在Go中定义带有通道的接口

Question

Can I define an interface with a channel in Go? I would like to define an interface that would allow me to use objects of different types that would all have the same channel defined. EXE:

type I interface {
    chan Communications []byte
    otherMethod()
}

(This give syntax error: unexpected token chan. I tried a few different syntaxes and some googling with no avail.)

Answer 1

An interface does not hold data, it defines what something implements.

You could have a method that returns a channel. eg:

type I interface {
    getChannel() (chan []byte)
    otherMethod()
}

Please read up on interfaces. The tour would help.
