Detailed Description

template<typename T>
class RTT::internal::ConnOutputEndpoint< T >

This is a channel element that represents the output endpoint of a connection, i.e. the part that is connected to the InputPort. In the RTT, connections are always created from input towards output. So this class is typically first created of the channel element chain and attached to the input port. Then we build further towards the outputport. Imagine a spider attaching a thread at one wall and moving along to the other side of the wall.

Constructor & Destructor Documentation

template<typename T>

RTT::internal::ConnOutputEndpoint< T >::ConnOutputEndpoint	(	InputPort< T > *	port,
		ConnID *	output_id
	)		`[inline]`

Creates the connection end that represents the output and attach it to the input.

Parameters:

port	The start point.
output_id	Each connection must be identified by an ID that represents the other end. This id is passed to the input port port.

Returns:

Member Function Documentation

template<typename T>

virtual bool RTT::internal::ConnOutputEndpoint< T >::data_sample ( typename base::ChannelElement< T >::param_t sample ) [inline, virtual]

Definition at line 128 of file ConnOutputEndPoint.hpp.

template<typename T>

virtual void RTT::internal::ConnOutputEndpoint< T >::disconnect ( bool forward ) [inline, virtual]

Performs a disconnection of this channel's endpoints. If forward is true, then the disconnection is initiated by the input endpoint. Otherwise, it has been initiated by the output endpoint.

Reimplemented from RTT::base::ChannelElementBase.

Definition at line 102 of file ConnOutputEndPoint.hpp.

template<typename T>

virtual base::PortInterface* RTT::internal::ConnOutputEndpoint< T >::getPort ( ) const [inline, virtual]

Gets the port this channel element is connected to.

Returns:: null if no port is connected to this element, the port (or a proxy representing the port) otherwise.

Reimplemented from RTT::base::ChannelElementBase.

Definition at line 133 of file ConnOutputEndPoint.hpp.

template<typename T>

bool RTT::internal::ConnOutputEndpoint< T >::inputReady ( ) [inline, virtual]

Called by the connection factory to check that the connection is properly set up. It is called when the channel is complete, so we can register ourselves on the port side now

Before that, the channel might not be complete and therefore having the input port read on it would lead to crashes

Reimplemented from RTT::base::ChannelElementBase.

Definition at line 87 of file ConnOutputEndPoint.hpp.

template<typename T>

virtual bool RTT::internal::ConnOutputEndpoint< T >::signal ( ) [inline, virtual]

Signals that there is new data available on this channel By default, the channel element forwards the call to its output

Returns:: false if an error occured that requires the channel to be invalidated. In no ways it indicates that the sample has been received by the other side of the channel.

Reimplemented from RTT::base::ChannelElementBase.
