Constructor Summary public   ASTIdentifier(int id)      Create the node given an id. public   ASTIdentifier(Parser p, int id)      Create a node with the given parser and id. Method Summary public  Object execute(Object obj, JexlContext jc)      returns the value of itself applied to the object. public  String getIdentifierString()      Gets the name of the variable. public  Object jjtAccept(ParserVisitor visitor, Object data)      public  Object value(JexlContext jc)      Field Detail val protected String val(Code) the name of the variable. Constructor Detail ASTIdentifier public ASTIdentifier(int id)(Code) Create the node given an id. Parameters:   id - node id. ASTIdentifier public ASTIdentifier(Parser p, int id)(Code) Create a node with the given parser and id. Parameters:   p - a parser. Parameters:   id - node id. Method Detail execute public Object execute(Object obj, JexlContext jc) throws Exception(Code) returns the value of itself applied to the object. We assume that an identifier can be gotten via a get(String). e.g. if we have bean.property, 'property' has been parsed as an identifier, and we need to resolve the expression by calling the property getter. Parameters:   obj - the object to evaluate against. Parameters:   jc - the JexlContext. throws:   Exception - on any error. the resulting value.
