callback()

virtual void dx::event< kernel >::callback ( )

inlinevirtualinherited

The default implementation is based on event<user> which is signalled when triggered via callback() from kernel. This is to achieve compatibility with Windows events. Its probably more adequate to overwrite callback() and do the work here if feasible.

\ indicate the value is in transition - does not have the new value yet

server: handle synchronous and asynchronous value updates and initialization lock: lock promoted value from access during update value: new value (if in transition) current: current value to allow discarding update and reverting to current value if update is not permitted

it needs to handle these case: not initialized and not in transition: initialze and commit the value not initialized and in transition: if dependent on external settings initialize a temporary and compare it with the new value and update the external setting if required make sure to commit the new value so listeners get notified either synchronously or asynchronously by external notification initialized and in transition: update external settings if any and make sure to commit the new value so listeners get notified either synchronously or asynchronousl by external notification

server will not be called with this state: initialized and not in transation

for synchronous operation: move lock to commit for asynchronous operation: store lock and at asynchronous response restore and move lock to commit

bool dx::promoted< ::DWORD >::transient
