Description copied from interface: Node
This method is called after the node has been made the current node. It indicates that child nodes can now be added to it.

Specified by:
jjtOpen in interface Node

jjtClose

public void jjtClose()
Description copied from interface: Node
This method is called after all the child nodes have been added.

Specified by:
jjtClose in interface Node

jjtSetParent

public void jjtSetParent(Node n)
Description copied from interface: Node
This pair of methods are used to inform the node of its parent.

Specified by:
jjtSetParent in interface Node

jjtGetParent

public Node jjtGetParent()
Specified by:
jjtGetParent in interface Node

jjtAddChild

public void jjtAddChild(Node n,
                        int i)
Description copied from interface: Node
This method tells the node to add its argument to the node's list of children.

Specified by:
jjtAddChild in interface Node

jjtGetChild

public Node jjtGetChild(int i)
Description copied from interface: Node
This method returns a child node. The children are numbered from zero, left to right.

Specified by:
