Zynaptic reaction is a flexible Java asynchronous programming framework for implementing complex event-driven applications. It is largely influenced by the twisted programming framework of the Python programming language developed by http://www.aliyun.com/zixun/aggregation/17078.html ">twistedmatrix Labs".
The main features of reaction library are concurrency and callback model, and as a neutral application. It can be used to manage a large amount of concurrent I/O or transfer compute-intensive tasks to multi-core processors, which can serve as a basic Java library, and reaction can also be run as a stand-alone OSGi service and incorporated into any GUI framework you choose.
Zynaptic reaction beta3 This version has a major update to the reaction framework, including the introduction of Java generics to improve the reliability and maintainability of application code. This version of the standard license has also been changed to the GPLV2 license Classpath exception.
