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

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:
