Method Detail

getBeforeAndAfterMapsForChanges

public static Pair<Map<QName,Serializable>,Map<QName,Serializable>> getBeforeAndAfterMapsForChanges(Map<QName,Serializable> before,
                                                                                                    Map<QName,Serializable> after)

Utility method to remove unchanged entries from each map.

Parameters:

before - the properties before (may be null)

after - the properties after (may be null)

Returns:

Return a map of values that changed from before to after. The before value is first and the after value is second.

getAddedProperties

public static Map<QName,Serializable> getAddedProperties(Map<QName,Serializable> before,
                                                         Map<QName,Serializable> after)

Utility method to get properties which were added as part of a change.

Parameters:

before - the properties before (may be null).

after - the properties after (may be null).

Returns:

a map of values that were added along with their new values.

Utility method to get properties which were removed as part of a change.

Parameters:

before - the properties before (may be null).

after - the properties after (may be null).

Returns:

a map of values that were removed along with their old values.

Since:
