Detailed Description
template<class T>
class RTT::DataConnection< T >
A local connection with a DataObject, which is used to connect multiple Ports to that DataObject.
- See also:
- ConnectionInterface why connection management is not thread-safe in this class.
Definition at line 55 of file DataConnection.hpp.
Constructor & Destructor Documentation
| RTT::DataConnection< T >::~DataConnection | ( | ) | [inline] |
The cleanup of DataConnection does nothing.
The only cause of deletion is that no Port holds a pointer to this connection (refcount becomes zero), hence, all readers and writers are already disconnected.
Definition at line 78 of file DataConnection.hpp.
Member Function Documentation
| virtual bool RTT::ConnectionInterface::addPort | ( | PortInterface * | p | ) | [virtual, inherited] |
Add a Port to the connection.
If this->connected(), also immediately connect p to this connection.
- Parameters:
-
p A port which wants to read or write data from this connection.
- Returns:
- true if p has the correct type and could be added
| virtual bool RTT::ConnectionInterface::connect | ( | ) | [virtual, inherited] |
Connect all readers and writers.
If a reader or writer is already connected to another connection, this method fails.
- Returns:
- false if at least one reader or writer was already participating in a connection or if connected()
| virtual BufferBase::shared_ptr RTT::DataConnection< T >::getBuffer | ( | ) | const [inline, virtual] |
Returns the buffer and its associated status of this connection, if this connection is buffered.
Otherwise, this returns the null pointer.
Implements RTT::ConnectionInterface.
Definition at line 84 of file DataConnection.hpp.
| std::string RTT::ConnectionInterface::getConnectionName | ( | ) | [inherited] |
Return the name of this connection if available.
- Returns:
- the name of the connection
| virtual DataSourceBase::shared_ptr RTT::DataConnection< T >::getDataSource | ( | ) | const [inline, virtual] |
Get a Data source representing the current value of this connection.
This function always returns a meaningful data source.
Implements RTT::ConnectionInterface.
Definition at line 80 of file DataConnection.hpp.
| PList RTT::ConnectionInterface::getPortList | ( | ) | [inherited] |
Accessibility method to return all the port list associated with this connection.
- Returns:
- the port list for this connection
| virtual bool RTT::ConnectionInterface::removePort | ( | PortInterface * | p | ) | [virtual, inherited] |
Remove a Port from the connection.
If this->connected(), also immediately disconnect p from this connection.
- Parameters:
-
p A port which no longer wants to read or write data from this connection.
- Returns:
- true if p was present.
| void RTT::ConnectionInterface::setConnectionName | ( | std::string | newConnectionName | ) | [inherited] |
Set a new name for this connection.
- Parameters:
-
newConnectionName The new name to be set for this connection.
| void RTT::ConnectionInterface::signal | ( | ) | [inherited] |
Signals that a new data sample has been written on this connection.
This is to be called by source ports when new data is written on the connection
