25 | * The main class to represent a feature in the feature-control library. A feature receives an input
26 | * model (typically from a data source such as a network call), and converts it into a list of items
27 | * that will be displayed inside the recycler view. Items can be of different types and rendered
28 | * using different views. Each item of the list will use its own output model, a partial
29 | * representation of the input model that is of interest to its associated view.
30 | *
31 | * Example: Let's consider the input model class
32 | *
33 | *
34 | * class Foo {
35 | * String title;
36 | * String currency;
37 | * String price;
38 | * }
39 | *
40 | *
41 | * To represent this input model class in feature-adapter, we could create as many different feature
42 | * controllers as we want. Each of them could be in charge of representing one or more field, and/or
43 | * one or more computed values from this input model (like the price in various different
44 | * currencies, or the amount of taxes, etc..). We could have for instance a feature controller that
45 | * represents the title, with items of type String. And a feature controller that represents the
46 | * price and the currency together, using a new output model, a simple pojo with 2 strings or it
47 | * could represent the price and the currency as separate items and use different views to represent
48 | * them.
49 | *
50 | * Note on optimizations: In some cases, some features which are very computation intensive might
51 | * want to avoid building their feature items list as a whole, which will save a lot of computation
52 | * (the creation of the list of feature items and their comparison). In this case, it is recommended
53 | * that a {@code FeatureController} stores the information about the last computed state and
54 | * compares it with the new state inside {@code {@link #buildItems(Object)}}. This comparison is
55 | * really optional and we introduce it here as an optimization mechanism.
56 | *
57 | * @param the class of the input model that this controller will represent partially.
