Asynchronously retrieves the value of this object from the server and passes it to the provided callback function.
Usage
Returns
Geometry.evaluate(callback)
Argument
Type
Details
this: computedobject
ComputedObject
The ComputedObject instance.
callback
Function
A function of the form function(success, failure), called when the server returns an answer. If the request succeeded, the success argument contains the evaluated result. If the request failed, the failure argument will contains an error message.
