Package org.kiwiproject.retry

Class KiwiRetryerPredicates

java.lang.Object

org.kiwiproject.retry.KiwiRetryerPredicates

public class KiwiRetryerPredicates
extends Object

Some potentially useful predicates that can be used out of the box with KiwiRetryer or directly with RetryerBuilder, or anything else that accepts a Guava Predicate.

Note that the Jakarta RS-API needs to be available at runtime to use the Response predicates.

Implementation Note:

These use Guava's and not the JDK's predicate class, because the guava-retrying library used in KiwiRetryer uses Guava's Predicate.

Field Detail

UNKNOWN_HOST

public static final com.google.common.base.Predicate<Throwable> UNKNOWN_HOST
