Method Detail

compareHomes

public static DifferenceBetweenHomes compareHomes(AdaptationHome leftHome,
                                                  AdaptationHome rightHome,
                                                  boolean isResolvedMode)

Compares two homes and returns the result.

Parameters:

leftHome - home on left to use for comparison.

rightHome - home on right to use for comparison.

isResolvedMode - if true, comparison is based on the resolved view (for example if two values are inherited and different, then it is considered as a difference); if false, comparison is made only on defined values (for example if two values are inherited then they are not different because they are both equal to AdaptationValue.INHERIT_VALUE).

compareInstances

public static DifferenceBetweenInstances compareInstances(Adaptation instanceOnLeft,
                                                          Adaptation instanceOnRight,
                                                          boolean isResolvedMode)

Performs a comparison between two instances.

Parameters:

instanceOnLeft - instance on left to use for comparison.

instanceOnRight - instance on right to use for comparison.

isResolvedMode - if true, comparison is based on the resolved view (for example if two values are inherited and different, then it is considered as a difference); if false, comparison is made only on defined values (for example if two values are inherited then they are not different because they are both equal to AdaptationValue.INHERIT_VALUE).

compareTables

public static DifferenceBetweenInstances compareTables(AdaptationTable tableOnLeft,
                                                       AdaptationTable tableOnRight,
                                                       boolean isResolvedMode)

Performs a comparison between two tables.

Parameters:

tableOnLeft - table on left to use for comparison.

tableOnRight - table on right to use for comparison.

isResolvedMode - if true, comparison is based on the resolved view (for example if two values are inherited and different, then it is considered as a difference); if false, comparison is made only on defined values (for example if two values are inherited then they are not different because they are both equal to AdaptationValue.INHERIT_VALUE).

compareOccurrences

public static DifferenceBetweenOccurrences compareOccurrences(Adaptation occurrenceOnLeft,
                                                              Adaptation occurrenceOnRight,
                                                              boolean isResolvedMode)

Performs a comparison between two occurrences.

This method is equivalent to compareOccurrences(occurrenceOnLeft, occurrenceOnRight, isResolvedMode, false). That is, it does show details on terminal complex nodes.

Parameters:

occurrenceOnLeft - occurrence on left to use for comparison.

occurrenceOnRight - occurrence on right to use for comparison.

isResolvedMode - if true, comparison is based on the resolved view (for example if two values are inherited and different, then it is considered as a difference); if false, comparison is made only on defined values (for example if two values are inherited then they are not different because they are both equal to AdaptationValue.INHERIT_VALUE).

compareOccurrences

public static DifferenceBetweenOccurrences compareOccurrences(Adaptation occurrenceOnLeft,
                                                              Adaptation occurrenceOnRight,
                                                              boolean isResolvedMode,
                                                              boolean showDetails)

Performs a comparison between two occurrences.

Parameters:

occurrenceOnLeft - occurrence on left to use for comparison.

occurrenceOnRight - occurrence on right to use for comparison.

isResolvedMode - if true, comparison is based on the resolved view; if false, comparison is made only on defined values (not inherited ones).

showDetails - if true, differences in terminal complex nodes are detailed; if false, comparison stops on terminal node elements even they are complex.
