Xmartlabs Fountain Versions Save

• Upgrade kotlin version to 1.3 and coroutines version to 1.0.1.
• Upgrade Android target version to 28

Big Breaking changes:

Fountain modules

The library now has 3 different modules:

• Coroutine module: Uses a Coroutine Retrofit adapter to fetch the pages.
• Retrofit module: Uses a simple Retrofit call to fetch the pages.
• RxJava2 module: Uses a RxJava2 Retrofit adapter to fetch the pages.

These modules are independent and none of them are strictly required. The new dependencies are:

repositories {
    maven { url "https://jitpack.io" }
}

dependencies {
    // This dependency is required only if you want to use a Retrofit service without a special adapter. 
    implementation 'com.github.xmartlabs.fountain:fountain-retrofit:0.4.0'

    // This dependency is required only if you want to use a Coroutine retrofit adapter.
    implementation 'com.github.xmartlabs.fountain:fountain-coroutines:0.4.0'

    // This dependency is required only if you want to use a RxJava2 retrofit adapter.
    implementation 'com.github.xmartlabs.fountain:fountain-rx2:0.4.0'
}

Not paged endpoint support

Although Fountain was designed to work with paged endpoints, it also supports working with not paged endpoints. That means that you can use all [Listing] features in services that return a list that's not paged.

Factory constructors

There's one static factory object class for each each dependency.

• FountainCoroutines: Used to get a [Listing] from a Retrofit service which uses a Coroutine adapter.
• FountainRetrofit: Used to get a [Listing] from a Retrofit service without using a special adapter.
• FountainRx: Used to get a [Listing] from a Retrofit service which uses a RxJava2 adapter.

Each static factory has the same constructors with different params:

• createNetworkListing: A constructor to get a Listing component from a common paged Retrofit service implementation.
• createNotPagedNetworkListing: A constructor to get a Listing component from a common not paged Retrofit service implementation.
• createNetworkWithCacheSupportListing: A constructor to get a Listing component with cache support from a common paged Retrofit service implementation.
• createNotPagedNetworkWithCacheSupportListing: A constructor to get a Listing component with cache support from a common not paged Retrofit service implementation.

NetworkDataSourceAdapter creators

If you use either ListResponseWithPageCount or ListResponseWithEntityCount you can convert a PageFetcher to a NetworkDataSourceAdapter using these extensions:

fun <ServiceResponse : ListResponseWithEntityCount<*>>
    PageFetcher<ServiceResponse>.toTotalEntityCountNetworkDataSourceAdapter(firstPage: Int)
fun <ServiceResponse : ListResponseWithPageCount<*>>
    PageFetcher<ServiceResponse>.toTotalPageCountNetworkDataSourceAdapter(firstPage: Int)

To more about these changes you can read the full documentation here.

Improve NetworkState structure #28. Now that structure has the requested page number, pageSize, isFirstPage, isLastPage.

Breaking changes: The NetworkState data class is replaced by a sealed class and the Status enum was removed.

Breaking changes:

• Added the possibility of using different models on Network and DataSource sources. Fountain.createNetworkWithCacheSupportListing now requires two type declarations #28.

Fixes:

• Fix issue when the initialization process throws an Exception #29.
