public interface ExpressionNode
extends javax.xml.transform.SourceLocator
```
A class that implements this interface can construct expressions, give information about child and parent expressions, and give the originating source information. A class that implements this interface does not lay any claim to being directly executable.
Note: This interface should not be considered stable. Only exprSetParent and exprGetParent can be counted on to work reliably. Work in progress.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`exprAddChild(ExpressionNode n, int i)`	This method tells the node to add its argument to the node's list of children.
`ExpressionNode`	`exprGetChild(int i)`	This method returns a child node.
`int`	`exprGetNumChildren()`	Return the number of children the node has.
`ExpressionNode`	`exprGetParent()`
`void`	`exprSetParent(ExpressionNode n)`	This pair of methods are used to inform the node of its parent.

  - exprSetParent
```
void exprSetParent(ExpressionNode n)
```
    This pair of methods are used to inform the node of its parent.
  - exprGetParent
```
ExpressionNode exprGetParent()
```
  - exprAddChild
```
void exprAddChild(ExpressionNode n,
                  int i)
```
    This method tells the node to add its argument to the node's list of children.
  - exprGetChild
```
ExpressionNode exprGetChild(int i)
```
    This method returns a child node. The children are numbered from zero, left to right.
  - exprGetNumChildren
```
int exprGetNumChildren()
```
    Return the number of children the node has.
