makRadarFx::DtVreMessageFactory Class Reference

Detailed Description

This class manages the creation of message objects from encoded byte arrays. It maintains a registry of message types and their corresponding decoder functions, allowing the system to dynamically create the appropriate message object based on the message type found in the encoded data.

Member Typedef Documentation

DecoderMap

typedef std::map<unsigned int, Decoder> makRadarFx::DtVreMessageFactory::DecoderMap

protected

Type definition for the map of message types to decoder functions.

Constructor & Destructor Documentation

DtVreMessageFactory()

makRadarFx::DtVreMessageFactory::DtVreMessageFactory	(	bool	initializeDefaults = true,
		bool	isBigEndian = false )

Constructor with initialization options.

Parameters

initializeDefaults	Whether to automatically register default message decoders
isBigEndian	Whether the encoded data is in big-endian format

Creates a new message factory. If initializeDefaults is true, the factory will be automatically populated with decoders for all standard RadarFX messages.

~DtVreMessageFactory()

virtual makRadarFx::DtVreMessageFactory::~DtVreMessageFactory ( )

virtual

Virtual destructor.

Cleans up factory resources

Member Function Documentation

create() [1/2]

virtual DtBaseMessage * makRadarFx::DtVreMessageFactory::create ( unsigned char * bytes, int length )

virtual

Creates a message from encoded bytes.

Parameters

bytes	Pointer to the encoded byte array
length	Length of the encoded byte array

Returns

Pointer to the newly created message instance, or nullptr on error

Decodes the message type from the byte array and creates the appropriate message object. Returns nullptr if there is no decoder registered for the message type or if decoding fails.

create() [2/2]

virtual DtBaseMessage * makRadarFx::DtVreMessageFactory::create ( int msgType, unsigned char * bytes, int length )

virtual

Creates a message from encoded bytes with known message type.

Parameters

msgType	The type of message to create
bytes	Pointer to the encoded byte array
length	Length of the encoded byte array

Returns

Pointer to the newly created message instance, or nullptr on error

Creates a message object for the specified message type. Returns nullptr if there is no decoder registered for the message type or if decoding fails.

registerCreator()

virtual void makRadarFx::DtVreMessageFactory::registerCreator ( unsigned int type, Decoder decoder )

virtual

Registers a message decoder function.

Parameters

type	Message type identifier
decoder	Function pointer to the decoder function

Associates a message decoder function with a specific message type. The decoder will be used to create message objects of that type when decoding encoded data.

initializeDefaultMessages()

virtual void makRadarFx::DtVreMessageFactory::initializeDefaultMessages ( )

virtual

Initializes the factory with decoders for standard message types.

Registers decoder functions for all the standard RadarFX message types. This is automatically called by the constructor if initializeDefaults is true.

clear()

virtual void makRadarFx::DtVreMessageFactory::clear ( )

virtual

Clears all registered decoders.

Removes all decoder registrations from the factory, effectively resetting it to an empty state.

Member Data Documentation

myCreatorMap

DecoderMap makRadarFx::DtVreMessageFactory::myCreatorMap

protected

Map of message types to their corresponding decoder functions.

myIsBigEndian

bool makRadarFx::DtVreMessageFactory::myIsBigEndian

protected

Flag indicating if the encoded data is in big-endian format.
