Member Function Documentation

virtual bool file_watcher::EventHandler::Handle ( const std::string &  file_path, Event  event, bool *  clear_handler  )

pure virtual

Handle function called per event

Parameters

file_path	- the path of the file this event corresponds to
event	- the type of event
clear_handler	- (output) set this to true to have the event handler remove from the loop after this call

Should return false in case of failure.

Setting the clear_handler parameter to false means that the FileWatcher object will attempt to re-register the handler for the same file name in the case a file was delete - useful for continuously watching a file which may be deleted and recreated

Implemented in ResolvConfEventHandler.

Referenced by file_watcher::FileWatcherInotify::RunEventLoop(), and file_watcher::FileWatcherKqueue::RunEventLoop().
