Method Detail

jjtAccept

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

Accept the visitor.

Overrides:

jjtAccept in class SimpleNode

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.
