Example 1 with MaxRetriesReachedException

use of org.hyperledger.besu.ethereum.eth.manager.exceptions.MaxRetriesReachedException in project besu by hyperledger.

the class AbstractRetryingPeerTask method executeTask.

@Override
protected void executeTask() {
    if (result.isDone()) {
        // Return if task is done
        return;
    }
    if (retryCount > maxRetries) {
        result.completeExceptionally(new MaxRetriesReachedException());
        return;
    }
    retryCount += 1;
    executePeerTask(assignedPeer).whenComplete((peerResult, error) -> {
        if (error != null) {
            handleTaskError(error);
        } else {
            // If we get a partial success, reset the retry counter.
            if (!isEmptyResponse.test(peerResult)) {
                retryCount = 0;
            }
            executeTaskTimed();
        }
    });
