InputMerger

Kotlin |Java

public abstract class InputMerger
extends Object

java.lang.Object
↳	androidx.work.InputMerger

Known direct subclasses

ArrayCreatingInputMerger	An `InputMerger` that attempts to merge the inputs, creating arrays when necessary.
OverwritingInputMerger	An `InputMerger` that attempts to add all keys from all inputs to the output.

An abstract class that allows the user to define how to merge a list of inputs to a ListenableWorker.

Before workers run, they receive input Data from their parent workers, as well as anything specified directly to them via WorkRequest.Builder.setInputData(Data). An InputMerger takes all of these objects and converts them to a single merged Data to be used as the worker input. WorkManager offers two concrete InputMerger implementations: OverwritingInputMerger and ArrayCreatingInputMerger.

Note that the list of inputs to merge is in an unspecified order. You should not make assumptions about the order of inputs.
