Manage the setup, teardown, and caching of objects of type V safely in a multithreaded environment.

These instances are automatically constructed on-demand from the give key, cached with an LRU strategy, and destroyed when they are eventually evicted

Generic retry functionality

Generic retry functionality

Value parameters

backoffMillis

What is the initial backoff time

backoffMultiplier

How much to multiply the initial backoff each time

count

How many times to retry before giving up

filter

Whether or not we want to retry a given exception at a given retryCount; defaults to true to retry all exceptions, but can be made more fine-grained to only retry specific exceptions, or log them together with the retryCount

logger

Method to log messages upon failure

t

The code block that we want to retry

timeoutMillis

How much time we want to allow t to run. If passed, runs t in a separate thread and throws a TimeoutException if it takes too long

Attributes

Returns

the value of evaluating t, or throws an exception if evaluating t fails more than count times
