Class Parse

java.lang.Object
  extended by org.apache.velocity.runtime.directive.Directive
      extended by org.apache.velocity.runtime.directive.InputBase
          extended by org.apache.velocity.runtime.directive.Parse
All Implemented Interfaces:
Cloneable, DirectiveConstants

public class Parse
extends InputBase

Pluggable directive that handles the #parse() statement in VTL.

 Notes:
 -----
  1) The parsed source material can only come from somewhere in
    the TemplateRoot tree for security reasons. There is no way
    around this.  If you want to include content from elsewhere on
    your disk, use a link from somwhere under Template Root to that
    content.

  2) There is a limited parse depth.  It is set as a property
    "parse_directive.maxdepth = 10"  for example.  There is a 20 iteration
    safety in the event that the parameter isn't set.
