Gets the matching score for a simple difference. This will return 0 in case both objects are of the same type. If both objects are of a different type, they are less likely to be a best match, so 5 is returned.

参数：

difference - The difference, not null

返回：

The score

getMatchingScore

protected int getMatchingScore(ObjectDifference objectDifference)

Gets the matching score for an object difference. Returns the nr of field differences.

参数：

objectDifference - The difference, not null

返回：

The score

getMatchingScore

protected int getMatchingScore(MapDifference mapDifference)

Gets the matching score for a map difference. Returns the nr of value differences.

参数：

mapDifference - The difference, not null

返回：

The score

getMatchingScore

protected int getMatchingScore(CollectionDifference collectionDifference)

Gets the matching score for a collection difference. Returns the nr of element differences.

参数：

collectionDifference - The difference, not null

返回：

The score

getMatchingScore

protected int getMatchingScore(UnorderedCollectionDifference unorderedCollectionDifference)

Gets the matching score for an unordered collection difference. Returns the sum of the matching scores of the best matches.

参数：

unorderedCollectionDifference - The difference, not null

返回：

The score
