class | ConnectionBase |
The base signal class which stores connection objects.
It implements real-time management of connections, such that connection/disconnetion of a handler is always thread-safe and real-time.

virtual |
Deletes this Signal and will destroy all connections and handles of this object.
It is not necessary to call disconnect() or disconnect() prior to destroying a SignalBase.

References destroy().

pure virtual |
Returns the arity (the number of arguments) of this signal.
Implemented in RTT::internal::OROCOS_SIGNAL_N< R, SlotFunctionT >.

void RTT::internal::SignalBase::destroy | ( | ) |
Destroys all connections.
This will destroy all connections of this Event. All Handles will be disconnected and unable to reconnect.

void RTT::internal::SignalBase::disconnect | ( | ) |
Disconnects all connections.
All Handles will be disconnected, but able to reconnect.

void RTT::internal::SignalBase::reserve | ( | size_t | conns | ) |
Reserves memory for a number of connections.
Use this method to efficiently reserve memory for possible connections. If not used, the event will reserve memory in batch, depending upon demand. This does not impair/influence real-time performance, only memory efficiency.
conns | The number of connections to reserve memory for. |
