retryable

public static <U,
V> Function<U,V> retryable(Function<U,V> base,
 Class<? extends Throwable> exceptionClass,
 int maxRetries,
 int maxDelayBetweenRetries)

Returns a function that retries execution on failure.

Type Parameters:

U - type of function input

V - type of function output

Parameters:

base - base function

exceptionClass - type of exception for which to retry

maxRetries - max number of retries before giving up

maxDelayBetweenRetries - max delay between successive retries. The actual delay is randomly picked from the interval (0, maxDelayBetweenRetries]

Returns:

function

retryable

public static <V> Supplier<V> retryable(Supplier<V> base,
 Class<? extends Throwable> exceptionClass,
 int maxRetries,
 int maxDelayBetweenRetries)

Returns a Supplier that retries execution on failure.

Type Parameters:

V - type of supplied result

Parameters:

base - base supplier

exceptionClass - type of exception for which to retry

maxRetries - max number of retries before giving up

maxDelayBetweenRetries - max delay between successive retries. The actual delay is randomly picked from the interval (0, maxDelayBetweenRetries]

Returns:

supplier

randomDelay

public static void randomDelay(int ms)

Suspends the current thread for a random number of millis between 0 and the indicated limit.

Parameters:

ms - max number of millis

delay

public static void delay(int ms,
 int nanos)

Suspends the current thread for a specified number of millis and nanos.

Parameters:

ms - number of millis

nanos - number of nanos
