def requestHandler(request):
"""
This function process the Request object from the server
and generates response data by interacting with the data-layer.
This response data is then wrapped in a Response object
which is returned to the network server.
Functionality:
If the request is the action is in Designation Master,
the JSON object is converted to Designation object of all_common module
which is further converted to Designation object of data-layer.
This object is passed to the appropriate data-layer method and thus retrieve data
This data is again converted to JSON string and the response object is created.
This processed object is then returned.
In another case, if the request is in Employee Master,
the JSON object is converted to Employee object of all_common module
which is further converted to the Employee object of data-layer.
This object is passed to the appropriate data-layer method and thus retrieve data
This data is again converted to JSON string and the response object is created.
This processed object is then returned.
To obtain a convertible Designation/Employee object,
it often uses Wrapper and List Handler class.
While if an exception gets raised it uses ExceptionHandler class to be processed
which can be wrapped in the Response object.
Arguments:
request(Request): it is the object that wraps the data required
to understand the request sent by the client and to process the response.
Raises:
DataLayerError:
if some error occurs at the data layer, it raises DataLayerError.
Return Value:
returns the Response object.
