A MicroEJ Foundation Library is a MicroEJ Core library that provides
core runtime APIs or hardware-dependent functionality. A Foundation
library is divided into an API and an implementation. A Foundation
library API is composed of a name and a 2 digits version (e.g.
EDC-1.3) and follows the semantic versioning (http://semver.org)
specification. A Foundation Library API only contains prototypes without
code. Foundation Library implementations are provided by MicroEJ
Platforms. From a MicroEJ Classpath, Foundation Library APIs
dependencies are automatically mapped to the associated implementations
provided by the Platform or the Virtual Device on which the application
is being executed.
A MicroEJ Add-On Library is a MicroEJ library that is implemented on top of MicroEJ Foundation Libraries (100% full Java code). A MicroEJ Add-On Library is distributed in a single JAR file, with a 3 digits version and provides its associated source code.
Foundation and Add-On Libraries are added to MicroEJ Classpath by the application developer as module dependencies (see MicroEJ Module Manager).
MicroEJ Corp. provides a large number of libraries through the MicroEJ Central Repository. To consult its libraries APIs documentation, please visit https://developer.microej.com/microej-apis/.
