Method Detail

get

<T> T get(java.util.concurrent.Callable<T> callable)

Executes a Callable with the context of the retry. If the callable throws any exception, then the retryer will handle that according with the configuration the retryer was created.

Type Parameters:

T - type returned by provided Callable

Parameters:

callable - Callable to be executed

Returns:

the output from the callable

run

void run(CheckedRunnable runnable)

Executes a CheckedRunnable with the context of the retry. If the CheckedRunnable throws any exception, then the retryer will handle that according with the configuration the retryer was created.

Parameters:

runnable - CheckedRunnable to be executed

withRetryOn

Retryer withRetryOn(java.util.function.Predicate<java.lang.Throwable> throwablePredicate)

Optional predicates to be evaluated before the retryer implementation runs a retry

Parameters:

throwablePredicate - Predicate to verify against the exceptions thrown on the retry.

Returns:

current retryer, altered

withRetryIf

<T> Retryer withRetryIf(java.util.function.Predicate<T> predicate)

Optional predicates to be compared against the result of the "get" result of a retry. If it matches, will try again.

Type Parameters:

T - type accepted by predicate

Parameters:

predicate - Predicate to verify against the result of the retry.

Returns:

current retryer, altered
