Proxy is an object, which can be used to control access to ontology objects. It implements the same interface as ontology objects. Proxy objects will pass all calling methods to ontology objects. The most basic form of the proxy mode is to control access, while the ontology object is responsible for executing the function or class of the assigned object. Simply speaking, the local object focuses on executing the code on the page, while the proxy controls when the local object is instantiated and used. We have used some proxy patterns in the above monomer patterns, that is, using proxy patterns to instantiate the monomer patterns, and leaving other things to ontology objects.After entering the school, the flying cadets will have to undergo a third examination immediately, which is more detailed than the second. Those who fail will be transferred to the ground handling major and will not have the chance to fly into the blue sky. In the future study process, some students with relatively low grades will be brushed off every semester. The last rest accounts for about 30%-40% of the enrolment. These people will become real pilots.9.1 Serious digestive system diseases, dysfunction or surgical sequelae are unqualified.五月底的一个晚上，玉米将攒的金银和几串珍珠从枕头底下翻出来，先将金子和两串珍珠包成两个小包，放进裤裆里，再把裤子从大腿根处扎紧，又在外面套了一条裤子。文帝村是以汉文帝陵命名的村庄，和大都市紧紧相连。在城市基础建设不断扩充的过程中，文帝村的土地像切豆腐一样被切走。村党支部书记杨明亮在村里工作了三十多年，看到土地流失非常痛心，但又无力阻止。村里划地得到一百万，老书记想留着给村办企业做资金，村长和村委会成员以少数服从多数的决定，把钱在村里分掉。他从怀里掏出一个小布包，挑出一张膏药，努力用小指甲剥开，滋啦一声撕下来，小心翼翼地托着蛋蛋，把这治跌打损伤的膏药从下面一兜，再往上一裹，把两颗蛋蛋包的严严实实，还用手抹了两下，让膏药贴得更服帖，然后才舒了口气。In TCP implementation, when receiving the SYN request from the client, the server needs to reply the SYN + ACK packet to the client, and the client also needs to send the confirmation packet to the server. Usually, the initial serial number of the server is calculated by the server according to certain rules or adopts random numbers. However, in SYN cookies, the initial serial number of the server is obtained by hash operation and encryption of the client IP address, client port, server IP address, server port and other security values, which is called cookie. When the server suffers from SYN attack and makes the backlog queue full, the server does not reject the new SYN request, but replies the cookie (SYN serial number of the reply packet) to the client. If it receives the ACK packet from the client, the server subtracts 1 from the ACK serial number of the client to obtain the cookie comparison value, and performs a hash operation on the above elements to see if it is equal to the cookie. If equal, complete the three-way handshake directly (Note: At this time, you don't need to check whether this connection belongs to the backlog queue).
