plugin_modules.py

This module has the implementation of the plugin module base class from where the rest of the plugin classes are derived.

Classes

  • PluginModule: Base class that implements the plugin architecture. All direct
class infocentre_data_manager.plugins.plugin_module.PluginModule

Base class that implements the plugin architecture. All direct subclasses of this module represent different stages and they have a factory method that scans their directory (e.g. codecs, data_validators, …) and instantiates a particular subsubclass (e.g. ExcelCodec) with only their name (e.g. ‘excel’). For new plugins of a particular type this doesn’t require any imports; this class automatically scans the directory for suitable modules and classes.
