uml diagram from java code

EMF is a major part of the Eclipse platform and is the basis for a number of relevant technologies and frameworks, such as Eclipse Visual Editor, SDO, XSD, and uml-, many of which are integrated into Rational®application develope R and Websphere®business Modeler and other IBM® platforms. The EMF now absorbs a number of Java technical features, such as enumeration types, annotations, and generics. In most d

client is successful after the payment of the micro-trust through the URL to our own server to submit some data, and then we analyze the data in the background, to complete our own operation. This way we know if the customer has actually paid through the micro-letter. So the whole process ends, and this is mode two. Micro credit A timeline diagram that represents this process. The expression is more complex, looks more laborious, summed up in fact

. Repeat this process until a valid node is deleted. Returns null if the queue has not been deleted successfully after traversing. The following figure is a successful deletion of the structure diagram: from the above figure, we can see that, during the delete operation, the head over the number of nodes reached the threshold, triggering the executive head of the update, so that it points to the C node. After removing the header node from above, th

author's experience of a part of a project, through this example to analyze the process of code optimization. The following is a brief introduction to the relevant parts of the system. The system's development language is Java, deployed in a total of 4 of the CPU's Linux server, the relevant part of the main operations: through an external system D provided by the REST API to obtain information, extract e

NiO is used in jdk1.4, which can be said to be "new I/O", or non-blocking I/O. Here's how Java NIO works: All IO events are handled by a dedicated thread and are responsible for distribution. Event-driven: events are triggered when they arrive, rather than synchronized to monitor events. Thread communication: The threads communicate through wait,notify and other means. Ensure that each context switch is meaningful. Reduce unnecessary

Preface: recently in the analysis of the RPC (remote Procedure call Protocol) of Hadoop, it is a protocol that requests services over a network from a remote computer program without needing to know the underlying network technology. can refer to: http://baike.baidu.com/view/32726.htm) mechanism, found that the implementation of the RPC mechanism of Hadoop is mainly used in two technologies: Dynamic agent (dynamic Agent can refer to the blog:/http) weixiaolu.iteye.com/blog/1477774) and

corresponding Bean object (such as the ConfigurationClassPostProcessor instance) through the Spring framework ). According to the Spring context source code, this object is a tool class of the processor type. The Spring container will call the postProcessBeanDefinitionRegistry (…) of the processor before instantiating the Bean defined by the developer (...) Method. In this example, Bean Definition is configured based on

, the following first describes the following types.Strong referencesThis is the most commonly used reference type, and when you execute the following statement, the variable is o a strong reference.Object o = new Object (); The object that the strong reference points to is not cleaned by the GC at any time. In general, for resident-class applications (such as server), the memory consumed tends to rise over time, and if the program uses strong references, it is easy to cause a memo

The simple analysis is as follows:First look at the following code: import java.io.UnsupportedEncodingException; Public class charsettest { Public Static void Main (string[] args) throws unsupportedencodingexception { String test = "basketball"; byte

Topic:The gray code is a binary numeral system where the successive values are differ in only one bit.Given a non-negative integer n representing the total number of bits in the code, print the sequence of gray code . A Gray code sequence must begin with 0.For example, given n = 2, return [0,1,3,2] . Its gray

The adorner pattern can dynamically add capabilities to existing objects. Next, I'll use a simple example to illustrate how to use the decorator pattern in a program. 1. Decorator Mode Let's assume that you're looking for a girlfriend. There are a lot of girls from different countries, such as: The United States, China, Japan, France and so on, each of them have a unique personality and hobbies, if you need to simulate such a situation in the program, assuming that every girl is a
