Method Detail

jjtAccept

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

Accept the visitor.

Specified by:

jjtAccept in interface Node

jjtAccept in class SimpleNode

Parameters:

visitor - a ParserVisitor.

data - data to be passed along to the visitor.

Gets the value of this node.

Overrides:

value in class SimpleNode

Parameters:

jc - the context to retrieve values from.

Returns:

the value of the node.
