extends Object

Velocity template engine.

Velocity tools supported (See http://velocity.apache.org/tools/devel/generic.html}:

• DateTool
• ComparisonDateTool
• MathTool
• NumberTool
• SortTool

Examples:

 $dateTool:            $dateTool.get('yyyy-M-d H:m:s')                                 -> 2003-10-19 21:54:50
 
 $dateComparisonTool:  $dateComparisonTool.difference('2005-07-04','2007-02-15').abbr  -> 1 yr
 
 $mathTool:            $mathTool.toNumber($value)                                      -> Converts java.lang.String $value to a java.lang.Number
 
 $numberTool:          $numberTool.currency($myNumber)                                 -> $13.55
 
 $sortTool:            $sorter.sort($collection, "name:asc")                           -> Sorts $collection with property 'name' in ascending order
