Detailed Description

Instances of DtFomMapper are used to provide FOM agility in VR-Link by mapping VR-Link classes and functionality to FOM classes, attributes and parameters.

DtFomMapper is an abstract class. Most FOM Mappers (including DtRprFomMapper) are derived from DtEmptyFomMapper, and not directly from DtFomMapper.

Member Typedef Documentation

typedef char*(* DtFomMapper::DtInteractionClassChooser)(DtExerciseConn *exConn, const DtInteraction &inter)

A function that chooses an interaction class from the FOM based on the contents of a derived DtInteraction object.

typedef char*(* DtFomMapper::DtInteractionClassChooserWithUsrData)(DtExerciseConn *exConn, const DtInteraction &inter, void *usr)

Same as DtInteractionClassChooser but allows a user to specify a void* to be passed as user data.

The user data pointer is specified when the class chooser is registered.

typedef char*(* DtFomMapper::DtObjectClassChooser)(const char *vrlinkClassName, DtExerciseConn *conn, void *fomClassSpecific)

A function that chooses an object class from the FOM based based on the name of a C++ class derived from DtObjectPublisher and FOM class specific data deemed relevant by the publisher class (e.g.

entity type).

typedef char*(* DtFomMapper::DtObjectClassChooserWithUsrData)(const char *vrlinkClassName, DtExerciseConn *conn, void *fomClassSpecific, void *usr)

Same as DtObjectClassChooser but allows a user to specify a void* to be passed as user data.

The user data pointer is specified when the class chooser is registered.

		const char *	objClassName,
		bool	includeSubclasses
	)

virtual

If includeSubclasses is set to true, this function will recurse through all child FOM classes of that type.

virtual void DtFomMapper::addObjectClassName	(	const char *	vrlinkClassName,
		const char *	objClassName,
		bool	includeSubclasses
	)

virtual

Modify the list of names of FOM objects that should be subscribed to by a particular subclass of VR-Link.

If includeSubclasses is set to true, this function will recurse through all child FOM classes of that type.

virtual const char* DtFomMapper::chooseInteractionClass ( const DtInteraction & inter ) const

virtual

Chooses a FOM interaction class to be by a particular derived DtInteraction class named vrlinkClassName.

virtual const char* DtFomMapper::chooseObjectClass	(	const char *	vrlinkClassName,
		void *	fomClassSpecific = `NULL`
	)		const

virtual

Chooses an object class to represent an object managed by the C++ class named vrlinkClassName (which should be a class derived from DtObjectPublisher).

fomClassSpecific is additional data deemed relevant to make the choice by the publisher class (e.g. entity type). It is passed as fomClassSpecific to a chooser function that has been registered with the FOM Mapper for this publisher type, if any.

virtual DtHlaObjectFactory* DtFomMapper::hlaObjectFactory ( )

virtual

virtual void DtFomMapper::init ( DtExerciseConn * conn )

pure virtual

Initialize the instance, once an exercise connection is available.

Must be overridden in subclasses.

Implemented in DtRprFomMapper, MyFomMapper, and DtEmptyFomMapper.

virtual DtList* DtFomMapper::objectClassHandles ( const char * vrlinkClassName )

virtual

Similar to objectClassNames, but returns a DtList of ObjectClassHandles instead.

The returned list is owned by the DtFomMapper, and should not be deleted. In addition, it is only valid until the next call to this function. If using HLA 1.3 the ObjectClassHandles are returned cast as void * in the list If using HLA 1516 the list contains pointers to a valid RTI::ObjectClassHandle

virtual const std::vector<DtString>* DtFomMapper::objectClassNames ( const char * vrlinkClassName )

virtual

DtFomMapper& DtFomMapper::operator= ( const DtFomMapper & orig )

protected

assignment operator - not implemented.

	)

virtual

virtual void DtFomMapper::removeObjectClassName	(	const char *	vrlinkClassName,
		const char *	objClassName,
		bool	includeSubclasses
	)

virtual

virtual int DtFomMapper::revision ( ) const

virtual

Returns the revision number of the FOM.

