Detailed Description

template<typename T>
class RTT::corba::RemoteChannelElement< T >

Implements the CRemoteChannelElement of the CORBA IDL interface.

It converts the C++ calls into CORBA calls and vice versa. A read will cause a call to the remote channel (which is of the same type of this RemoteChannelElement) which returns an Any with the data. A similar mechanism is in place for a write.

bool ChannelElementBase::addInput ( shared_ptr const &  input)

Sets the new input channel element of this element or adds a channel to the inputs list.

Parameters
inputthe previous element in chain.
Returns
true if the input was set or false if this element does not support multiple inputs and the input is already set.

virtual bool RTT::corba::RemoteChannelElement< T >::channelReady ( base::ChannelElementBase::shared_ptr const &  caller,
ConnPolicy const &  policy,
internal::ConnID conn_id 
)
inlinevirtual

This is called on the output half of a new connection by the connection factory in order to notify the output side of the new connection and check if it is ready to receive data.

Each channel element has the responsibility to pass this notification on to the next, in the direction of the input. The ConnOutputEndPoint then calls back the inputReady() method in reverse direction to notify the output that the connection was successfully established.

Returns
false if a fatal connection failure was encountered and the channel needs to be destroyed.

void ChannelElementBase::clear ( )

Clears any data stored by the channel.

It means that ChannelElement::read() will return false afterwards (provided that no new data has been written on the meantime of course)

By default, the channel element forwards the calls to its input

template<typename T>
bool RTT::corba::RemoteChannelElement< T >::disconnect ( const base::ChannelElementBase::shared_ptr channel,
bool  forward 
)
inlinevirtual

Performs a disconnection of a single input or output endpoint.

If forward is true, then the disconnection is initiated by the input endpoint and channel must be a connected input. Otherwise, it has been initiated by the output endpoint and channel must be a connected output. The disconnect call is only forwarded to the opposite side of the channel element after the last input/output element on either side has been removed.

The ChannelElementBase implementation ignores the given channel and disconnects unconditinally.
