Overview

Package module contains application module patterns and associated "manager" functionality. The module pattern has been broken down by:

• independent module functionality (AppModuleBasic)
• inter-dependent module genesis functionality (AppModuleGenesis)
• inter-dependent module full functionality (AppModule)

inter-dependent module functionality is module functionality which somehow depends on other modules, typically through the module keeper. Many of the module keepers are dependent on each other, thus in order to access the full set of module functionality we need to define all the keepers/params-store/keys etc. This full set of advanced functionality is defined by the AppModule interface.

Independent module functions are separated to allow for the construction of the basic application structures required early on in the application definition and used to enable the definition of full module functionality later in the process. This separation is necessary, however we still want to allow for a high level pattern for modules to follow - for instance, such that we don't have to manually register all of the codecs for all the modules. This basic procedure as well as other basic patterns are handled through the use of BasicManager.

Lastly the interface for genesis functionality (AppModuleGenesis) has been separated out from full module functionality (AppModule) so that modules which are only used for genesis can take advantage of the Module patterns without needlessly defining many placeholder functions
