Interface AsyncDocumentRequestHandler

All Superinterfaces:

DocumentRequestHandler

All Known Implementing Classes:

DefaultDocumentRequestHandler

public interface AsyncDocumentRequestHandler
extends DocumentRequestHandler

Provides an interface for Asynchronous request handling. The resourceRequestedAsync will be called without creating a new thread, but it has to return immediately. This can be useful when an external threading mechanism is to be utilized instead of the internal threading which is done by HTMLComponent. Note that the resourceRequested method should be implemented as well, since HTMLComponent has situations in which a resource needs to be fetched immediately (And block all the rest).

callback - The HTMLComponent that should be called back when the stream was fetched.
