how to waiter for dummies

In traditional socket IO, you need to create a thread for each connection, and when the number of concurrent connections is huge, the overhead of the stack memory and CPU thread switching that the thread consumes will be huge. With NIO, you no longer need to create a separate thread for each thread, you can use a thread pool with a limited number of threads, or even a thread for any number of connection services. Because the number of threads is less than the number of connections, each thread d

On summer nights, the street is always lively and extraordinary. People like to eat barbecue and drink beer with friends of about three or five. It's just like eating kebab and singing songs. Walking down the street, I suddenly found that there were not many people in a barbecue stall, so you came up and said to your boss, "Come on, 10 strings of mutton, 3 strings of chicken wings ....... After that, you will wait, and you will find that there are more and more people talking to your boss a

Singleton mode refers to a class, with only one instance. The idea of implementation is to add judgment when creating an instance, and if there are instances then return if there is no new one and return. First step: Create a class.function Waiter (ID, name, salary) { //created a waiter class Employees.call ( This, ID, name, salary)//Here waiter inherited the Emp

respondent model better understand some. By understanding that this pattern is more like a bodyguard, has been waiting for your call, or call the Beast.Concurrent systems often use reactor mode, instead of common multithreading, saving system resources and improving the throughput of the system.A more intuitive way to introduce the advantages of this way, by comparing with the usual multi-threaded way, may be better understood.Take a food and beverage as an example, each person to eat is an eve

Multiple Inheritance (MI) Describes a class that has multiple direct base classes. As with single inheritance, the total MI representation is also a is-a relationship. For example, you can derive the Singingwaiter class from the Awiter class and the singer class:Class Singingwaiter:public Waiter, public Singer {...};MI may bring many new problems to the programmer. The two main problems are: Inherit the same name method from two different base classes

The first * represents the return type, the second one represents the method name, and the. A method that represents an arbitrary entry parameter;Execution (* *to (..)) LMatches all
