valuesMatch

public boolean valuesMatch(PrismContainerValue<?> targetValue,
 PrismContainerValue<?> sourceValue)

Description copied from interface: NaturalKeyDefinition

Returns `true` if the target and source container values match on their natural key. (I.e. they have to be merged/diffed together.)

Specified by:

valuesMatch in interface NaturalKeyDefinition

mergeMatchingKeys

public void mergeMatchingKeys(PrismContainerValue<?> targetValue,
 PrismContainerValue<?> sourceValue)

Source and target paths have to be equivalent here. We assume the source and target paths are purely name-based. We go through them and construct the resulting path from the "most qualified" segments of these. We intentionally ignore some exotic cases here. (We are not obliged to create a "ideal" merged key, anyway.)
