Detailed Description
Helper for type correct assignment of incidences via pointers.
This class provides a way of correctly assigning one incidence to another, given two IncidenceBase derived pointers. It effectively provides a virtual assignment method which first type checks the two pointers to ensure they reference the same incidence type, before performing the assignment.
Usage example:
KCal::Incidence *currentIncidence; // assume this is set somewhere else KCal::Incidence *updatedIncidence; // assume this is set somewhere else KCal::AssignmentVisitor visitor; // assign if ( !visitor.assign(currentIncidence, updatedIncidence) ) { // not of same type }

bool AssignmentVisitor::assign | ( | IncidenceBase * | target, |
const IncidenceBase * | source | ||
) |
Assigns the incidence referenced by source
to the incidence referenced by target
, first ensuring that the source
incidence can be cast to the same class as the target
incidence.
Basically it is a virtual equivalent of
*target = *source
- Parameters:
-
target pointer to the instance to assign to source pointer to the instance to assign from
- Returns:
false
if the two objects are of different type
