移動數據庫引擎Realm Java v3.1.0 發布

Realm 是一個跨平臺的移動數據庫引擎，可運行于手機、平板和可穿戴設備之上。于 2014 年 7 月發布，準確來說，它是專門為移動應用所設計的數據持久化解決方案之一。 Realm 可以輕松地移植到您的項目當中，并且絕大部分常用的功能（比如說插入、查詢等等）都可以用一行簡單的代碼輕松完成！ Realm 并不是對 Core Data 的簡單封裝，相反地， Realm 并不是基于 Core Data ，也不是基于 SQLite 所構建的。它擁有自己的數據庫存儲引擎，可以高效且快速地完成數據庫的構建操作。

更新日志

• Updated file format of Realm files. Existing Realm files will automatically be migrated to the new format when they are opened, but older versions of Realm cannot open these files.
• [ObjectServer] Due to file format changes, Realm Object Server 1.3.0 or later is required.
• Added support for reverse relationships through the @LinkingObjects annotation. Seeio.realm.annotations.LinkingObjects for documentation.
• This feature is in @Beta.
• Queries on linking objects do not work. Queries like where(...).equalTo("field.linkingObjects.id", 7).findAll() are not yet supported.
• Backlink verification is incomplete. Evil code can cause native crashes.
• The listener on RealmObject will only be triggered if the object changes (#3894).
• Added RealmObjectChangeListener interface that provide detailed information about RealmObject field changes.
• Listeners on RealmList and RealmResults will be triggered immediately when the transaction is committed on the same thread (#4245).
• The real RealmMigrationNeededException is now thrown instead of IllegalArgumentException if no migration is provided for a Realm that requires it.
• RealmQuery.distinct() can be performed on unindexed fields (#2285).
• targetSdkVersion is now 25.
• [ObjectServer] In case of a Client Reset, information about the location of the backed up Realm file is now reported through the ErrorHandler interface (#4080).

• Realm.migrateRealm(RealmConfiguration) now fails correctly with an IllegalArgumentException if aSyncConfiguration is provided (#4075).
• Fixed a potential cause for Realm file corruptions (never reported).
• Add @Override annotation to proxy class accessors and stop using raw type in proxy classes in order to remove warnings from javac (#4329).
• findFirstAsync() now returns an invalid object if there is no object matches the query condition instead of running the query repeatedly until it can find one (#4352).
• [ObjectServer] Changing the log level after starting a session now works correctly (#4337).
