Static proxyFirst implementation (interface-based):1 "InterfacePublic interface Hello { void Say (String msg);}2 "target class, implement at least one interfacepublic class Helloimpl implements Hello { public void Say (String msg) {

Each winform class derived from the control class (including the control class) is executed based on the underlying Windows message and a message pump loop. Message loops must have a corresponding thread, because messages sent to a window are

The delegate is used in the use of invoke or begininvoke without exception. I. Why does the control class provide the invoke and begininvoke mechanisms? The main reason for this problem is already well known by dotnetprogrammers. I have recorded my

Proxy ?? Proxy refers to a person who works on behalf of others. The proxy actually uses the delegate mechanism. During the proxy process, you can do something else and then execute the code of the proxy object. Knowledge reserve 1. When to

First, the basic concept of the agent1, the Life of the agent: for example, buy a computer we often buy from agents, rather than directly to the headquarters directly to buy, no matter where to buy the computer is the same, from the agent there to

One, reflection in Java 1. Load class properties and method instance code by reflection: /** * Java.lang.Class is the source of reflection * We created a class that generates the corresponding class file by compiling (Javac.exe), after which

54dabangIn the spring learning process, we can see the benefits of dynamically managing bean objects through configuration files ( loose coupling allows the scattered parts to form a whole, and the whole does not care about the details of each other,

In many cases, we need a singleton form, for example, Task Manager can be a singleton in the Windows application system, so we do this: add a static point member to a single piece in the implementation of the Form class. Provides a static

AOP: Facets oriented, aspect oriented, interface oriented is a crosscutting techniqueApplication of crosscutting Technology:1. Transaction management: (1) Database transactions: (2) Programming transactions (3) declaring things: Spring aop-->

OverviewThe Spring JDBC Abstract Framework Core package provides the JDBC template class, where JdbcTemplate is the core class of a core package, so other template classes are based on its encapsulation, and the JDBC template class is the first mode

In addition to directly invoking the open source organization to provide the jar package, what I want to say today is the final version of JDBC, we need to play more practice more understanding. The most important thing is to understand. Don't say

When we learn spring, we know that spring has two main ideas, one is the IOC, the other is AOP, and for IOC, dependency injection doesn't have to be said, and for spring's core AOP, we not only need to know how to satisfy our function through AOP,

The concept of an agent: a simple understanding is that by creating a proxy object for an object, we do not directly reference the original object, but rather the proxy object created to control the reference to the original object.Dynamic Proxy:

When we learn spring, we know that spring has two main ideas, one is the IOC, the other is AOP, and for IOC, dependency injection doesn't have to be said, and for spring's core AOP, we not only need to know how to satisfy our function through AOP,

Dynamic Proxy for JavaAgent modeProxy mode is a common Java design pattern, his characteristic is that the proxy class has the same interface with the delegate class, the proxy class is mainly responsible for preprocessing the message for the

In the dynamic agent mechanism of Java, there are two important classes or interfaces, one is Invocationhandler (Interface), the other is proxy (class), and this class and interface is necessary to implement our dynamic proxy. First, let's take a

Observer pattern vs. Java delegate The so-called Observer pattern , refers to the need to trigger a series of related actions at the same time, it exists the observer and the notifier two concepts, the notifier holds the observer's abstract
