void Vision::DFK51BG02H::Task::onRequestActivation ( void  )

inlinevirtual

Called when an external activation request is received.

Derived classes that need to perform extra steps to prepare normal execution should replace the default behaviour of immediate activation with calls to activate() when the request is completed or activationFailed() if the request cannot be honoured.
