randomize()会自己调用pre_randomize()和post_randomize()这两个函数。 如果没有定义pre_randomize()和post_randomize()这两个函数,那么就可以认为这两个函数是什么也不做的。 可以根据自身需要重写pre_randomize()和post_randomize()这两个函数。 这儿可能会想到,对这些在pre_randomize()中设置的变量,也可以在别...
post_randomize()的内建定义如下: function void post_randomize; if (super) super.post_randomize(); // 检测super以便确定对象句柄是否存在 //可选的在随机化之后的编程从这里开始 endfunction 当调用obj.randomize()的时候,它首先调用obj的pre_randomize()方法以及它的所有被使能的随机对象成员。接下来pre_rand...
类中声明为rand或randc的变量使用内置的randomize()方法随机化。如果随机化成功,该方法返回1,如果失败,则返回0。由于各种原因,如约束冲突、解算器无法得出满足所有约束的值等,它可能会失败。类对象不会自动随机化,因此我们应该始终调用randomize()方法进行随机化。 文章目录 randomize 语法 pre_randomize() post_random...

Background: Data on preemptive analgesia in periodontal surgeries are scarce and still diverse. The aim of this study was to evaluate and compare the analgesic effects of the preemptive administration of ibuprofen and nimesulide in open flap periodontal surgeries.
