public Interface IntervalFunction

Additional top-level class in compilation unit: IntervalFunctionCompanion.

extends Function<Integer, Long>
Annotations
@FunctionalInterface
Imports
java.time.Duration, java.util.function.Function, java.util.stream.LongStream
An IntervalFunction which can be used to calculate the wait interval. The input parameter of the function is the number of attempts (attempt), the output parameter the wait interval in milliseconds. The attempt parameter starts at 1 and increases with every further attempt.
