how to retrieve gMarkers from google maps object

[abbood]

angular-google-maps abstracts the process of creating google markers (ie we don't do it directly via new google.maps.Marker({...});).. that said, there isn't a way for us to simply retrieve the markers pertaining to a google map object nor can we create our own array to store a reference to these markers for later usage (see here)

Is there a way for us to retrieve the gMarkers pertaining to the google map object? @nmccready

Yeah something could be added like a control object like Map has. I agree this should be there. I think this may be a dupe issue as well.

@nmccready sounds like a good idea.. this feature is actually blocking me and i would like to contribute (by doing a pull request?).. in a sentence or two can you point me in the right direction? i looked at the markers directive code and it pulls its data from MarkersParentModel.. I'm kind of lost, in a few sentences can you point me in the right direction?

Yes this is actually easy. First look at how control is implemented in the map directive. All will be doing is slapping methods onto the this control object if it is available. The Markers directive has access to the MarkersParentModel. First MarkersParentModel reference will need to be saved off to a reference attribute.

link: (scope, element, attrs, ctrl) =>
         @parentModel    = new MarkersParentModel(scope, element, attrs, ctrl, @$timeout)

Therefore you should apply a method like:

#this is all scope, model and gmarker which are linked together and it is a PropMap object, need array call markerModels.values()
control.getChildMarkers = @parentModel.markerModels
#one of several ways as it could be derived from ChildMarkers, comes from either a MarkerManager or ClusterMarkerManager
control.getGMarkers = @gMarkerManager.getGMarkers()

FYI, I am basing this off develop branch

Please do PR against develop.

Notice getGMarkers() was just added in commit above.

ok excellent! i'll take a look at it shortly.. btw what does the @ mean (ie @parentModel.markerModels)?

[nmccready]

It means this . It also can be a shortcut without the need of using or declaring self.

Example:

class Foo
  constructor: -> #special function where @, 'this' refers to the class instance . It is special because it uses -> and => (fatarrow)
    @junk = "crap"

   getJunk: =>
     @junk # @ is interpreted as _this, which normally would be self in js or using apply

   getJunkInvalid: ->
     @junk # exception junk is undefined because in this context @ is just this, which is the function instance

Make sense?

Ah i see.. I forgot you are using coffeescript.. So I'm guessing your source code is all created using coffeescript then compiled and distributed as js under the dist folder right? Then I should start looking at the coffeescript to understand the code.. It will be cleaner that way

[nmccready]

Correct
