device resource api

hi
while im updating device i trace code,but the put method in deviceresource class(api) does not invoke .so i dont understand how it works?

You're clearly missing something. The code should be invoked.

when i click save buttom , it goes to constructor of DeviceResource class, then it goes to put method in BaseObjectResource Class, after that it get back to constructor of DeviceResource class and finally it goes to get method of DeviceResourcs class. but put method in DeviceResourcs class does not invoke in this loop.

DeviceResource does not override the PUT method, so it is correct that the implementation in BaseObjectResource is called. Sounds like everything is working as expected.

so what is the role of put method in DeviceResource class? isnt it api of update device?

You mean updateAccumulators? It's to update accumulators.

yes exactly.

what is accumulators.?

Accumulators are things that accumulate values. Currently we have distance and engine hours accumulators.

I am also confused with DeviceResource.java there is no POST method, first I think PUT method is doing work as POST. When I removed the all PUT codes from file.I recompile and replace all files. after that add device function are working. How this possible.

Where is the code for adding device where is POST method for add device.

Exactly the api address is api/devices but the invoked method in parent class

The api implement in baseresource class.
