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

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

jjtAppendChild

public void jjtAppendChild(Node n)

Description copied from interface: Node

Adds the supplied node as the last child node to this node.

Specified by:
