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; ?
In your example, shape is the receiver. You could even write it like this:
func (this *Shape) setAlive(isAlive bool) {
this.isAlive = isAlive
}
Go's method declarations have a so called receiver in front of the method name. In your example it's (shape *Shape). When you call foo.setAlive(false) foo is passed as shape to setAlive.
So basically the following is syntactical sugar
func (shape *Shape) setAlive(isAlive bool) {
shape.isAlive = isAlive
}
foo.setAlive(false)
for
func setAlive(shape *Shape, isAlive bool) {
shape.isAlive = isAlive
}
setAlive(foo, false)
