◆ field_cast()

template<typename TFieldTo , typename TFieldFrom >

TFieldTo comms::field_cast ( const TFieldFrom & field )

Cast between fields.

Sometimes the protocol may treat some specific field differently based on indication bit in some other field. This function can be used to cast one field to another type.

SomeFieldType someField = comms::field_cast<SomeFieldType>(someOtherField);

The function will perform some compile time analysis and will do a simple static_cast between the contained values if they are convertible. Otherwise the write + read operations will be performed, i.e. the source field will be written into a temporary buffer, and the target field will perform a read operation from that buffer.

Template Parameters

TFieldTo	Type to cast to.
TFieldFrom	Type to cast from.

Parameters

[in] field Original field

Returns: Field of the new type with internal value equivalent to one of the original field.

Note: Defined in "comms/cast.h" headerfile

		TFrame &&	frame,
		THandler &	handler
	)

Process all available input and dispatch all created message objects to appropriate handling function.

All the created message objects are immediatelly destructed after dispatching.

Parameters

[in,out]	bufIter	Iterator to input buffer. Passed by value and is NOT updated when buffer is iterated over (unlike comms::processSingle(), comms::processSingleWithDispatch(), comms::processSingleWithDispatchViaDispatcher()).
[in]	len	Number of remaining bytes in input buffer.
[in]	frame	Protocol frame / stack (see Transport Framing) that is used to process the raw input.
[in]	handler	Handler to handle message object when dispatched. The dispatch is performed using comms::dispatchMsg() function.

Returns: Number of consumed bytes from the buffer. The caller is responsible to remove them from the buffer.

Note: Defined in comms/process.h; If default dispatch behaviour of the comms::dispatchMsg() function doesn't suit the application needs, consider using comms::processAllWithDispatchViaDispatcher() instead.

[in]	len	Number of remaining bytes in input buffer.
[in]	frame	Protocol frame / stack (see Transport Framing) that is used to process the raw input.
[in]	handler	Handler to handle message object when dispatched. The dispatch is performed via provded TDispatcher class (see comms::MsgDispatcher).

Returns: Number of consumed bytes from the buffer. The caller is responsible to remove them from the buffer.
