public virtual Java.Util.Concurrent.ICompletionStage? ThenCompose(Java.Util.Functions.IFunction? fn);

[<Android.Runtime.Register("thenCompose", "(Ljava/util/function/Function;)Ljava/util/concurrent/CompletableFuture;", "GetThenCompose_Ljava_util_function_Function_Handler", ApiSince=24)>]
[<Java.Interop.JavaTypeParameters(new System.String[] { "U" })>]
abstract member ThenCompose : Java.Util.Functions.IFunction -> Java.Util.Concurrent.ICompletionStage
override this.ThenCompose : Java.Util.Functions.IFunction -> Java.Util.Concurrent.ICompletionStage

Parameters

fn: IFunction

the function to use to compute another CompletionStage

Returns

ICompletionStage

the new CompletionStage

Implements

ThenCompose(IFunction)

Attributes: RegisterAttribute JavaTypeParametersAttribute

Remarks

Returns a new CompletionStage that is completed with the same value as the CompletionStage returned by the given function. When this stage completes normally, the given function is invoked with this stage's result as the argument, returning another CompletionStage. When that stage completes normally, the CompletionStage returned by this method is completed with the same value. To ensure progress, the supplied function must arrange eventual completion of its result. This method is analogous to Optional.flatMap and Stream.flatMap. See the CompletionStage documentation for rules covering exceptional completion.
