Talk about golang abstract methods
In the field of object-oriented programming, abstract method (Abstract Method) is an important concept. The opposite is Concrete Method. Abstract methods are generally used to define an interface, and the specific implementation is implemented by the class that implements this interface.
In the Go language, there is no concept of a class, but it supports interfaces, through which the concept of abstract methods is implemented.
First of all, the interface in Go language is composed of a set of methods (Method). These methods can be implemented by any type. For example, we define an interface:
type Animal interface { Move() }
This interface defines a Move method. Any type that implements this interface must implement the Move method. We can create a type called Cat:
type Cat struct {} func (c *Cat) Move() { fmt.Println("Cat is moving") }
The Cat type implements the Move method in the Animal interface.
Next we look at an example. In this example, we define a Car interface:
type Car interface { Engine() bool }
This interface defines an Engine method that returns a Boolean value. Any type that implements this interface must implement the Engine method.
Let’s create a type called Benz:
type Benz struct {} func (b *Benz) Engine() bool { return true }
The Benz type implements the Engine method in the Car interface and returns a true value.
In short, an abstract method is usually a convention that defines a specification and stipulates which methods must be implemented by a class that implements the specification. In Go language, we can define abstract methods through interfaces and create types that implement the interface to implement the functions of abstract methods.
Of course, in the Go language, we can also use other methods to implement the functions of abstract methods. Here we only use the interface method. For more implementation methods, please refer to relevant information.
