Method Detail

getPriority

public int getPriority(Class<? extends DatabaseObject> objectType,
                       Database database)

Specified by:

getPriority in interface DatabaseObjectComparator

hash

public String[] hash(DatabaseObject databaseObject,
                     Database accordingTo,
                     DatabaseObjectComparatorChain chain)

Specified by:

hash in interface DatabaseObjectComparator

isSameObject

public boolean isSameObject(DatabaseObject databaseObject1,
                            DatabaseObject databaseObject2,
                            Database accordingTo,
                            DatabaseObjectComparatorChain chain)

Specified by:

isSameObject in interface DatabaseObjectComparator

findDifferences

public ObjectDifferences findDifferences(DatabaseObject databaseObject1,
                                         DatabaseObject databaseObject2,
                                         Database accordingTo,
                                         CompareControl compareControl,
                                         DatabaseObjectComparatorChain chain,
                                         Set<String> exclude)

Specified by:

findDifferences in interface DatabaseObjectComparator

undoCollection

protected Object undoCollection(Object potentialCollection,
                                Object otherObject)

Sometimes an attribute in one object is a single-entity collection and on the other it is just the object. Check the passed potentialCollection and if it is a single-entry collection of the same type as the otherObject, return just the collection element. Otherwise, return the original collection.

nameMatches

public static boolean nameMatches(DatabaseObject databaseObject1,
                                  DatabaseObject databaseObject2,
                                  Database accordingTo)
