Package dev.failsafe

APIs for performing failsafe executions.

See: Description

Interface Summary

Interface	Description
AsyncExecution<R>	Allows asynchronous executions to record their results or complete an execution.
Bulkhead<R>	A bulkhead allows you to restrict concurrent executions as a way of preventing system overload.
Call<R>	A call that can perform Failsafe executions and can be cancelled.
CircuitBreaker<R>	A circuit breaker temporarily blocks execution when a configured number of failures are exceeded.
Execution<R>	Tracks synchronous executions and handles failures according to one or more policies.
ExecutionContext<R>	Contextual execution information.
Fallback<R>	A Policy that handles failures using a fallback function or result.
Policy<R>	A policy for handling executions.
PolicyListeners<S,R>	Configures listeners for a policy execution result.
RateLimiter<R>	A rate limiter allows you to control the rate of executions as a way of preventing system overload.
RetryPolicy<R>	A policy that defines when retries should be performed.
Timeout<R>	A policy that cancels and fails an excecution with a TimeoutExceededException if a timeout is exceeded.

Class Summary

Class	Description
BulkheadBuilder<R>	Builds Bulkhead instances.
BulkheadConfig<R>	Configuration for a Bulkhead.
CircuitBreakerBuilder<R>	Builds CircuitBreaker instances.
CircuitBreakerConfig<R>	Configuration for a CircuitBreaker.
DelayablePolicyBuilder<S,C extends DelayablePolicyConfig<R>,R>	A builder of policies that can be delayed between executions.
DelayablePolicyConfig<R>	Configuration for policies that can delay between executions.
Failsafe	Simple, sophisticated failure handling.
FailsafeExecutor<R>	An executor that handles failures according to configured policies.
FailurePolicyBuilder<S,C extends FailurePolicyConfig<R>,R>	A Policy that allows configurable conditions to determine whether an execution is a failure.
FailurePolicyConfig<R>	Configuration for policies that handle specific failures and conditions.
FallbackBuilder<R>	Builds Fallback instances.
FallbackConfig<R>	Configuration for a Fallback.
PolicyBuilder<S,C extends PolicyConfig<R>,R>	Builds policies.
PolicyConfig<R>	Configuration for a Policy.
RateLimiterBuilder<R>	Builds RateLimiter instances.
RateLimiterConfig<R>	Configuration for a RateLimiter.
RetryPolicyBuilder<R>	Builds RetryPolicy instances.
RetryPolicyConfig<R>	Configuration for a RetryPolicy.
TimeoutBuilder<R>	Builds Timeout instances.
TimeoutConfig<R>	Configuration for a Timeout.

Enum Summary

Enum	Description
CircuitBreaker.State	The state of the circuit.

Exception Summary

Exception	Description
BulkheadFullException	Thrown when an execution is attempted against a Bulkhead that is full.
CircuitBreakerOpenException	Thrown when an execution is attempted against a CircuitBreaker that is open.
FailsafeException	Thrown when a synchronous Failsafe execution fails with an Exception, wrapping the underlying exception.
RateLimitExceededException	Thrown when an execution exceeds or would exceed a RateLimiter.
TimeoutExceededException	Thrown when an execution exceeds a configured Timeout.
