9 | """This class abstracts a D* user. |
10 | This object goes around the limitations of current D* API and will | |
11 | extract user data using black magic. | |
12 | However, no chickens are harmed when you use it. | |

14 | The parameter fetch should be either 'posts', 'data' or 'none'. By |
15 | default it is 'posts' which means in addition to user data, stream | |
3cf4514e MM |
16 | will be fetched. If user has not posted yet diaspy will not be able |
17 | to extract the information from his/her posts. Since there is no official | |
18 | way to do it we rely on user posts. If this will be the case user | |
7b99bf75 | 19 | will be notified with appropriate exception message. |
3cf4514e | 20 | |
7b99bf75 JR |
21 | If fetch is 'data', only user data will be fetched. If the user is |
22 | not found, no exception will be returned. | |
23 | ||
24 | When creating new User() one can pass either guid, handle and/or id as | |
25 | optional parameters. GUID takes precedence over handle when fetching | |
26 | user stream. When fetching user data, handle is required. | |
