InputMerger

public abstract class InputMerger
extends Object

java.lang.Object
   ↳ androidx.work.InputMerger


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.
