Between program writing, the Flying Knife still allows everyone to see how the pursuit uses IP addresses to determine the source of the user (Grace, now we need to reveal the "old bottom" of "hunting, hello, everyone ).If you want to write a tracing software, the first thing you think of is to collect an IP allocation table and store them in the database for reading. An IP allocation table exists in the

picky, and that it takes some time Dog is also a subclass of inherited animal, and it implements the Doorgod interface to guard the house. First of all, the trace-back modelling (upcasting). This term is derived from the traditional representation of inheritance graphs: to the top of the base class, and to the downward development of the derivation class. According to the above sample, I give one of the following small applications: public class Main {public static void Upcasting (Animal A

Since we lost specific types of information during tracing (moving up in the inheritance structure), we had to use the "trace-back" technique in order to get concrete type information-that is, moving down the hierarchy. However, we know that a tracing model is certainly safe; the underlying class cannot have a larger interface than a derived class. Therefore, every message we send through the underlying cla

previous macro definition is set to 0. When you need to modify the masking of multiple printf_debug functions, simply focus on the code block of the previously defined macro. This reduces the range of operations from 3000 lines to 6 rows.When we need to focus on all the debug functions, we might as well define one more macro1 #define Debug_qemu_io_modeWe can use this macro to control the existence of all printf_debug functions at once, such as12 printf_debug (path_paio_submit, "Raw-posix.c-ra
