Integer类有实例方法times,依次传递0到n-1给后面的代码块,相当于运行n次后接的代码块。 这一代码就是在5上调用方法times Q:Ruby代码中很少看见for...in/foreach的写法,为什么? 相比for i in xx的循环方式,Ruby的风格是更喜欢用xx.each {|i| }这种调用迭代器方法的方式。 对于数组for elem in array,迭代...
It is an 8-byte integer intended to be time-sorted and unique across the fleet of servers saving messages. It is a bit-mapped integer consisting of these parts: "Application Epoch" milliseconds (number of seconds since the designated start). positive sign and 41 bits. "Worker Id", a ...
→ integer Show source 删除指定的文件,返回作为参数传递的名称数量。发生任何错误都会引发异常。另见Dir::rmdir。 代码语言:javascript 复制 static VALUE rb_file_s_unlink(int argc, VALUE *argv, VALUE klass) { return apply2files(unlink_internal, argc, argv, 0); } directory?(file_name) → true...

GC.stress调试选项现在可以设置一个integer的标志,来控制强调垃圾回收器的哪一部分。 GC.stress = true # full GC at every opportunity GC.stress = 1 # minor marking at every opportunity GC.stress = 2 # lazy sweep at every opportunity GC.stat的输出已经被更新为包括更多细节,以及方法本身现在接受一个...
