If you are invited to a private event, you get full access to it, as you would if it were not private. Only restriction is: other people you gave access to your private events, still cant read the event, as long as they have no direct private grant from the owner of the event.

/**
|
|
* Class to access and manipulate all calendar data
|
|
*
|
|
* At the moment this class partialy uses the "old" bocalendar class.
|
|
* As the calendar rewrite proceeds, these references will be removed.
|
|
*
|
|
* Note: All new code should only access this class and not bocalendar!!!
|
|
*
|
|
* If you need a function not already available in bocal, please ask RalfBecker@outdoor-training.de
|
|
*
|
|
* The new UI, BO and SO classes have a strikt definition, in which time-zone they operate:
|
|
* UI only operates in user-time, so there have to be no conversation at all !!!
|
|
* BO's functions take and return user-time only (!), they convert internaly everything to servertime, because
|
|
* SO operates only in server-time (please note, this is not the case with the socalendar*-classes used atm.)
|
|
*
|
|
* As this BO class deals with dates/times of several types and timezone, each variable should have a postfix
|
|
* appended, telling with type it is: _s = seconds, _su = secs in user-time, _ss = secs in server-time, _h = hours
|
|
* The dates returned by this class are always arrays with the following keys (subset of the array used by datetime):
|
|
* year, month, day (not mday!), hour, minute (not min!), second (not sec!), raw (timestamp) and full (Ymd-string)
|
|
*
|
|
* All new BO code (should be true for eGW in general) NEVER use any $_REQUEST ($_POST or $_GET) vars itself.
|
|
* Nor does it store the state of any UI-elements (eg. cat-id selectbox). All this is the task of the UI class !!!
|
|
*
|
|
* All permanent debug messages of the calendar-code should done via the debug-message method of the class !!!
