Dynamically detecting map layer service type

AndyStewart1

I'm looping through map layers. How do I determine which services are dynamic vs. tiled vs. image?

The layer object in the Javascript API doesn't seem to have a TYPE property. Am I wrong?

Use a layer's has a declaredClass property to figure out what kind of layer it is. For instance, declaredClass for a tiled layer is "esri.layers.ArcGISTiledMapServiceLayer".

Hi Derek,

Could you please help provide some link to the documentation that states the information for declaredClass or if there are any more methods available. I tried to search through the API documentation but was not able to find anything related to layer.declaredClass

Although it works as a great solution to my issue I am just curious to know how does this work and what other methods or properties are available.

Thanks in advance!!!!

Found the info.

http://livedocs.dojotoolkit.org/dijit/info#common-attributes-of-dijits

declaredClass - this is actually a relic of dojo.declare, which is how widgets are defined. The declaredClass is a string equal to the fully qualified name of the widget class.

require(["dijit/Dialog"], function(Dialog){ var myDialog = new Dialog({ title:"foo" }, "bar"); myDialog.declaredClass == "dijit/Dialog" // true });

Thanks,

Manish
