Method Details

deferredToMono

public static <T> Mono<T> deferredToMono(kotlinx.coroutines.Deferred<T> source)

Convert a Deferred instance to a Mono.

monoToDeferred

public static <T> kotlinx.coroutines.Deferred<T> monoToDeferred(Mono<T> source)

Convert a Mono instance to a Deferred.

invokeSuspendingFunction

public static Publisher<?> invokeSuspendingFunction(Method method,
 Object target,
 @Nullable Object... args)

Invoke a suspending function and convert it to Mono or Flux. Uses an unconfined dispatcher, augmented with PropagationContextElement if Reactor automatic context propagation is enabled.

Parameters:

method - the suspending function to invoke

target - the target to invoke method on

args - the function arguments. If the Continuation argument is specified as the last argument (typically null), it is ignored.

Returns:

the method invocation result as reactive stream

Throws:

IllegalArgumentException - if method is not a suspending function

invokeSuspendingFunction

public static Publisher<?> invokeSuspendingFunction(kotlin.coroutines.CoroutineContext context,
 Method method,
 @Nullable Object target,
 @Nullable Object... args)

Invoke a suspending function and convert it to Mono or Flux.

Parameters:

context - the coroutine context to use

method - the suspending function to invoke

target - the target to invoke method on

args - the function arguments. If the Continuation argument is specified as the last argument (typically null), it is ignored.

Returns:

the method invocation result as reactive stream

Throws:

IllegalArgumentException - if method is not a suspending function
