Detailed Description

DtSimCommand is an abstract base class from which commands can derive.

It manages the read/write capability; derived classes need only use and register read/writable data types for derived information.

Constructors are protected because no one should instantiate the base class, just derived versions.

DtSimCommand::DtSimCommand ( const DtString &  writeName, DtReaderWriterRegistry *  parentRegistry = 0  )

constructor If you have a command 'put' itself, the write name will preface the command.

virtual bool DtSimCommand::init ( )

virtual

Base class init does nothing, but this will be called by create, in case any other deriving class needs to do virtual allocation.

virtual const DtSimCommandMessageType& DtSimCommand::type ( ) const

pure virtual

Returns

An integer the kind of simulation command. Derived classes must implement this member function to return a unique string representing the type of simCommand. The set of standard simCommand types supplied with VR-Forces is in radioMsgsTypes.h.

Implemented in DtCreateObjectCommand, DtAbandonPlanCommand, DtRestartPlanCommand, DtChangeGlobalWeatherCommand, DtConsoleMessageCommand, DtDeleteObjectCommand, DtSetDataCommand, DtChangeHostilityCommand, DtChangeTimeOfDayCommand, DtTaskCommand, MySimCommand, DtIssuePlanCommand, and DtNoopCommand.

virtual DtSimCommand* DtSimCommand::clone ( const DtString &  name, DtReaderWriterRegistry *  parentRegistry = 0  ) const

pure virtual

Make a copy of this sim command.

Returns a newly allocated instance of a DtSimCommand. Override this member function to return a pointer to a newly allocated instance of the derived class.

Implemented in DtCreateObjectCommand, DtAbandonPlanCommand, DtRestartPlanCommand, DtChangeGlobalWeatherCommand, DtConsoleMessageCommand, DtDeleteObjectCommand, DtSetDataCommand, DtChangeHostilityCommand, DtChangeTimeOfDayCommand, DtTaskCommand, MySimCommand, DtIssuePlanCommand, and DtNoopCommand.

virtual DtSimCommand* DtSimCommand::clone ( ) const

virtual

Version of clone that preserves the existing name, and assigns a null parent registry.

virtual DtString DtSimCommand::stringRep ( ) const

pure virtual

Returns a human-readable string representation of the command.

This string representation is used to display information about the command in the plan editor and viewer. The type and parameters for the command are typically encoded in the string. The format of the string is up to you.

Implemented in DtChangeGlobalWeatherCommand, DtCreateObjectCommand, DtChangeTimeOfDayCommand, DtAbandonPlanCommand, DtRestartPlanCommand, DtChangeHostilityCommand, DtConsoleMessageCommand, DtIssuePlanCommand, DtDeleteObjectCommand, DtSetDataCommand, DtTaskCommand, MySimCommand, and DtNoopCommand.

virtual void DtSimCommand::putData ( FILE *  fp, int  indentLevel = 0  )

virtual

putData writes our type, which is provided by the virtual type accessor of the deriving class.

Reimplemented from DtReaderWriter.

Reimplemented in DtSetDataCommand, and DtTaskCommand.

virtual DtlObjPtr DtSimCommand::getData ( DtlObjPtr  args, const DtFilename &  searchPath, const DtVariableBindingsList &  variableBindings  )

virtual

getData is just used to get us past the type in the data stream, since it's not actually stored.

Reimplemented in DtSetDataCommand, and DtTaskCommand.

virtual char* DtSimCommand::netRep ( )

virtual

virtual int DtSimCommand::netRepSize ( ) const

virtual

Returns the size in bytes of the network representation of the class.

This is the size in bytes of the DtNetSimSimCommand structure. Derived classes should take into acount the size returned by this class when overriding (they should call down to this class and add the result to their additional size).

Reimplemented in DtCreateObjectCommand, DtChangeHostilityCommand, DtConsoleMessageCommand, DtDeleteObjectCommand, DtSetDataCommand, DtTaskCommand, DtAbandonPlanCommand, DtRestartPlanCommand, DtIssuePlanCommand, MySimCommand, DtChangeGlobalWeatherCommand, DtChangeTimeOfDayCommand, and DtNoopCommand.

virtual bool DtSimCommand::setFromNet ( const char *  contentBuffer, unsigned  contentSize  )

virtual

Sets mySubsimCommand member from the incoming contentBuffer (cast to type DtNetSimSimCommand).

Derived classes should call down to this function first, and then extract their own data starting at the location contentBuffer + DtSimCommand::netRepSize().

Reimplemented in DtCreateObjectCommand, DtChangeHostilityCommand, DtConsoleMessageCommand, DtDeleteObjectCommand, DtSetDataCommand, DtTaskCommand, DtAbandonPlanCommand, DtRestartPlanCommand, MySimCommand, DtIssuePlanCommand, DtChangeGlobalWeatherCommand, DtNoopCommand, and DtChangeTimeOfDayCommand.

virtual bool DtSimCommand::setToNet ( )

virtual

Calls netRep() to create the network buffer.

Casts the resulting myNetRep to type DtNetSimSimCommand*, and then sets the mySubsimCommand member in the DtNetSimSimCommand from mySubsimCommand. Derived classes should call down to the base class version of setToNet() at the start of the function (before doing any processing on the network representation) They can then start to fill in their network data, starting at the location myNetRep + DtSimCommand::netRepSize().

Reimplemented in DtCreateObjectCommand, DtChangeHostilityCommand, DtConsoleMessageCommand, DtDeleteObjectCommand, DtSetDataCommand, DtTaskCommand, DtAbandonPlanCommand, DtRestartPlanCommand, MySimCommand, DtIssuePlanCommand, DtChangeGlobalWeatherCommand, DtNoopCommand, and DtChangeTimeOfDayCommand.

static DtSimCommand* DtSimCommand::createSimCommand ( DtlObjPtr  mtlStream )

static

Static functions.

Creates a new simCommand, given a pointer to a MAK Technologies LISP (MTL) stream. It first parses the stream to extract the type of simCommand to create. Then it calls the simCommand factory's create() member function with the given simCommand type. This returns a new instance of the particular simCommand type. The simCommand's getData() member function is then called to retrieve the simCommand parameters from the stream. The pointer to the new simCommand is returned.

static DtSimCommand* DtSimCommand::createSimCommand ( const DtSimCommandMessageType &  simCommandType )

static

static void DtSimCommand::addSimCommandCreatorFcn ( const DtSimCommandMessageType &  simCommandName, DtSimCommandCreatorFcn  fcn  )

static

Adds a simCommand creator member function to the simCommand factory.

static void DtSimCommand::setFactory ( DtSimCommandFactory *  factory )

static

static DtSimCommandFactory* DtSimCommand::factory ( )

static

Returns

A pointer to the static DtReaderWriterFactory. This factory can create instances of DtReaderWriter subclasses that have been registered with it.

Reimplemented from DtReaderWriter.
