Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`evaluate(Context context)`
`void`	`jjtAddChild(Node n, int i)`	This method tells the node to add its argument to the node's list of children.
`Node`	`jjtGetChild(int i)`	This method returns a child node.
`int`	`jjtGetNumChildren()`	Return the number of children the node has.
`Node`	`jjtGetParent()`
`void`	`jjtSetParent(Node n)`	This pair of methods are used to inform the node of its parent.

- Method Detail
  - 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.
  - evaluate
```
void evaluate(Context context)
```
