Description
Interface for PriorityDelegate and PriorityExpire. Very similar to AbstractDelegate but having two separate files (no inheritance) allows to have compile-time checks when registering an observer instead of run-time checks.
Member Summary
Member Functions: clone, notify, operator <, priority, target
Constructors

const AbstractPriorityDelegate & del
);

Member Functions
clone
virtual AbstractPriorityDelegate * clone() const = 0;
notify
virtual bool notify(
const void * sender,
TArgs & arguments
) = 0;
Returns false, if the Delegate is no longer valid, thus indicating an expire
operator <
bool operator < (
const AbstractPriorityDelegate < TArgs > & other
) const;
Operator used for comparing AbstractPriorityDelegates in a collection.
priority
int priority() const;
target
void * target() const;
