Learn Agera for Android with Examples

Observable, Updatable, Supplier, Receiver

The foundation of Agera is a set of very simple interfaces including: Observable, Updatable, Supplier and Receiver:

• Observable => Something that can be observed for changes and stores a list of updatable objects. When a change occurs, the updatables are poked

• Updatable => Called when an event has occurred. Its update() method will be called when the class it observes changes, but can also be called manually to force an update.

• Supplier => Something that supplies data when the get() method is called. In this case, "Data" can be anything.

• Receiver => Something that can receive (and normally store) a value send to it via accept().

• Repository => The most important concept in Agera is the Repository. Repositories receive, supply, and store data and emit updates. The interfaces Observable, Supplier and Receiver are combined into two types of repositories:

    Repository can replace Observable and Supplier
    MutableRepository can replace Observable, Supplier and Receiver
  

This replacement is shown in Agera-Repositories project.
