- uk.co.cogitolearning.cogpar.ExponentiationExpressionNode

All Implemented Interfaces:

ExpressionNode
```
public class ExponentiationExpressionNode
extends Object
implements ExpressionNode
```
An ExpressionNode that handles exponentiation. The node holds a base and an exponent and calulates base^exponent

```
public ExponentiationExpressionNode(ExpressionNode base,
                                    ExpressionNode exponent)
```
    Construct the ExponentiationExpressionNode with base and exponent
    
    Parameters:
    
    base - the node containing the base
    
    exponent - the node containing the exponent
- Method Detail
  - getType
```
public int getType()
```
    Returns the type of the node, in this case ExpressionNode.EXPONENTIATION_NODE
    
    Specified by:
    
    getType in interface ExpressionNode
    
    Returns:
    
    type of the node
  - getValue
```
public double getValue()
```
    Returns the value of the sub-expression that is rooted at this node. Calculates base^exponent
    
    Specified by:
    
    getValue in interface ExpressionNode
    
    Returns:
    
    value of expression
  - accept
```
public void accept(ExpressionNodeVisitor visitor)
```
    Implementation of the visitor design pattern. Calls visit on the visitor and then passes the visitor on to the accept method of the base and the exponent.
    
    Specified by:
    
    accept in interface ExpressionNode
    
    Parameters:
    
    visitor - the visitor
