Method Detail

convert

public static <T> Function<Throwable,Mono<T>> convert(String format,
                                                      Object... args)

• NoSuchElementException to IllegalArgumentException

Type Parameters:

T - the type of the Mono being converted

Parameters:

format - A format string

args - Arguments referenced by the format specifiers in the format string. If there are more arguments than format specifiers, the extra arguments are ignored. The number of arguments is variable and may be zero. The maximum number of arguments is limited by the maximum dimension of a Java array as defined by The Java™ Virtual Machine Specification. The behaviour on a null argument depends on the conversion.

Returns:

a function that converts errors
