Design Mode-Bridge ModeBridge: separates abstract and implementation parts so that they can all change independently. Understanding: To solve the problem of changing an object and affecting multiple objects, we need to abstract specific objects so that the coupling between objects and change factors can be reduced and the maintainability and scalability of the system can be improved. For example, the mobile
JavaScript: Bridge Mode in Design ModeIntroduction
Bridge separates abstract parts from their implementations so that they can all change independently.Body
The bridge mode is most commonly used in event monitoring. first look at the Code:
addEvent(element, 'click', getBeerB
The original understanding of bridge mode is not very deep, the feeling and build pattern is very similar, and today saw gang of four about bridge mode, some new understanding

Whether it's a new hardware platform or a new OS, everyone can focus on their own fields. That is, the external world is greatly changed, but the impact on this model is very small.

Problem focus: in the previous section, we talked about the object structure mode. The main idea is the combination of objects. And has access to a typical adapter mode. This section introduces a common bridge mode. Its main idea is to separate the abstract part from the implementation part, so that the abstract part i

Synthesis/Aggregation multiplexing principle (CARP):
Instead of using class inheritance, the composition/aggregation is preferred.
Aggregation represents a weak "owning relationship", which reflects that a object can contain a B object, but the B object is not part of a object.
Synthesis represents a strong "ownership relationship" that embodies a strict part-to-whole relationship, as part of the life cycle of the whole.
Its benefits: prioritizing the composition/aggregation of objects will

You do not want to have a fixed binding relationship between the abstraction and its implementation section. For example, this may be because the implementation part of the program run time should be selectable or switched.2. The abstraction of a class and its implementation should
OverviewBridge mode is a very practical structure design mode, if a class in a software system has two independently changing dimensions, this mode can separate the two dimensions, so that the two can be independently expanded, so that the system more in line with the "single responsibility principle." Unlike a multi-tier inheritance scheme, it designs two indepe
Bridge Mode ):
Definition: decouples abstraction from its implementation so that they can all change independently. (Note: The implementation here refers to the abstract class and its derived classes used to implement their own objects)
Implementation: encapsulate the implementation in an abstract class. Contains an implementation handle in the abstract base class to be implemented.
Structure:
The implemen
inherit from the window class, but aggregate windows or gtkwindow to implement the window function. In this way, will the abstraction and implementation be separated? Can it be changed independently?
C. Question:
(1) Why is the bridge mode?
The abstract part and the implementation part are not inherited, but the abstract Part aggregates the implementation part. Such a link is called a

Whether it's a new hardware platform or a new OS, everyone can focus on their own domain. That is, the external changes are very large, but the impact on this model is very small.

Written before: The meaning of the design pattern is to solve the actual design problems, the reason why the poor understanding is because there is no personal experience, so to keep learning practical thinking.Bridge is translated as bridging. Since there must be two objects bridged for bridging. This article intends to analyze the bridging mode from three aspects.1. What are the two objects bridged? 2. How to Br
Bridging Mode: separates object from specific behaviors and features so that they can change independently. Object is only an abstract concept. For example, "circle" and "Triangle" are under the abstract "shape", while "circle" and "Triangle draw" are under the "Drawing" Class of implementation behavior, then, "Drawing" is called by "shape ". "Shape" becomes an inheritance system, and "Drawing" becomes another inheritance system. The relationship betw
