- Methods
  Method | Description
  --- | ---
  org.apache.cayenne.access.DataContext.setTransactionFactory​(TransactionFactory) | since 4.0 avoid using this directly. Transaction management at this level will be eventually removed
  org.apache.cayenne.access.DataDomain.addFilter​(DataChannelFilter) | since 4.1 use `DataDomain.addQueryFilter(DataChannelQueryFilter)` and `DataDomain.addSyncFilter(DataChannelSyncFilter)` instead
  org.apache.cayenne.access.DataDomain.getFilters() | since 4.1 use `DataDomain.getQueryFilters()` and `DataDomain.getSyncFilters()`
  org.apache.cayenne.access.DataDomain.initWithProperties​(Map<String, String>) | since 4.0 properties are processed by the DI provider.
  org.apache.cayenne.access.DataDomain.removeFilter​(DataChannelFilter) | since 4.1 use `DataDomain.removeQueryFilter(DataChannelQueryFilter)` and `DataDomain.removeSyncFilter(DataChannelSyncFilter)` instead
  org.apache.cayenne.access.OperationObserver.nextGeneratedRows​(Query, ResultIterator<?>, ObjectId) | since 4.2, use `OperationObserver.nextGeneratedRows(Query, ResultIterator, List)`
  org.apache.cayenne.cache.NestedQueryCache.clear() | since 4.0
  org.apache.cayenne.cache.QueryCache.clear() | since 4.0. Please use implementation specific methods to perform cache management tasks.
  org.apache.cayenne.CayenneDataObject.makePath​(String...) | since 4.1, use `Cayenne.makePath(String...)` instead

  org.apache.cayenne.dba.AutoAdapter.getSelectTranslator​(SelectQuery<?>, EntityResolver) |
  org.apache.cayenne.dba.DbAdapter.getSelectTranslator​(SelectQuery<?>, EntityResolver) | since 4.2 as `SelectQuery` is deprecated. `DbAdapter.getSelectTranslator(FluentSelect, EntityResolver)` replaces this method.
