Builder mode definition:Separates the construction of a complex object from its representation, so that the same construction process can beTo create a different representation. The builder mode is used to create a complex object step by step.Users can build complex objects only by specifying the types and content of complex objects. users do not know the specific internal construction details. The

1. Understanding of the "process" and "parts" of builder mode decoupling:Taking assembling a car as an example, an automobile can be composed of components such as the engine, steering wheel, and wheel. To assemble these components into a complete automobile, a complicated process is required. Similar components are assembled in different automobile factories and become different automobiles. This is the original requirement prototype of the

1, the use of the scene: If you need to separate the construction of a complex object from his presentation so that the same build process can create different representations of intent, we need you to apply a design pattern,' builder mode ', also known as the generator pattern. The builder model separates the internal representation of a product from the production process, allowing a const

Design Model learning-BuilderWhat Builder: separates the construction and representation of a complex object so that different representations can be created during the same building process. Why Builder is also a creation mode. It is a step-by-step Wizard to create a complex object. The Builder interface defines parts for creating complex objects, director cr

1 overviewThe Builder model (Builder pattern) is primarily used to "step through a complex object", where "step-by-step" is a stable algorithm, and parts of complex objects often change. Therefore, the builder model is mainly used to solve the demand change of "object part". This allows finer control over the process of object construction. 2 ExampleIn the produ

One of the hardest things to do when writing an application with multiple languages and tools is to create and maintain interfaces to the definition file. Luckily, C++builder has done all this for you. When adding one to a project. Pas file, C++builder automatically creates a. hpp file. In the CPP file, you can invoke Pascal's functions, objects, and so on. This provides a convenient way for the programmer

We usually do Development You can use a variety of dialog boxes. Platform Developers will know that most platforms only provide a few simple implementations. If we want to implement a dialog box that meets our specific needs, you may first think of it, rewrite our own dialog box through inheritance and other methods. Of course, this is also a good Solution Method, but in general, this is the case. We may only use the rewrite dialog box in a specific place. To use it this time, we will create

[1] basic concepts The construction (builder) mode is a design mode for object construction. It can abstract the construction process of complex objects (abstract categories ), different implementation methods of this abstract process can be used to construct objects with different performances (attributes. [2] Simple Analysis Let's take a look at the UML structure of the design pattern. It is a structure chart of the Strategy mode, which allows us t
