InputMerger

Kotlin |Java

abstract class InputMerger

kotlin.Any
↳	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.
