java实现区间树钟

This project moved to http://github.com/sinabz/itc4j This is a small library which implements Interval Tree Clocks (ITC), a logical clock for tracking causality in dynamic distributed systems. You can find details about the concept at http://gsd.di.uminho.pt/teaching/misd/2010/sm/itc.pdf. The following comes directly from the paper mentioned above: "This paper addresses causality tracking in dynamic settings and introduces Interval Tree Clocks (ITC), a novel causality tracking mechanism that generalizes both Version Vectors and Vector Clocks. It does not require global ids but is able to create, retire and reuse them autonomously, with no need for global coordination; any entity can fork a new one and the number of participants can be reduced by joining arbitrary pairs of entities; stamps tend to grow or shrink adapting to the dynamic nature of the system. Contrary to some previous approaches, ITC is suitable for practical
