The EMF (Eclipse Modeling Framework) Modeling framework can help us transform models (UML, XSD, etc.) into robust and rich Java code. Using EMF to build an application, not only can greatly improve the development efficiency, but also take advantage of the many features provided by EMF to ensure the robustness and perfection of the model, including model change n

Friends who have been in touch with Eclipse for some time should have heard the name EMF, an acronym for the Eclipse Modeling Framework, an important subproject of eclipse, if translated into Chinese, is the Eclipse Modeling framework. It's really hard to determine what it's for, and I think that the EMF should have a certain understanding of model-driven development (MDA), and

EMF is a modeling framework launched by the Eclipse organization. It can help us transform models (UML, XSD, etc.) into robust and rich Java code. By using EMF, the program we write can get a robust model layer for free, which is usually more robust than our own hand-written model layer. In fact, there are many commercial products that use EMF as their model laye

Descriptive descriptions can be written at the same time when the EMF file is created using the createenhmetafile function; You can use the getenhmetafiledescription function to read the description text of the EMF file. The explanatory text in this example is very simple, but the format of the standard explanatory text should be:ProgramName #0 file title #0 #0 Unit unit1; interfaceuses windows

In node, many objects will launch events. For example, a TCP server emits a "connect" event whenever a client requests a connection, or, for example, whenever a whole piece of data is read, the file system emits a "data" event. These objects are referred to as event emitters in node emitter. The event emitter allows programmers to subscribe to events of interest to them and bind the callback function to rel

In this example: Code File: Unit unit1; interfaceuses windows, messages, extensions, variants, classes, graphics, controls, forms, dialogs, stdctrls; Type tform1 = Class (tform) button1: tbutton; Procedure formcreate (Sender: tobject); Procedure formdestroy (Sender: tobject); Procedure formmousedown (Sender: tobject; button: tmousebutton; shift: tshiftstate; X, Y: integer); Procedure formmousemove; shift: tshiftstate; X, Y: integer); Procedure formmouseup (Sender: tobject; bu

The event emitter is another important asynchronous programming technique in node that is outside of the callback function. In the graphics interface programming library such as MFC, event emitter is very common, for example, mouse click event, click the mouse, will trigger the mouse click Function-Event emitter trigger event, and after the event is triggered to

This module is used to provide custom events and convert the objects implementing this interface into an event transmitter. // ================================================ ================/// Event transmitter module ================================ ============================ (function (global, doc) {var dom = global [Doc. URL. replace (/(#. + | \ W)/g, '')]; Dom. define ("emitter", "data", function () {var firetype = "", blank = "" Var ensure

Node. js emitter. emit method instructions, node. js Use Cases Method description: When an event is triggered, several optional parameters are passed to the parameter table of the event listener. Syntax: Copy codeThe Code is as follows:Emitter. emit (event, [arg1], [arg2], [...]) Receiving parameters: Event Type Arg1 ~ Parameters passed by argN (multiple) Example: Copy codeThe Code is as follows:Var events = require ('events ');Var

With the help of the best V8 in the second browser war, node. JS has achieved considerable operational efficiency in just two years and is quickly accepted. This is evident from the popularity of the node. JS Project on GitHub and the number of libraries on NPM. Node. js Event:In node. js
