Hello Dimuthu,
Iven't finalized my solution yet.
The first method requires the user to generate the library from the server
side instance. I will elaborate the advantages of this method later in this
thread. The major disadvantage is that the library has to be generated each
time the web services change.
For the second method, I think the best approach would be to return an
instance of a BaseResponse class ( that extends HashMap ). This class can
have a method that will clone the hashmap elements into a model class (
defined by the user ) according to the names of the data members.
Example :
After the method returns the HashMap ( which is the BaseWebResponse class )
will contain ("firstName"-> "Deepak", "lastName"-> "K", 'age'->25)
Suppose the user has defined a new model class called User { private String
firstName, lastName; private int age; //and the accessor methods included }
So the keys of the hashmap can directly correspond to the datamembers. We
can have a Object baseWebResponse.toClassOfType(Class classType) method
within the BaseWebResponse class which will do the conversion.
Thanks,
Deepak
