Examples of AsyncComponent

org.hive2hive.core.processes.framework.decorators.AsyncComponent
A {@link ProcessDecorator} that executes, and if necessary rollbacks, the wrapped {@link IProcessComponent}in an asynchronous manner.
Note:
An asynchronous component is executed in an own thread and therefore independent of all other components in a process composite.
If existing, the parent container component of an {@link AsyncComponent} is responsible to await the resultof the asynchronous component. Therefore, the usage of {@link SequentialProcess} is highly recommended.
In case of a failure within the asynchronous component, it rollbacks itself in its own thread and returns the resulting {@link RollbackReason}. In case the {@link AsyncComponent} needs to be cancelled due to afailure in another place in the whole composite, the wrapped component (if necessary) is rolled back in the detecting thread. @author Christian
