Google Maps API v3: How to evacuate all markers?

In Google Maps API v2, if I wanted to remove all the map markers, I could simply do:

map.clearOverlays();

How do I do this in Google Maps API v3?

Looking at the Reference API, it's unclear to me.

google.maps.Map.prototype.markers = new Array();

google.maps.Map.prototype.addMarker = function(marker) {
    this.markers[this.markers.length] = marker;
};

google.maps.Map.prototype.getMarkers = function() {
    return this.markers
};

google.maps.Map.prototype.clearMarkers = function() {
    for(var i=0; i<this.markers.length; i++){
        this.markers[i].setMap(null);
    }
    this.markers = new Array();
};

I don't think there is one in V3 so I used the above custom implementation.

Same problem. This code doesn't work anymore.

I've corrected it, change clearMarkers method this way:

set_map(null) ---> setMap(null)

google.maps.Map.prototype.clearMarkers = function() {
    for(var i=0; i < this.markers.length; i++){
        this.markers[i].setMap(null);
    }
    this.markers = new Array();
};

Simply do the following:

I. Declare a global variable:

var markersArray = [];

II. Define a function:

function clearOverlays() {
  for (var i = 0; i < markersArray.length; i++ ) {
    markersArray[i].setMap(null);
  }
  markersArray.length = 0;
}

OR

google.maps.Map.prototype.clearOverlays = function() {
  for (var i = 0; i < markersArray.length; i++ ) {
    markersArray[i].setMap(null);
  }
  markersArray.length = 0;
}

III. Push markers in the 'markerArray' before calling the following:

markersArray.push(marker);
google.maps.event.addListener(marker,"click",function(){});
