Type Parameters:

R - result type

All Superinterfaces:

ExecutionContext<R>

All Known Subinterfaces:

SyncExecutionInternal<R>

public interface Execution<R>
extends ExecutionContext<R>

Tracks synchronous executions and handles failures according to one or more policies. Execution results must be explicitly recorded via one of the record methods.

Method Summary

Modifier and Type	Method and Description
void	complete() Records and completes the execution successfully.
Duration	getDelay() Returns the time to delay before the next execution attempt.
boolean	isComplete() Returns whether the execution is complete or if it can be retried.
static <R> Execution<R>	of(Policy<R> outerPolicy, Policy<R>... policies) Creates a new Execution that will use the outerPolicy and innerPolicies to handle failures.
void	record(R result, Throwable exception) Records an execution result or exception which triggers failure handling, if needed, by the configured policies.
void	recordException(Throwable exception) Records an exception which triggers failure handling, if needed, by the configured policies.
void	recordResult(R result) Records an execution result which triggers failure handling, if needed, by the configured policies.

Method Detail

of

@SafeVarargs
static <R> Execution<R> of(Policy<R> outerPolicy,
                                        Policy<R>... policies)

Creates a new Execution that will use the outerPolicy and innerPolicies to handle failures. Policies are applied in reverse order, with the last policy being applied first.

Throws:

NullPointerException - if outerPolicy is null

complete

void complete()

Records and completes the execution successfully.

Throws:

IllegalStateException - if the execution is already complete

isComplete

boolean isComplete()

Returns whether the execution is complete or if it can be retried. An execution is considered complete only when all configured policies consider the execution complete.

getDelay

Duration getDelay()

Returns the time to delay before the next execution attempt. Returns 0 if an execution has not yet occurred.

record

void record(R result,
            Throwable exception)

Records an execution result or exception which triggers failure handling, if needed, by the configured policies. If policy handling is not possible or completed, the execution is completed.

Throws:

IllegalStateException - if the execution is already complete

recordResult

void recordResult(R result)

Records an execution result which triggers failure handling, if needed, by the configured policies. If policy handling is not possible or completed, the execution is completed.

Throws:

IllegalStateException - if the execution is already complete

recordException

void recordException(Throwable exception)

Records an exception which triggers failure handling, if needed, by the configured policies. If policy handling is not possible or completed, the execution is completed.

Throws:

IllegalStateException - if the execution is already complete
