Implements mongo::BackgroundJob.
Implemented in mongo::task::Server.
| virtual void mongo::task::Task::run | ( | ) | [private, virtual] |
define this to do your work. after this returns, state is set to done. after this returns, deleted if deleteSelf true.
NOTE: if run() throws, the exception will be caught within 'this' object and will ultimately lead to the BackgroundJob's thread being finished, as if run() returned.
Implements mongo::BackgroundJob.
