QuickServer is an open source Java library/framework for quick creation of robust multi-client TCP server applications QuickServer provides an abstraction over the ServerSocket, Socket and other network and input output classes and it eases the creation of powerful network servers.
Example programs demonstrating the use of the library can be found with the QuickServer distribution [examples folder].
In any programming language, socket programming is not small fleet to most programmer and creating a multi-threaded multi-client network server is a nightmare for most programmers.
We always waste time in writing the same code each time we build a new software which acts has network server (handles multiple socket connections). I always create such application, so this time I have made a library - QuickServer, to handle a creation of a multi-threaded, multi-client server applications for Java.
With this library one can just concentrate on just the application logic/protocol on hand.
QuickServer divides the application logic of its developer over eight main classes:
- ClientWriteHandler [Optional Class]
Handles client write operation - Non-Blocking Mode.
- ClientAuthenticationHandler [Optional Class]
Used to Authenticate a client.
