Design Mode note generator (Builder) mode Builder // Builder mode --- object Creation Mode /* 1: Intention: separates the construction of a complex object from its representation, so that different representations can be created during the same construction process. 2: Motivation 3: Applicability: 1> when creating complex objects, algorithms should be independ

Design Pattern Series (iii) the factory model is described in the article, the factory method model and the abstract factory pattern are introduced. This paper mainly introduces the design pattern of builderOverviewIn the software system, sometimes faced with the creation of "a complex object", it is usually composed of the child objects of each part by a certain algorithm; Because of the change of requirements, the various parts of this complex object often face drastic changes, but the algorit

Freely scale your project: Builder mode, extended builder Because a complex object has many components, such as a car, a wheel, a steering wheel, an engine, and various small parts, how can we assemble these components into a car, this assembly process is long and complex. In this case, in order to hide implementation details from the outside during the construction process, you can use the

Builder mode Separating the construction of a complex object from its representation allows the same build process to create different representations. OverviewWhen the system is ready to provide users with an internally complex object, you can use the generator patt

Builder mode Definition: separates the construction of a complex object from its representation so that the same build process can create different representations.The builder pattern is a step-by-step creation of a complex object that allows the user to build them only by specifying the type and content of the complex objects. The user is not aware of the specifics of the build internals. The

Key points of the builder mode: The builder mode is mainly used"Build a complex object in steps ". In this case, "step-by-step" is a stable multiplication, while all parts of complex objects change frequently. The builder mode mainly dealsFrequent demand changes for "various parts of complex objects. ItsDisadvantage:It is difficult to cope with changes in the dem

This article is "effective Java" Reading notes, because it is a Java advanced book, it is inevitable that there will be an understanding of the deviation, if there is a mistake, very welcome to criticize, I am greatly appreciated. What is a builder (Builder), a classmate who has been interviewed may have been asked to distinguish between string and StringBuffer and StringBuilder, and here is the StringBuild

The builder pattern is somewhat similar to the previous abstract factory pattern, but more powerful than the abstract factory pattern, the builder pattern can be seen as two parts, one builder, and the other is that the basic idea of Director,builder is the abstract factory, While the director exists to make the use of

Idea: Since the interstellar picture is made up of several parts: the map (the terrain and the minerals), the building, the troops. Then we think of them as parts, assembled to be the final product (the whole picture). Builder (Builder) mode example: The code is as follows Copy Code Specification of interfaces for manufacturing individual parts Interface

The factory class pattern provides the pattern of creating a single class, while the builder pattern is to centralize the various products to manage, to create composite objects, so-called composite objects that refer to a class that has different properties, in fact the builder pattern is the combination of the previous abstract factory pattern and the last Test. Let's look at the code:As before, a sender
