震动之下，忙尾随而去，看见他进了白凡在京城的府邸。But! ! ! ! Neogeo's simulation is the most troublesome. I checked a lot of data and tested several different methods. The following is the simulation method explored by myself. It is not the only method, but for reference only.大卫·巴尔塔是一个艺术家，单身的他和母亲同住，每日为了艺术奔波。此时，他和他的父亲正在进行一项重塑名画的项目。一天和父亲偶遇了商场橱窗里一个正在设计陈列的女孩，她的设计风格令大卫眼前一亮，而同是艺术家的父亲则对女孩的样貌赞美有加，在父亲的推波助澜下，大卫向女孩迈出了更近的一步......当记得其中有‘曲则全，枉则直，洼则盈。　　在肤浅的爱情泛滥的年代，在人们相信金钱可以买到爱情的世上，在如今为了眼前利益放弃大义也算美德的污浊风气之下，金处善的一生，他的自我牺牲式的爱与忠诚更彰显出他的人格魅力。Visitor pattern decouples the data structure from the operations acting on the structure, making the operation set relatively free to evolve. Visitor pattern is suitable for systems with relatively stable data structure and easy change of algorithm. Because visitor mode makes it easy to increase algorithm operation. If system data structure objects are easy to change and new data objects are often added, visitor mode is not suitable. The advantage of visitor mode is that it is easy to add operations, because adding operations means adding new visitors. Visitor mode centralizes the relevant behaviors into one visitor object, and its changes do not affect the system data structure. Its disadvantage is that it is difficult to add new data structures. -From Encyclopedia
