An example: ``` override fun onSatelliteClicked()...

# rx

[ubu]

An example:

override fun onSatelliteClicked() {
        mapSubject.take(1).subscribe(this::toggleSatelliteMode)
    }

[kioba]

this will trigger toggleSatelliteMode once only

oneClick -> oneAction

[ubu]

a new click event -> a new subscription.

that may sound crazy, I suppose 😀

[kioba]

myClickSubject.switchMap {
    mapSubject.take(1)
}.subscribe(this::toggleSatelliteMode, onError = {/* dont forget error ;) */ } )

override fun onSatelliteClicked() {
myClickSubject.onNext(1)
}

[kioba]

this way you don’t have to subscribe just once and each click will take one from the map.
@jeremy was right with using the SwitchMap

[kioba]

not sure if take(1) will unsubscribe from the myClickSubject or not
