Class that model connections between signals and slots.
This class model the concept of signal and slot connection i.e. the knowledge a signal has about who it has to notify whenever the client invoke the Emit( ) method on a Signal object. Also it becomes the passage through the Slot::Unbind method can access the bound signals to disconnect them. Each time a Signal and a Slot are bound together a Connection object is created, being tagged by a Global Unique IDenfier ( GUID ). These GUID's are reused whenever the Connection object holding it is destroyed.

| SigSlot::Connection::Connection | ( | ) |
Default constructor.
Initializes the Connection so to be nil. This constructor should not be used from the client: its existence is justified for allowing to have Connection objects inside STL containers
Definition at line 26 of file Connection.cxx.
References NULL.
| SigSlot::Connection::Connection | ( | tConnectionId | id, | |
| Signal * | connectedSignal | |||
| ) |
Explicit constructor.
Initializes the object with a GUID and a reference to the Signal the Slot is being connected to.

| SigSlot::Connection::Connection | ( | const Connection & | s | ) |
| SigSlot::Connection::~Connection | ( | ) |
Destructor.
When connections are destroyed it is checked that the connection is active, if that is the case then the Signal is notified about not calling anymore the involved slot object.

| tConnectionId SigSlot::Connection::GetID | ( | ) | const [inline] |
Accessor to the GUID.
Accessor for getting the GUID hold by the Connection object.

| Connection & SigSlot::Connection::operator= | ( | Connection & | s | ) |
Assignment operator.
Copies the Connection object provided, keeping the GUID and the reference to the signal. To avoid owning problems, the source Connection object is marked as 'disabled'.
