IProviderHints (Eclipse Platform API Specification)

```
public interface IProviderHints
```
Sometimes it might be desirable to pass some context information to the password provider modules (such as a need to run without UI prompts). Below are some pre-defined options that can be used to exchange information between creators of secure storage and password providers.
Options can be specified as an entry in the options map SecurePreferencesFactory.open(java.net.URL, java.util.Map).
Password provider modules are advised to take into consideration those options when applicable; note, however, that it is up to specific module to decide if (and how) they would respond to an option.
The set of options is open-ended and not limited to options specified below; modules can choose to process additional hints.
