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.
