

endIndex - the ending index, exclusive.

isSubst - if true the template function was called from subst or safesubst function and the arguments of the function are typically not parsed recursively.

Returns:

the result string of this template function or null if the parsing fails or isn't valid.

Throws:

IOException
