getDefaultpublic static ISecurePreferences getDefault()Returns default secure preferences.
The framework will attempt to open secure preferences in a user-specific location. As a result, the information stored can be shared among all programs run by the user. The location is determined as follows:
- "-equinox.keyring" command line arguments
- Java's "user.home" environment variable. On Windows system it usually corresponds to the %USERPROFILE% environment variable or determined as the parent of user's desktop folder. On Unix Java usually determines it from user's entry in the password file (commonly this corresponds to $HOME environment variable);
- if it fails, preferences will use configuration location of the current Eclipse instance.
- default instance of secure preferences,
nullif application was unable to create secure preferences using default location
openReturns a secure properties corresponding to the URL locations supplied. If URL is
null, a default location is used.
Note that while this method accepts URLs to account for future expandability of this API, at present the method only accepts "file" URLs that point to a directory. An
IOExceptionmight be thrown if unsupported URL is passed to this method.
Similarly to the rest of the Equinox, URLs passed as an argument must not be encoded, meaning that spaces should stay as spaces, not as "%x20".
location- URL pointing to the location of secure storage. At present only file URLs are supported. Pass
