Constructor Detail

AnchorFreeMarkerDirective

public AnchorFreeMarkerDirective(String directiveName,
                         RenderService renderService)

Instantiates a new AnchorFreeMarkerDirective. The RenderService will be used by calling its generateAnchorLink method to generate the output. The directive name is only needed for generating useful exception messages to assist debugging problems but an effort should be made to set it correctly

Parameters:

directiveName - The name of the directive represented by the instance of this class.

renderService - A RenderService used to generate the output of the directive.

Method Detail

execute

public void execute(freemarker.core.Environment env,
           Map params,
           freemarker.template.TemplateModel[] loopVars,
           freemarker.template.TemplateDirectiveBody body)
             throws freemarker.template.TemplateException,
                    IOException

This method is implemented to satisfy the TemplateDirectiveModel interface that is implemented by the AbstractFreeMarkerDirective in the class hierarchy. It retrieves the any parameters that have been supplied when invoking the directive and passes them onto the PresentationService to render the HTML anchor which is then output.

Throws:

freemarker.template.TemplateException

IOException
