Should be something like $. A literal string. render public boolean render(InternalContextAdapter context, Writer writer) throws IOException, MethodInvocationException(Code) gets the value of the reference and outputs it to the writer. Parameters:   context - context of data to use in getting value Parameters:   writer - writer to render to True if rendering was successful. throws:   IOException - throws:   MethodInvocationException - setLiteral public void setLiteral(String literal)(Code) Routine to allow the literal representation to be externally overridden. Used now in the VM system to override a reference in a VM tree with the literal of the calling arg to make it work nicely when calling arg is null. It seems a bit much, but does keep things consistant. Note, you can only set the literal once... Parameters:   literal - String to render to when null setValue public boolean setValue(InternalContextAdapter context, Object value) throws MethodInvocationException(Code) Sets the value of a complex reference (something like $foo.bar) Currently used by ASTSetReference() See Also:   ASTSetDirective Parameters:   context - context object containing this reference Parameters:   value - Object to set as value true if successful, false otherwise throws:   MethodInvocationException - value public Object value(InternalContextAdapter context) throws MethodInvocationException(Code) See Also:   org.apache.velocity.runtime.parser.node.SimpleNode.value(org.apache.velocity.context.InternalContextAdapter) Fields inherited from org.apache.velocity.runtime.parser.node.SimpleNode protected Node[] children(Code)(Java Doc) protected Token first(Code)(Java Doc) protected int id(Code)(Java Doc) protected int info(Code)(Java Doc) protected boolean invalid(Code)(Java Doc) protected Token last(Code)(Java Doc) protected Log log(Code)(Java Doc) protected Node parent(Code)(Java Doc) protected Parser parser(Code)(Java Doc) protected RuntimeServices rsvc(Code)(Java Doc) public boolean state(Code)(Java Doc) Methods inherited from org.apache.velocity.runtime.parser.node.SimpleNode public Object childrenAccept(ParserVisitor visitor, Object data)(Code)(Java Doc) public void dump(String prefix)(Code)(Java Doc) public boolean evaluate(InternalContextAdapter context) throws MethodInvocationException(Code)(Java Doc) public Object execute(Object o, InternalContextAdapter context) throws MethodInvocationException(Code)(Java Doc) public int getColumn()(Code)(Java Doc) public Token getFirstToken()(Code)(Java Doc) public int getInfo()(Code)(Java Doc) public Token getLastToken()(Code)(Java Doc) public int getLine()(Code)(Java Doc) public int getType()(Code)(Java Doc) public Object init(InternalContextAdapter context, Object data) throws TemplateInitException(Code)(Java Doc) public boolean isInvalid()(Code)(Java Doc) public Object jjtAccept(ParserVisitor visitor, Object data)(Code)(Java Doc) public void jjtAddChild(Node n, int i)(Code)(Java Doc) public void jjtClose()(Code)(Java Doc) public Node jjtGetChild(int i)(Code)(Java Doc) public int jjtGetNumChildren()(Code)(Java Doc) public Node jjtGetParent()(Code)(Java Doc) public void jjtOpen()(Code)(Java Doc) public void jjtSetParent(Node n)(Code)(Java Doc) public String literal()(Code)(Java Doc) public boolean render(InternalContextAdapter context, Writer writer) throws IOException, MethodInvocationException, ParseErrorException, ResourceNotFoundException(Code)(Java Doc) public void setFirstToken(Token t)(Code)(Java Doc) public void setInfo(int info)(Code)(Java Doc) public void setInvalid()(Code)(Java Doc) public String toString(String prefix)(Code)(Java Doc) public String toString()(Code)(Java Doc) public Object value(InternalContextAdapter context) throws MethodInvocationException(Code)(Java Doc) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
