Goals

Kripton was built with the following objectives:

• Create provide a simple and coherent way to persist data independently if you want to store data on file, on an SQLite database, on a SharedPreferences or data arrived by REST web service.
• Work at max speed: I want to realize the best (or one of them) persistence library in terms of speed to persist on. You can see benchmarks page to have more information about performance. This is obtained with the use of the annotation processor.
• Support the highest number of possible formats: JSON, XML, YAML, CBOR, (Java) properties, SQLite and SharedPreferences.
• Persist on SQLite in very easy way: for who known SQL and don't like write to write it and boilerplate-code to support it, Kripton IS the right library.

Features

Kripton has some runtime-libraries (for Android platform, for Java platform) and a Java annotation processor library. Annotation processor generates code which is based on runtime libraries: kripton-android-library and kripton-library.

Supported field types

• All primitive types (bool, int, long, float, etc..)
• All simple types (Boolean, String, Byte, Float, Integer, etc..)
• List collections: if you use List interface, an ArrayList will be used.
• Set collections: if you use Set interface, a HashSet will be used.
• Map collections: if you use Map interface, an HashLinkedMap will be used.
• BigDecimal, BigInteger, Calendar, Currency, Locale, Time, TimeZone, Url
• Array collections
• POJO bean type with @BindType annotation
• Virtually every kind of other type thanks to type adapter you can define and use.

Supported persistence formats

Supported persistence methods are:

• data format XML (since 1.0.0)
• data format JSON (since 1.0.0)
• data format YAML (since 1.5.0)
• data fromat CBOR (since 1.5.0)
• data (java) properties (since 1.5.0)
• data format SMILE (since 2.0.0)
• SQLite (since 1.2.0).
• Shared preferences (since 1.2.0).

Supported Languages

• Java
• Kotlin

Platforms

Supported platforms:

• Android 4.x+ (since 1.0.0)
• Generic Java 8 platform (since 5.0.0)

Limits

Kripton has some limitations and constraints:

• No cyclic support: it's not possible to bind object with cyclic references.
• In SQLite tables need to have a long primary key.
• DAOs can extract only fields of the associated table: it's possible to define complex queries, but only associated table's field can be used as a result.
