  - 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.

```
void jjtClose()
```
    This method is called after all the child nodes have been added.
  - jjtSetParent
```

```
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.
