Summary

Public methods
`abstract void`	`clearFragmentResult(String requestKey)` Clears the stored result for the given requestKey.
`abstract void`	`clearFragmentResultListener(String requestKey)` Clears the stored `FragmentResultListener` for the given requestKey.
`abstract void`	`setFragmentResult(String requestKey, Bundle result)` Sets the given result for the requestKey.
`abstract void`	`setFragmentResultListener(String requestKey, LifecycleOwner lifecycleOwner, FragmentResultListener listener)` Sets the `FragmentResultListener` for a given requestKey.

Public methods

clearFragmentResult

public abstract void clearFragmentResult (String requestKey)

Clears the stored result for the given requestKey. This clears any result that was previously set via setFragmentResult(String, Bundle) that hasn't yet been delivered to a FragmentResultListener.

Parameters
`requestKey`	`String`: key used to identify the result

clearFragmentResultListener

public abstract void clearFragmentResultListener (String requestKey)

Clears the stored FragmentResultListener for the given requestKey. This clears any FragmentResultListener that was previously set via setFragmentResultListener(String, LifecycleOwner, FragmentResultListener).

Parameters
`requestKey`	`String`: key used to identify the result

setFragmentResult

public abstract void setFragmentResult (String requestKey, 
                Bundle result)

Sets the given result for the requestKey. This result will be delivered to a FragmentResultListener that is called given to setFragmentResultListener(String, LifecycleOwner, FragmentResultListener) with the same requestKey. If no FragmentResultListener with the same key is set or the Lifecycle associated with the listener is not at least Lifecycle.State.STARTED, the result is stored until one becomes available, or clearFragmentResult(String) is called with the same requestKey.

Parameters
`requestKey`	`String`: key used to identify the result
`result`	`Bundle`: the result to be passed to another fragment

setFragmentResultListener

public abstract void setFragmentResultListener (String requestKey, 
                LifecycleOwner lifecycleOwner, 
                FragmentResultListener listener)

Sets the FragmentResultListener for a given requestKey. Once the given LifecycleOwner is at least in the Lifecycle.State.STARTED state, any results set by setFragmentResult(String, Bundle) using the same requestKey will be delivered to the callback. The callback will remain active until the LifecycleOwner reaches the Lifecycle.State.DESTROYED state or clearFragmentResultListener(String) is called with the same requestKey.

Parameters
`requestKey`	`String`: requestKey used to identify the result
`lifecycleOwner`	`LifecycleOwner`: lifecycleOwner for handling the result
`listener`	`FragmentResultListener`: listener for result changes
