Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`int`	`differenceFound(Difference difference)` Receive notification that 2 nodes are different.
`void`	`skippedComparison(Node control, Node test)` Receive notification that a comparison between 2 nodes has been skipped because the node types are not comparable by the DifferenceEngine

- Field Detail
  - RETURN_ACCEPT_DIFFERENCE
```
static final int RETURN_ACCEPT_DIFFERENCE
```
    Standard return value for the differenceFound method. Indicates that the Difference is interpreted as defined in DifferenceConstants.

  - RETURN_IGNORE_DIFFERENCE_NODES_IDENTICAL
```
static final int RETURN_IGNORE_DIFFERENCE_NODES_IDENTICAL
```
    Override return value for the differenceFound method. Indicates that the nodes identified as being different should be interpreted as being identical.

  - RETURN_IGNORE_DIFFERENCE_NODES_SIMILAR
```
static final int RETURN_IGNORE_DIFFERENCE_NODES_SIMILAR
```
    Override return value for the differenceFound method. Indicates that the nodes identified as being different should be interpreted as being similar.

  - differenceFound
```
int differenceFound(Difference difference)
```
    Receive notification that 2 nodes are different.
    
    Parameters:
    
    difference - a Difference instance as defined in DifferenceConstants describing the cause of the difference and containing the detail of the nodes that differ
    
    Returns:
    
    int one of the RETURN_... constants describing how this difference was interpreted
  - skippedComparison
```
void skippedComparison(Node control,
                       Node test)
```
    Receive notification that a comparison between 2 nodes has been skipped because the node types are not comparable by the DifferenceEngine
    
    Parameters:
    
    control - the control node being compared
    
    test - the test node being compared
