Constructor Detail

AsyncExecutionImpl

AsyncExecutionImpl(java.util.List<Policy<R>> policies,
                   Scheduler scheduler,
                   FailsafeFuture<R> future,

                   java.util.function.Function<AsyncExecutionInternal<R>,java.util.concurrent.CompletableFuture<ExecutionResult<R>>> innerFn)

AsyncExecutionImpl

private AsyncExecutionImpl(AsyncExecutionImpl<R> execution)

Create an async execution for a new attempt.

Method Detail

complete

public void complete()

Description copied from interface: AsyncExecution

Completes the execution and the associated CompletableFuture.

Specified by:

complete in interface AsyncExecution<R>

isComplete

public boolean isComplete()

Description copied from interface: AsyncExecution

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.

Specified by:

isComplete in interface AsyncExecution<R>

record

public void record(R result,
                   java.lang.Throwable exception)

Description copied from interface: AsyncExecution

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

Specified by:

record in interface AsyncExecution<R>

recordResult

public void recordResult(R result)

Description copied from interface: AsyncExecution

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

Specified by:

recordResult in interface AsyncExecution<R>

recordException

public void recordException(java.lang.Throwable exception)

Description copied from interface: AsyncExecution

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

Specified by:

recordException in interface AsyncExecution<R>

isAsyncExecution

public boolean isAsyncExecution()

Description copied from interface: AsyncExecutionInternal

Returns whether the execution is an async integration execution.

Specified by:

isAsyncExecution in interface AsyncExecutionInternal<R>

isRecorded

public boolean isRecorded()

Description copied from interface: AsyncExecutionInternal

Returns whether one of the public AsyncExecution record or complete methods have been called.

Specified by:

isRecorded in interface AsyncExecutionInternal<R>

setPostExecuted

public void setPostExecuted(int policyIndex)

Description copied from interface: AsyncExecutionInternal

Sets the PolicyExecutor corresponding to the policyIndex as having post-executed.

Specified by:

setPostExecuted in interface AsyncExecutionInternal<R>

isPostExecuted

public boolean isPostExecuted(int policyIndex)

Description copied from interface: AsyncExecutionInternal

Returns whether the PolicyExecutor corresponding to the policyIndex has already post-executed.

Specified by:

isPostExecuted in interface AsyncExecutionInternal<R>

copy

public AsyncExecutionInternal<R> copy()

Description copied from interface: AsyncExecutionInternal

Returns a new copy of the AsyncExecutionInternal.

Specified by:

copy in interface AsyncExecutionInternal<R>

executeAsync

void executeAsync()

Performs an asynchronous execution.

complete

private void complete(ExecutionResult<R> result,
                      java.lang.Throwable error)
