Package software.amazon.lambda.durable.retry

Interface WaitForConditionWaitStrategy<T>

Type Parameters:
T - the type of state being polled
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface WaitForConditionWaitStrategy<T>
Strategy that computes the delay before the next polling attempt in a waitForCondition operation.

Implementations evaluate the current state and attempt number to compute a Duration delay. The continue/stop decision is handled separately by WaitForConditionResult. When the maximum number of attempts is exceeded, the strategy should throw a WaitForConditionFailedException.
