C# Class Spring.Retry.Retry.Backoff.ExponentialBackOffPolicy

Implementation of IBackOffPolicy that increases the back off period for each retry attempt in a given set using the {@link Math#exp(double) exponential} function. This implementation is thread-safe and suitable for concurrent access. Modifications to the configuration do not affect any retry sets that are already in progress. The InitialInterval property controls the initial value passed to {@link Math#exp(double)} and the Multiplier property controls by how much this value is increased for each subsequent attempt.
