Field Detail

### directive

    private Directive directive

### directiveName

    private java.lang.String directiveName

### isDirective

    private boolean isDirective

Constructor Detail

### ASTDirective

    public ASTDirective(int id)

### ASTDirective

    public ASTDirective(Parser p,
                        int id)

Method Detail

### jjtAccept

    public java.lang.Object jjtAccept(ParserVisitor visitor,
                                      java.lang.Object data)

  Accept the visitor.
  Overrides:

### init

    public java.lang.Object init(InternalContextAdapter context,
                                 java.lang.Object data)
                          throws java.lang.Exception

  Overrides:
    `init` in class `SimpleNode`

### render

    public boolean render(InternalContextAdapter context,
                          java.io.Writer writer)
                   throws java.io.IOException,
                          MethodInvocationException,
                          ResourceNotFoundException,
                          ParseErrorException

  Overrides:
    `render` in class `SimpleNode`

### setDirectiveName

    public void setDirectiveName(java.lang.String str)

  Sets the directive name. Used by the parser. This keeps us from having to dig it out of the token stream and gives the parse the change to override.

### getDirectiveName

    public java.lang.String getDirectiveName()

  Gets the name of this directive.
