the JDK's dynamic proxy to generate the proxy object, and if the class does not implement any interfaces, use Cglib to generate the proxy object.Terminology of AOPJoinpoint (connection point): The so-called connection point refers to the points that are intercepted. In spring, these points refer to methods because spring only supports connection points of method types .Pointcut (pointcut): The so-called pointcut is the definition of which joinpoint we want to intercept.Advice (Notification/enha
connection points for method types that contain fields and constructors. Why is it? Because the field it is through the Get,set method, the constructor is actually also a method. Spring only supports connection points for method types and connection points are fields or constructors they are containment relationships.4. Entry pointThe connection point to intercept the definition, the connection point can be many, but not necessarily each connection point to operate, such as Lotus Root, Lotus ro
Spring's surround notification and predecessor notifications, there are two major differences between post notifications: 1. The call to the target method is determined by the surround notification, that is, you can decide whether to call the target method, and the forward and post notifications are not determined, they just execute the notification before and after the call to the method, That is, the targ
can be implemented (based on the @AspectJ) with regular classes (based on Shcema) or with regular classes and annotations . b) Notification (Advice): An action performed by a slice at a particular connection point is called a notification. Different types of notifications include pre-notification, surround notification, post-notification, and more. Many AOP frameworks, including Spring, simulate notifications as an interceptor and maintain an interce
Enhanced Type
Enhancements (advice) are mainly comprised of the following five types1. Predecessor Enhancement (beforeadvice): Enforcing enhancements before the target method executes2. Post-Enhancement (Afterreturningadvice): Implement enhancements after the target method is implemented3. Surround Enhancement (Mrthodinterceptor): Implement enhancements before and after the target method is performed4. Exception throwing Enhancement (Throwsadvice): E
current path should be populated when the fill () method is called. Canvas use "Non 0 Wrapping rules" (nonzero winding rule) to determine when filling the path that crosses each other. Figure 2-14 illustrates the application of this rule.
The "Non 0 surround rule" is the way to judge a path with a self crossover: for any given region in the path, draw a long enough segment from within the area to make the end of the segment fall completely outside t
The Dojo/aspect module is an implementation of AOP in the Dojo framework. For a detailed explanation of AOP please read the other information separately, here is a brief review of the basic concepts of AOP:
Facets (Aspect): In fact, the realization of common functions. such as log plane, permission plane, transaction plane, and so on.
Notification (Advice): is the specific implementation of facets. The target method is the reference point, depending on where it is placed, it can be

Features: After the image is stretched or reduced, it looks distorted, but the effect is better than gl_nearest. It does not seem to have any trace after manual operation.

Features: When the texture is stretched to a very large scale, a large volume of mottled pixels will appear.
The two member variables after texparameters are called the texture surround

zombie and skeleton in a team. When MF was used, I wanted to put the skeleton in front, you can first press tab (because the priority of the skeleton is lower than that of the zombie) to select the skeleton and press Ctrl to move it to the front. You will find that only the skeleton is moving and the zombie is not moving.

One m key: the intention is to move, but we can extend it to surrounded. Yes, it is the legendary
