Description copied from class: AbstractDirective

Implementations of this method should prepare the TemplatingElement with the known parameters. If parameters have been grabbed using the methods provided by this class, they should be removed from the map, thus leaving an empty map once the method returns. AbstractDirective.execute(freemarker.core.Environment, java.util.Map, freemarker.template.TemplateModel[], freemarker.template.TemplateDirectiveBody) will throw a TemplateModelException if there are leftover parameters.

note: The current FreeMarker implementation passes a "new" Map which we can safely manipulate. is thrown away after the execution of the directive. When no parameters are passed, the Map is readonly, but it is otherwise a regular HashMap which has been instantiated shortly before the execution of the directive. However, since this behavior is not mandated by their API, nor documented (at the time of writing, with FreeMarker 2.3.16), we should exert caution. Unit tests hopefully cover this, so we'll be safe when updating to newer FreeMarker versions.
