cache types can also bring different efficiencies. For example, when choosing the best I/O length of the system, that is, the size of the buffsize and the file system block length consistent, you can get the best time. When using standard I/O functions, each time a character function fgetc, FPUTC and each line function fgets, fputs function compared to spend more CPU time, and each time a single byte call system I/O will take more time, if it is a 100M file, It takes about 200 million function

First, it treats the constructor as a separate function and contains the class property set. These properties can be a method, a getter, a setter, a public variable, or a private variable. The node also stores a pointer reference to the parent class, which also stores the constructor, the property set,

In this series of Groovy Quest Mop Nine interceptor, we have detailed the various aspects of a simple interceptor class, allowing us to initially have the basis of interceptors. This article needs to further implement our AOP programming with interceptor classes, based on the previous interceptor class.
First of all, in the first installment of this series, the methods we intercept are fixed. Now, we need to extend it to a user of the Interceptor cla

All project names-from job names to formal names-are ambiguous, so it's a good way to make choices about what you need to do to explore the project when you name it. The name of a project can have a profound effect on its results and the behavior of its participants, and there are several ways to help us create a name that is not ambiguous: heuristic naming Method--first a name, then three reasons why
