Method Detail

onErrorDropped

public static void onErrorDropped(java.util.function.Consumer<? super java.lang.Throwable> c)

Override global error dropped strategy which by default bubble back the error.

Parameters:

c - the dropped error Consumer hook

onNextDropped

public static void onNextDropped(java.util.function.Consumer<java.lang.Object> c)

Override global data dropped strategy which by default throw Exceptions.failWithCancel()

Parameters:

c - the dropped next Consumer hook

onOperator

public static <T> void onOperator(java.util.function.Function<? super Hooks.OperatorHook<T>,? extends Hooks.OperatorHook<T>> newHook)

Set a global "assembly" hook to intercept signals produced by the passed Publisher (Flux or Mono). The passed function must result in a value different from null, and Hooks.OperatorHook.ignore() can be used to discard a specific Publisher from transformations.

Can be reset via resetOnOperator()

Type Parameters:

T - the arbitrary assembled sequence type

Parameters:

newHook - a callback for each assembly that must return a SignalPeek

onOperatorError

public static void onOperatorError(java.util.function.BiFunction<? super java.lang.Throwable,java.lang.Object,? extends java.lang.Throwable> f)

Override global operator error mapping which by default add as suppressed exception either data driven exception or error driven exception.

Parameters:

f - the operator error BiFunction mapper, given the failure and an eventual original context (data or error) and returning an arbitrary exception.

resetOnErrorDropped

public static void resetOnErrorDropped()

Reset global error dropped strategy to bubbling back the error.

resetOnNextDropped

public static void resetOnNextDropped()

Reset global data dropped strategy to throwing via Exceptions.failWithCancel()

resetOnOperator

public static void resetOnOperator()

Reset global "assembly" hook tracking

resetOnOperatorError

public static void resetOnOperatorError()

Reset global operator error mapping to adding as suppressed exception either data driven exception or error driven exception.
