API reference

NOTE This library is available to the public but it's mostly used internally at AVSystem. Therefore, API may frequently change in an incompatible way.

Modules and features

• commons-core - basic language utilities and generic features not associated with any particular library of framework:
  • GenCodec: format-agnostic, typeclass based serialization framework with automatic typeclass derivation for case classes and sealed hierarchies
    • built-in serialization formats include JSON (raw string), CBOR and BSON (in commons-mongo).
  • Typesafe RPC/proxy framework used in particular by Udash Framework for client-server communication
  • Better enumeration support for Scala - ValueEnum, SealedEnumCompanion, NamedEnumCompanion, OrderedEnum
  • Java interoperability utilities - JavaInterop
  • Google Guava interoperability utilities (dependency on Guava is optional)
  • Various Scala language-level utilities
    • Implicit source information objects - SourceInfo
    • More concise aliases for Scala collection types - CollectionAliases
    • Universal extension methods - SharedExtensions
  • Lightweight alternatives for Scala Option - Opt - guarantees no nulls, OptArg, NOpt, OptRef (implemented as value classes)
• commons-redis - Scala driver for Redis
• commons-akka - Akka utilities, primarily AkkaRPCFramework which supports methods returning Monix Observables
• commons-macros contains implementations of macros used in other modules and reusable macro utilities:
  • MacroCommons trait with several convenience functions for implementing macros
  • TypeClassDerivation - implements infrastructure for automatic type class derivation
• commons-analyzer - static analyzer for Scala code, i.e. a compiler plugin that enforces various (mostly unrelated) rules and conventions on source code
• commons-jetty - Jetty server utilities
• commons-mongo - MongoDB utilities for Scala & Java MongoDB drivers, integration with GenCodec
• commons-hocon - Utilities for working with HOCON
  • HoconInput - an Input implementation for GenCodec that can read Lightbend Config (com.typesafe.config.Config)
  • An AST (HTree) and a lexer/parser for HOCON (HLexer, HParser)
• commons-spring - Spring framework utilities:
  • HoconBeanDefinitionReader - an utility that allows you to define Spring application context using HOCON format
