To encapsulate the policy pattern in one sentence is to "encapsulate each algorithm into a different policy class so that they can be interchanged". The following is the structure diagram of the policy mode:BIM technology can add time dimension to three-dimensional space model to carry out 4D simulation construction, which is conducive to the optimization of construction period. Based on BIM technology, 4D simulation construction can put forward a virtual construction scheme, which can pre-process various possible induced situations in the construction. The application of BIM technology in the construction stage can reduce possible errors in the process of information transmission and reduce rework.汽车世界中，一年一度的活塞杯再次拉开序幕。红色跑车“闪电”麦坤和“冠军”、“路霸”是冠军最有力的竞争者。作为新人，麦坤具有极高的天赋，同时也是一个目空一切的家伙。经过紧张激烈的对抗，这三辆车同时冲过终点线。由于无法判定最终优胜者，组委会决定一个月后在加州洛杉矶召开一次只有这三辆车参加的殊死战，只有最后的胜者才能捧得活塞杯。The Upload.prototype.init method does some initialization work, including creating some nodes in the page.
