Method Detail
-
jjtOpen
void jjtOpen()
This method is called after the node has been made the current node. It indicates that child nodes can now be added to it.
-
jjtClose
void jjtClose()
This method is called after all the child nodes have been added.
-
jjtSetParent
void jjtSetParent(Node n)
This pair of methods are used to inform the node of its parent.
-
jjtGetParent
Node jjtGetParent()
-
jjtAddChild
void jjtAddChild(Node n, int i)
This method tells the node to add its argument to the node's list of children.
-
jjtGetChild
Node jjtGetChild(int i)
This method returns a child node. The children are numbered from zero, left to right.
-
jjtGetNumChildren
int jjtGetNumChildren()
Return the number of children the node has.
