Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.

This book isn t for uber-programmers who already have all the answers. If you think that J2EE does everything that you need it to do and you can make it sing, this book is not for you. Believe me, there are already enough books out there for you.

在一個多人連線伺服器中,我們要有一個伺服端執行緒負責傾聽是否有客戶端連線,如果有客戶端連線,就指派一個客戶端執行緒專門應付這個客戶端連線,並在客戶端佇列中記錄它,然後進入下一個傾聽。 一個客戶端執行緒的工作,就是讀取客戶連線端的使用者輸入訊息,它不負責回應訊息,而是將讀到的訊息加入訊息佇列中,此外在我們的範例中,客戶端執行緒也負責自己的連線狀態,如果使用者中斷連線,客戶端執行緒會負責將自己從客戶端佇列中清除。 廣播執行緒負責取出訊息佇列中的訊息,然後將之一一傳送訊息給客戶端佇列中尚存在的客戶端執行緒。
