OverviewThe builder pattern is a more complex creation pattern that separates the client from the creation of complex objects that contain multiple components (or parts), and the client does not need to know the internal components and assembly methods of complex objects, only the type of builder required. It is concerned with how to create a complex object step by step, different concrete builders define d

The builder pattern is used to create relatively complex, composed objects. It includes several types of roles: Product: The object to be created, in this case the table Builder: Create an abstraction of an object method, in this case Tablebuilder ConcreteBuilder: The implementation of a specific creation, in this case Tablebuilderimpl Director: Package

MotivationAn RTF (Rich Text Format) document Interchange Format reader should be able to convert RTF to a variety of body formats. The reader can convert RTF documents into different ASCII text or into a body window component that can be edited interactively. But the problem is that the number of possible conversions is unlimited.

But for how to assemble, the purchasing manager does not know also does not care, therefore assigns the installation business assembly. The first purchase of

Overview: Builder mode: separates the construction of a complex object from its representation, so that different representations can be created during the same construction process. Usage: 1. When a complex object is createdAlgorithmIt should be independent from the components of the object and their assembly methods. 2. When the constructor must allow different representations of the object to be constructed. Class diagram: CodeStructur

Concepts of builder Mode The builder mode separates the construction of a complex object from its representation, so that different representations can be created for the same build process. That is to say, if we use the builder mode, users need

Builder mode separates the construction and representation of a complex object so that different representations can be created during the same construction process. Builder is the abstract interface specified for each part of a product object; Concretebuilder is a specific builder. It implements the builder interfac

【Example of application scenarios of builder Mode] For example, if you are playing the "need for speed" game, the map on each level will be ever-changing. Simply put, the map will be divided into Sunny Days and cloudy days, when creating a map, you need to render the scene on the map on a sunny or cloudy day, such as the sky, tree, house, and road surface. This process is fixed, each time you create a new map, you need to perform the rendering. This i

The hierarchical structure of the Builder call (order) brings us to an interesting question, or to a dilemma. What happens if you are currently in the inner of a builder and call a dynamic binding method for the object that you are building up? Inside the original method, we can imagine exactly what happens-a dynamically bound call is parsed during run time because the object does not know whether it belon

Does the android sub-thread really fail to update the ui? The android thread updates the ui. In actual development, the sub-thread cannot update the ui, but in the test code, we can update the ui in the sub-thread, for example: A textview performs findviewbyid in the oncreate lifecycle method. Then, write a thread and

Every WEB designer has worked UI design, and even so, the scarcity of resources, narrow horizons, and often make their painstaking work is not optimistic, in fact, UI design does not need to be behind closed doors, many UI elements are generic.

Transferred from: http://www.cnblogs.com/moonz-wu/archive/2011/01/11/1932473.htmlThe builder pattern is defined in design mode as a pattern for building complex objects that often require multiple-step initialization or assignment to complete. So, in the actual development process, where do we fit the builder model? It is a good practice to use builder mode inste

[Mode overview] ---------- by xingooPattern intent The creation of an object is very complex. In order to distinguish the building process from the use process, it is separated. A ctor class is used to create objects. Builder specifies the creation process.Mode Structure Builder abstracts the builder interface and standardizes the construction of each component.
