Interface AsyncFilter

public interface AsyncFilter

An interface marker used to execute operations before a AsyncProcesssorTask in pre/post or interrupted. Usually, implementation of this interface is called by an instance of AsyncExecutor. Using an AsyncExecutor, it is possible to suspend or resume the current request processing. Once suspended, the request can always be resumed using the AsyncExecutor, and the normal Grizzly invocation path will be used (like calling Adapter#service or GrizzlyAdapter#service). To invoke the GrizzlyAdapter from an AsyncFilter, just invoke AsyncExecutor.execute(), and then calling AsyncExecutor.postExecute() will commit the response. Implementation of this interface must be thread-safe.
