public class Macro
extends Directive

Macro.java Macro implements the macro definition directive of VTL. example : #macro( isnull $i ) #if( $i ) $i #end #end This object is used at parse time to mainly process and register the macro. It is used inline in the parser when processing a directive.

static void	processAndRegister(RuntimeServices rs, Node node, String sourceTemplate) Used by Parser.java to process VMs withing the parsing process processAndRegister() doesn't actually render the macro to the output Processes the macro body into the internal representation used by the VelocimacroProxy objects, and if not currently used, adds it to the macro Factory
boolean	render(InternalContextAdapter context, Writer writer, Node node) render() doesn't do anything in the final output rendering.
