xSocket 1.2

xSocket provides a Java nio-based server framework.
xSocket is based on the Java NIO package. It handles low level I/O operations, and implements a thread, buffer and connection management in a very efficiency way. The underlying threading and synchronization management ensures high performance and high scalability by using multithreading.
Main features:
- client side blocking and non-blocking connections
- server side non-blocking connections
- a dynamic callback handler architecture to provide asynchronous communication approaches
- SSL (which can also be activated in a ad-hoc manner),
- QualityOfService management by providing a dynamic data transfer rate control,
- TCP and UDP transport protocol
Enhancements:
New features:
- [*] read/writeShort method has been added for IDataSink/IDataSource
- [*] getOption() method has been added for IEndpoint and IConnection ( SocketConfiguration has been deprecated)
- [stream] IConnection: suspendRead & resumeRead methods has been added
- [stream] IServerContext: getWorkerpool method has been added
- [stream] all read by delimiter methods now supports a (overloaded) signature with encoding
- [stream] getPendingWriteDataSize() method has been added for the IConnection interface
- [stream] an SPI interface has been defined to plugin external nio providers
- [stream] handler support for NonblockingConnectionPool has been added
Bug fix/Implementation changes:
- [*] IWorkerPool has been deprecated/replaced by java.util.concurrent.Executor
- [*] DynamicWorkerPool has been deprecated. Use java.util.concurrent.Executor implementation instead
- [stream] MultithreadedServer: by default host address "0.0.0.0" will be used instead of getLocalHost()
- [stream] the MultithreadedServerMBeanProxyFactory and ConnectionPoolMBeanProxyFactory class have been moved to the stream package
- [stream] some low level related settter and getter methods of the IMultithreadedServer has been deprecated
- [stream] internal performance/thread optimizations (especially for non multithreaded server mode (workerpool == null))
- [stream] BUG onDataHandler call loops by using the read mark-methods has been fixed
- [stream] BUG throwing of an io exception by handling method (onData, onConnect, ...) doesnt close the connection
- [stream] BUG read by delimiter in a readMarked mode swallows the delimiter has been fixed as suggested by Karsten Ohme. Thanks!
- [stream] BUG closing of a closed Connection throws an io exception has been fixed. If the connection is already closed then invoking of this method will have no effect
- [stream] the low level io classes of xSocket has been moved to a dedicated io package (which implements the SPI)
- [stream] ThrottlingWriteHandler (which supports the setWriteTransferRate method) has been rewritten
- [stream] IoSocketHandler: performance optimization: close will only initiate a write loop if there really remaining data to write
