Method Summary

Modifier and Type	Method and Description
void	setCancelled() Indicate that the invocation was cancelled.
void	setException(Exception exception) Indicate that the invocation failed.
void	setResult(AsynchronousInterceptor.ResultSupplier resultSupplier) Indicate that the invocation is complete, and that the result can be read from the given supplier.
default AsynchronousInterceptor.ResultHandler	withAction(Runnable action) Create a new result handler that delegates to this one but first performs an action.
default <T> AsynchronousInterceptor.ResultHandler	withAction(T argument, Consumer<T> action) Create a new result handler that delegates to this one but first performs an action.
default <T,U> AsynchronousInterceptor.ResultHandler	withAction(T arg1, U arg2, BiConsumer<T,U> action) Create a new result handler that delegates to this one but first performs an action.

withAction

default <T> AsynchronousInterceptor.ResultHandler withAction(T argument,
                                                             Consumer<T> action)

Create a new result handler that delegates to this one but first performs an action.

Parameters:

argument - the argument to pass to action

action - the action to run (must not be null)

Returns:

the new result handler (not null)

withAction

default AsynchronousInterceptor.ResultHandler withAction(Runnable action)
