|
Method Summary | |
Object |
childrenAccept(ParserVisitor visitor,
Object data)
Accept the visitor. |
void |
dump(String prefix)
|
Object |
execute(Object o,
JexlContext ctx)
Used to let a node calcuate it's value.. |
boolean |
interpret(JexlContext pc)
basic interpret - just invoke interpret on all children |
Object |
jjtAccept(ParserVisitor visitor,
Object data)
Accept the visitor. |
void |
jjtAddChild(Node n,
int i)
This method tells the node to add its argument to the node's list of children. |
void |
jjtClose()
This method is called after all the child nodes have been added. |
Node |
jjtGetChild(int i)
This method returns a child node. |
int |
jjtGetNumChildren()
Return the number of children the node has. |
Node |
jjtGetParent()
|
void |
jjtOpen()
This method is called after the node has been made the current node. |
void |
jjtSetParent(Node n)
This pair of methods are used to inform the node of its parent. |
Object |
setValue(JexlContext context,
Object value)
Sets the value for the node - again, only makes sense for some nodes but lazyness tempts me to put it here. |
String |
toString()
|
String |
toString(String prefix)
|
Object |
value(JexlContext context)
Returns the value of the node. |
