Class TextDifferenceListenerBase

java.lang.Object

org.custommonkey.xmlunit.examples.TextDifferenceListenerBase

All Implemented Interfaces:

DifferenceListener

Direct Known Subclasses:

CaseInsensitiveDifferenceListener, FloatingPointTolerantDifferenceListener

public abstract class TextDifferenceListenerBase
extends Object
implements DifferenceListener

Base class that delegates all differences to another DifferenceListener.

Subclasses get a chance to hook into special methods that will be invoked for differences in textual values of attributes, CDATA sections, Text or comment nodes.

TextDifferenceListenerBase

protected TextDifferenceListenerBase(DifferenceListener delegateTo)

Creates a new instance

Parameters:

delegateTo - the DifferenceListener to delegate to.

Method Detail

differenceFound

public int differenceFound(Difference difference)

Delegates to the nested DifferenceListener unless the Difference is of type ATTR_VALUE_ID, CDATA_VALUE_ID, COMMENT_VALUE_ID or TEXT_VALUE_ID - for those special differences attributeDifference, cdataDifference, commentDifference or textDifference are invoked respectively.

Specified by:

differenceFound in interface DifferenceListener

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

attributeDifference

protected int attributeDifference(Difference d)

Delegates to textualDifference.

Parameters:

d - the difference

Returns:

int one of the RETURN_... constants describing how this difference was interpreted

cdataDifference

protected int cdataDifference(Difference d)

Delegates to textualDifference.

Parameters:

d - the difference

Returns:

int one of the RETURN_... constants describing how this difference was interpreted

commentDifference

protected int commentDifference(Difference d)

Delegates to textualDifference.

Parameters:

d - the difference

Returns:

int one of the RETURN_... constants describing how this difference was interpreted

textDifference

protected int textDifference(Difference d)

Delegates to textualDifference.

Parameters:

d - the difference

Returns:

int one of the RETURN_... constants describing how this difference was interpreted

textualDifference

protected int textualDifference(Difference d)

Delegates to the nested DifferenceListener.

Parameters:

d - the difference

Returns:

int one of the RETURN_... constants describing how this difference was interpreted

skippedComparison

public void skippedComparison(Node control,
                              Node test)

Description copied from interface: DifferenceListener

Receive notification that a comparison between 2 nodes has been skipped because the node types are not comparable by the DifferenceEngine

Specified by:

skippedComparison in interface DifferenceListener

Parameters:

control - the control node being compared

test - the test node being compared
