No default value assigned by code generation

[acloudiator]

in some cases, described below, yang default parameter is not taken into account by code generation.

Case1 (working):

leaf pathcost {
  type int32;
  default 1;
  description "Cost of this route";
  router:cli-example "10";
}

int32_t m_pathcost;
m_pathcost = 1;

Case2 (not working):

leaf pathcost {
  type uint32;
  default 1;
  description "Cost of this route";
  router:cli-example "10";
}

//No default value is generated by codegen
uint32_t m_pathcost;

Case3 (not working):

leaf pathcost {
  type string;
  default "1";
  description "Cost of this route";
  router:cli-example "10";
}

std::string m_pathcost;
m_pathcost = 1; // it should be a string, so "1"

Case4 (not working):

leaf pathcost {
  type uint8;
  default 1;
  description "Cost of this route";
  router:cli-example "10";
}

uint8_t m_pathcost;
// no default value is set

The string case has been fixed: a0059af.

The cases for unsigned integers are more difficult to solve because this is a issue in swagger-codegen base code: swagger-api#6929.

A workaround for now is to use signed integers instead of unsigned.

I think the problem is in swagger-core module used by swagger-codegen.
While properties of type intX are converted to an object of class io.swagger.models.properties.IntegerProperty
that has a getDefault() method, all other integer properties (unsigned and all the ones derived from an integer using a typedef) are converted to an instance of io.swagger.models.properties.BaseIntegerProperty
that lacks the getDefault() method.
Currently I don't know how to overcome this problem.
