Swagger generated Java Client has no overloaded calls, even though the query parameter is marked as optional












1















I'm introducing an optional "query parameter" (with default value) for one of my API endpoint ( i.e. /foo2) but hoping that existing API consumers don't have to make any changes in their application when they regenerate the java client stub from the new swagger file.



I was expecting that the generated java client will offer overloaded methods, to operate with and without a method parameter, so that my existing API consumers can work without any changes to their call. At the same time, they can switch to its more generic offering.



public void foo2Get() throws ApiException {
public void foo2Get(String type) throws ApiException {


But it generates ONLY the latter. I don't see the former.



At the same time, generated python client from same swagger throws a var arg and this way it more flexible and hence old and new offerings will work without any issues.



def foo2_get(self, **kwargs): 


(swagger sample used: attached)



** Description**
Is there a way to overcome this limitation with java code generator.
