Salesforce Platform Developer II 認定 PDII 試験問題 (Q130-Q135):

質問 # 130
Universal Containers stores user preferences in a hierarchy custom setting, user Prefs_c, with a checkbox field, show _help co. Company-level defaults are stored at the organizational level, but may be overridden at the user level. If a user has not overridden preferences, then the defaults should be used.
How should the show_Help_ c preference be retrieved for the current user?

A. Boolean show =
User Prefs c.getValues(UserInfo.getUserid{)).Show_Help c;
B. Boolean show = User_Prefs_c.getlnstance(].Show Help c;
C. Boolean show = User_Prefa_ c.getValuea().Show_Help_ co;
D. Boolean show = User Prefs_c.show Melp_c;

正解：A

解説：
The correct way to retrieve the show_Help_ c preference for the current user is to use the User Prefs c.getValues(UserInfo.getUserid{)).Show_Help c statement. This statement will return the user-level value of the show_Help_ c field for the current user, if it exists, or the org-level value, if it does not. The User_Prefa_ c.getValuea().Show_Help_ co statement will always return the org-level value, regardless of the user. The User_Prefs_c.getlnstance(].Show Help c statement will return the user-level value of the show_Help_ c field for the current user, if it exists, or null, if it does not. The User Prefs_c.show Melp_c statement will cause a compile-time error, as the show_Help_ c field is not a static property of the User Prefs_c class.
