virtual bool RTT::base::PortInterface::addConnection	(	internal::ConnID *	cid,
		ChannelElementBase::shared_ptr	channel,
		ConnPolicy const &	policy = `ConnPolicy()`
	)

pure virtual

Adds a user created connection to this port.

This is an advanced method, prefer to use connectTo and createStream.

Implemented in RTT::corba::RemoteInputPort, RTT::base::InputPortInterface, RTT::corba::RemotePort< base::InputPortInterface >, RTT::corba::RemotePort< base::OutputPortInterface >, and RTT::base::OutputPortInterface.

virtual PortInterface* RTT::base::PortInterface::antiClone ( ) const

pure virtual

Create a local clone of this port with the same name.

If this port is a local port, this is an object of the inverse direction (read for write and write for read), and same name. If this object is a remote port, then it is a local port of the inverse direction and with the same name.

Implemented in RTT::OutputPort< T >, RTT::InputPort< T >, RTT::corba::RemoteInputPort, and RTT::corba::RemoteOutputPort.

virtual PortInterface* RTT::base::PortInterface::clone ( ) const

pure virtual

Create a local clone of this port with the same name.

If this port is a local port, this is an object of the same type and same name. If this object is a remote port, then it is a local port of the same type and same name.

Implemented in RTT::OutputPort< T >, RTT::InputPort< T >, RTT::corba::RemoteInputPort, and RTT::corba::RemoteOutputPort.

virtual bool RTT::base::PortInterface::connected ( ) const

pure virtual

Returns true if this port is connected.

Implemented in RTT::base::InputPortInterface, RTT::base::OutputPortInterface, RTT::corba::RemotePort< base::InputPortInterface >, and RTT::corba::RemotePort< base::OutputPortInterface >.

Referenced by RTT::corba::CDataFlowInterface_i::_default_POA(), createPortObject(), and setName().

bool PortInterface::connectedTo ( PortInterface * port )

virtual

Returns true if this port is connected to the given port.

Definition at line 67 of file PortInterface.cpp.

References cmanager, and RTT::internal::ConnectionManager::connectedTo().

Referenced by RTT::internal::ConnFactory::createConnection().

virtual bool RTT::base::PortInterface::connectTo	(	PortInterface *	other,
		ConnPolicy const &	policy
	)

pure virtual

Connects this port with other, using the given policy.

Unlike OutputPortInterface::createConnection, other can be the write port and this the read port.

Returns: true on success, false on failure

Implemented in RTT::base::OutputPortInterface, and RTT::base::InputPortInterface.

virtual bool RTT::base::PortInterface::connectTo ( PortInterface * other )

pure virtual

Connects this port with other, using the default policy of the input.

Unlike OutputPortInterface::createConnection, other can be the write port and this the read port.

Returns: true on success, false on failure

Implemented in RTT::base::OutputPortInterface, and RTT::base::InputPortInterface.

virtual bool RTT::base::PortInterface::createConnection	(	internal::SharedConnectionBase::shared_ptr	shared_connection,
		ConnPolicy const &	policy = `ConnPolicy()`
	)

pure virtual

Connects this port to an existing shared connection instance.

Implemented in RTT::corba::RemoteInputPort, RTT::base::InputPortInterface, and RTT::base::OutputPortInterface.

Service * PortInterface::createPortObject ( )

virtual

Create accessor Object for this Port, for addition to a TaskContext Object interface.

Reimplemented in RTT::OutputPort< T >, and RTT::InputPort< T >.

Definition at line 79 of file PortInterface.cpp.

References RTT::Service::addSynchronousOperation(), connected(), disconnect(), getName(), RTT::DataFlowInterface::getOwner(), and iface.

Referenced by RTT::InputPort< T >::createPortObject(), RTT::DataFlowInterface::createPortObject(), and RTT::OutputPort< T >::createPortObject().

virtual bool RTT::base::PortInterface::createStream ( ConnPolicy const & policy )

pure virtual

Creates a data stream from or to this port using connection-less transports.

Typically, policy.transport and policy.name_id must be properly filled in such that the data stream can be set up and input and output port can find each other. You need to call this method on two ports (input and output) using the same transport and (probably) same name_id.

Parameters

policy The connection policy describing how the stream must be set up.

Implemented in RTT::OutputPort< T >, RTT::InputPort< T >, RTT::corba::RemotePort< base::InputPortInterface >, and RTT::corba::RemotePort< base::OutputPortInterface >.
