SecondViewModel

The MVVM androidx.lifecycle.ViewModel for the second screen in the MVVM with Process Death demo. Loads the image either from the com.grarcht.shuttle.framework.Shuttle warehouse or from the in-memory com.grarcht.shuttle.demo.processdeath.model.ImageCache, and exposes the result as a StateFlow of SecondImageState.

Functions

addCloseable

open fun addCloseable(closeable: AutoCloseable)

fun addCloseable(key: String, closeable: AutoCloseable)

currentImageModel

fun currentImageModel(): ImageModel?

Returns the com.grarcht.shuttle.demo.core.image.ImageModel from the current SecondImageState.Success state, or null if the image has not been loaded successfully.

getCloseable

fun <T : AutoCloseable> getCloseable(key: String): T?

loadFromMemoryCache

fun loadFromMemoryCache()

Loads the image from the in-memory com.grarcht.shuttle.demo.processdeath.model.ImageCache and updates imageState. Transitions to SecondImageState.LostToProcessDeath if the cache is empty, demonstrating that in-memory state does not survive process death.

loadFromShuttle

fun loadFromShuttle(shuttle: Shuttle, cargoId: String)

Picks up cargo from the com.grarcht.shuttle.framework.Shuttle warehouse using cargoId and updates imageState with the result. Transitions to SecondImageState.LostToProcessDeath immediately when cargoId is empty, indicating that the cargo was not preserved.
