去，在struct中如何引用当前对象（在Java和C ++中这样）？

Question

What is go's this (or self in python) construct?

type Shape struct {
    isAlive bool
}

func (shape *Shape) setAlive(isAlive bool) {

}

in the setAlive function how do I do this.isAlive = isAlive; ?

Answer 1

In your example, shape is the receiver. You could even write it like this:

func (this *Shape) setAlive(isAlive bool) {
    this.isAlive = isAlive
}
