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".

That was the ticket.  Thanks!

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!!!!

Best Regards,

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,
