virtual void* RTT::types::TypeMarshaller::createCookie ( ) const

inlinevirtualinherited

Overload in subclasses for marshallers that need to allocate some internal data.

The protocol will call deleteCookie(void*) accordingly

virtual base::ChannelElementBase::shared_ptr RTT::mqueue::MQTemplateProtocolBase< T >::createStream	(	base::PortInterface *	port,
		const ConnPolicy &	policy,
		bool	is_sender
	)		const

inlinevirtualinherited

Creates a streaming channel element for reading or writing over this transport.

It returns a ChannelElementBase that provides the implementation of sending or receiving data through the transport. Both sender and receiver find each other using the channel_id argument. Transports that do not support streaming may return null

Parameters

port	The port for which this channel is setup.
channel_id	If the transport receives a non-empty channel_id, it will create a channel that connects to this id. If channel id is empty, it will be filled in with a unique identifier that identifies this channel. This allows the local caller to connect to the remote channel in a second invocation of createRemoteChannel.
is_sender	Set to true in case you will write() to this channel element, set it to false in case you will read() from this channel element.

Returns: null in case streaming is not supported by this transport or a valid channel element otherwise.

Implements RTT::types::TypeTransporter.

		void *	blob,
		int	size,
		void *	cookie
	)		const

inlinevirtual

Create an transportable object for a protocol which contains the value of source.

This must be a real-time function which does not allocate memory

Parameters

source	The data to be read
blob	Suggested target memory area to write to. In case the type marshaller does not need this, it will return an alternative as a first element in the returned std::pair.
size	The size of the memory area pointed by blob

Returns: Returns (0,0) if the filling failed, otherwise, points to the filled memory area and the effectively written size. The returned pointer may differ from blob, in case blob was not used. The returned size must be lower or equal than size
