[edit] Description

This extension allows you to add objects which will be accessible during velocity template execution.

[edit] Configuration Markup

<!ELEMENT helper>
 <!ATTLIST helper
    name         CDATA    #REQUIRED
    class        CDATA    #REQUIRED
>

name

name of the variable accessible during template execution. For example, if "test" is specified, then you can refer to it inside the template as $test.

class

fully-qualified name of the class to instantiate. This class must have default constructor. The only one global instance of this class is created for all templates execution, thus it's highly recommended that this class has no internal state.

[edit] Example

<extension id="utils" point="ru.biosoft.templates.contextItem">
  <helper name="utils" class="ru.biosoft.templates.Formatter" />
</extension>

Now an instance of Formatter class will be accessible from any velocity template via $utils variable.
