Examples with ElementProcessor org.apache.inlong.manager.workflow.processor.ElementProcessor used on opensource projects

Example 1 with ElementProcessor

use of org.apache.inlong.manager.workflow.processor.ElementProcessor in project incubator-inlong by apache.

the class ProcessorExecutorImpl method executeStart.

@Override
public void executeStart(Element element, WorkflowContext context) {
    ElementProcessor processor = this.getProcessor(element.getClass());
    context.setCurrentElement(element);
    // If the current component needs to be skipped, proceed directly to the next one
    if (isSkipCurrentElement(element, context)) {
        executeSkipAndNext(element, context);
        return;
    }
    processor.create(element, context);
    if (processor.pendingForAction(context)) {
        return;
    }
    // If it is a continuous task execution transaction isolation
    if (element instanceof WorkflowTask) {
        transactionHelper.execute(executeCompleteInTransaction(element, context), TransactionDefinition.PROPAGATION_NESTED);
        return;
    }
    executeComplete(element, context);
}

    if (!(processor instanceof SkipableElementProcessor)) {
        throw new WorkflowException("element processor not instance of skip processor " + element.getDisplayName());
    }
    // Execute skip logic
    SkipableElementProcessor skipableProcessor = (SkipableElementProcessor) processor;
    skipableProcessor.skip(element, context);
    // Execute next
    context.getActionContext().setAction(((NextableElement) element).defaultNextAction());
    List<Element> nextElements = processor.next(element, context);
    nextElements.forEach(next -> executeStart(next, context));
}
