Joint::GetType() in Gazebo 1.x

edit

I am porting a Gazebo 0.x plug-in to Gazebo 1.x. In the 0.x version, I had some code like this:

if (joint->GetType() == Joint::HINGE) doSomething();

For the 1.x plug-in, I replaced the code with this:

if (joint->GetType() == Joint::HINGE_JOINT) doSomething();

However, doSomething was never called. I ended up having to use this:

if (joint->GetType() == Joint::JOINT | Joint::HINGE_JOINT) doSomething();

Is plug-in code now supposed to test individual bits of the value returned by Joint::GetType()? For example, should the plug-in now do this:

if (joint->GetType() & Joint::HINGE_JOINT) doSomething();
