Interface Summary

Interface	Description
Differ	Engine that can diff two objects and return the results.
DifferenceFilter	Filter that can be applied recursively to a Difference to change the assessment of which Differences are the "same".
ResultSetFilter	Deprecated use DifferenceFilter

Class Summary

Class	Description
DBObjectComparator<T extends DBObject>	Comparator for DBObjects.
DBObjectIDComparator	Comparator for DBObjectIDs
DBObjectIDDiffer	Differ implementation for comparing DBObjectIDs, that optionally executes a strict comparison.
DefaultResultSetFilter	Default implementation of the DifferenceFilter interface, that filters by matching the path to a Difference.
DiffContext
DiffEngine	Engine that can diff two objects and return the results.
Difference	Represents the difference (or comparison) for a given object.
DifferenceApplier	Class that can apply the Difference of two objects recursively.
GenericArrayDiffer	Differ that identifies arrays and uses a list diff to diff them.
GenericBeanDiffer	Differ for any object that uses the PropertyInfos provided by PropertyIterator and diffs the values for those PropertyInfos using the engine.
GenericComparator	Generic comparator for use comparing lists of objects.
GenericDiffEngine	Utility class that sets up a DiffEngine that can generically diff all our DBObjects.
GenericMapDiffer	Differ to diff two maps by key/value pairs.
GenericNameDiffer	Generic differ that only diffs the name of a bean, all other properties are ignored.
GenericToStringDiffer	Differ that will compare two objects if the ToStringManager can convert them to Strings.
IDByNameComparator	Comparator that compares IDs by the name stored on them (if a BaseObjectID) or failing that using the name of the object they resolve to.
IDByNameDiffer	Differ that diffs IDs by the name stored on them (if a BaseObjectID) or failing that using the name of the object they resolve to.
ListDiffer	Differ of lists that uses the Comparators registered with the underlying DiffEngine to compare elements in the two lists to assess whether the contents are different.
OrderedListDiffer	Deprecated ListDiffer has a boolean arg to constructor for order diffing
ResultSet

Package oracle.javatools.db.diff Description

Contains a metadata driven differ of database objects. A DiffEngine can be created and any number of Differ implementations registered with it for comparing objects of different types. The DiffEngine recursively walks down two lists of objects and thier children, diffing objects using the appropiate registered Differs. The result is a complete description of the differences between the two lists and is encapsulated in a ResultSet object.

For comparing lists of objects (including children) that are not naturally sortable, Comparator implementations can be registered against a DiffEngine.

The DiffEngine is not specific to database objects. A number of Differs and Comparators are provided in this package for diffing database objects, ids and associated classes. To provide a proper diff of database objects the GenericDiffEngine class provides a DiffEngine pre-loaded with the appropriate Differ and Comparator objects.
