AMB Library documentation outlines the internal classes and structures for building plugins for AMB.
AMB has 3 main parts. Source plugins which provide data, a routing engine that routes data and sink plugins that consume the data.
There are two types of plugins: plugins that provide data, called "sources" (AbstractSource) and plugins that consume data, called "sinks" (AbstractSink). A typical source would get data from the vehicle and then translate the raw data into AMB property types. Sinks then subscribe to the property types and do useful things with the data.
Example plugins can be found in plugins/exampleplugin.{h,cpp} for an example source plugin and plugins/examplesink.{h,cpp} for an example sink plugin. There are also many different types of plugins useful for testing and development in the plugins/ directory.
As of 0.12, the routing engine itself can be exchanged for a plugin. This allows users to swap in routing engines with different behaviors, additional security, and custom throttling and filtering features.
The easiest way to get started creating a routing engine plugin would be to look at AbstractRoutingEngine, the base class for all routing engines and the default routing engine in ambd/core.cpp.
