What we do is first expand the master instance into the set of generate instances. Then we merge the overridden instances, taking into account THISANDFUTURE and THISANDPRIOR. @param componentSet: the set of components that are to make up the recurrence set. These MUST all be components with the same UID and type, forming a proper recurring set. @param limit: L{DateTime} value representing the end of the expansion. t VEVENTs RECURRENCE-IDt VTODOt VJOURNALs/ VJOURNAL recurrence expansion not supported yett VFREEBUSYt VAVAILABILITYt AVAILABLEN( R R t hasPropertyt appendt _addMasterEventComponentt _addMasterToDoComponentt NotImplementedErrort _addFreeBusyComponentt _addAvailabilityComponentt _addOverrideEventComponentt _addOverrideToDoComponent( R t componentSetR4 R5 t mastert overridesR ( ( s) /opt/cpanel-ccs/twistedcaldav/instance.pyt expandTimeRangesv sB c C sG | | j t | j � <t j rC t | j � t j k rC t � � n d S( sd Add the supplied instance to the map. @param instance: the instance to add N( R3 t strR R R t lenR ( R t instance( ( s) /opt/cpanel-ccs/twistedcaldav/instance.pyt addInstance� s !c C s� | j d k r� | j � ru | rC | j � | _ | j j t � n | j � | _ | j j t � | j j d � q� | | _ | | _ n | j | j f S( s� Change the limits to account for testing against DATE only values.
