public Gravatar()

Method Detail

getInstance

public static Gravatar getInstance()

If you want to have a email converted to a Gravatar URL, you need to get an instance of Gravatar. Static access is not the best solution, though it might seem to be the best solution to this simple task. Still, there will be some further improvement to this class. And a pure static approach will not be the only solution. Providing a Singleton Access is a good solution for now.

The Singleton instance of Gravatar.