A revision is defined as a particular way that the FOM Mapper translates a specific FOM. In general, it increases when we there is a bug in translation that cannot be fixed without breaking backwards compatibility. For this reason, it is recommended that one uses the latest revision number available for your specific FOM.

virtual DtHlaObjectFactory* DtFomMapper::setHlaObjectFactory ( DtHlaObjectFactory * fact )

virtual

Set/Get the current factory that can be used to create DtHlaObjects.

virtual void DtFomMapper::setInteractionClass	(	const char *	vrlinkClassName,
		const char *	fomClassName
	)

virtual

When there is only a single FOM class to be associated with a VR-Link interaction class, then there is no need to create a DtList.

Just use this:

virtual void DtFomMapper::setInteractionClassChooser	(	const char *	vrlinkClassName,
		DtInteractionClassChooser	chooser
	)

virtual

virtual void DtFomMapper::setInteractionClassChooser	(	const char *	vrlinkClassName,
		DtInteractionClassChooserWithUsrData	chooser,
		void *	usr
	)

virtual

virtual void DtFomMapper::setInteractionClasses	(	const char *	vrlinkClassName,
		const std::vector< DtString > &	classes
	)

virtual

Set/Get a list of names (char*) of FOM classes that can be decoded into the derived DtInteraction class whose name is name.

These classes will be subscribed to, when you use a derived DtInteraction's addCallback function. The DtFomMapper copies the data in the list passed to setInteractionClasses, so the object can be deleted at the caller's leisure. The list returned by interactionClasses is owned by the DtFomMapper and shouldn't be deleted by the caller.

virtual void DtFomMapper::setInteractionClassToChoose	(	const char *	vrlinkClassName,
		const char *	fomClassName
	)

virtual

Tell the FOM Mapper how to choose a FOM interaction class to use for a particular kind of derived DtInteraction.

You can either associate a single FOM class name, or a FOM class choosing function with the name of a C++ class derived from DtInteraction.

virtual DtInteractionDecoderFactory* DtFomMapper::setInteractionDecoderFactory ( DtInteractionDecoderFactory * fact )

virtual

Set/Get the current factory that can be used to create DtInteractionDecoders.

virtual DtInteractionEncoderFactory* DtFomMapper::setInteractionEncoderFactory ( DtInteractionEncoderFactory * fact )

virtual

Set/Get the current factory that can be used to create DtInteractionEncoders.

virtual DtInteractionFactory* DtFomMapper::setInteractionFactory ( DtInteractionFactory * fact )

virtual

Set/Get the current factory that can be used to create DtInteractions.

virtual void DtFomMapper::setObjectClass	(	const char *	vrlinkClassName,
		const char *	fomClassName
	)

virtual

When there is only a single FOM class to be associated with a VR-Link DtReflectedObjectList class, then there is no need to create a DtList.

Just use this:

virtual void DtFomMapper::setObjectClassChooser	(	const char *	vrlinkClassName,
		DtObjectClassChooser	chooser
	)

virtual

virtual void DtFomMapper::setObjectClassChooser	(	const char *	vrlinkClassName,
		DtObjectClassChooserWithUsrData	chooser,
		void *	usr
	)

virtual

virtual void DtFomMapper::setObjectClassNames	(	const char *	vrlinkClassName,
		const std::vector< DtString > &	classes
	)

virtual

Set/Get a list of names (char*) of FOM object classes that should be subscribed to by a particular subclass of VR-Link's DtReflectedObjectList.

vrlinkClassName is the name of the DtReflectedObjectList subclass for which you are creating a mapping. The DtFomMapper copies the data in the list passed to setObjectClassNames, so the object can be deleted at the caller's leisure. The list returned by objectClassNames is owned by the DtFomMapper and shouldn't be deleted by the caller.

virtual void DtFomMapper::setObjectClassToChoose	(	const char *	vrlinkClassName,
		const char *	fomClassName
	)

virtual

Tell the FOM Mapper how to choose a FOM object class to use for objects being published by a particular kind of object publisher.

You can either associate a single FOM class name, or a FOM class choosing function with the name of a C++ class derived from DtObjectPublisher.

virtual void DtFomMapper::setRevision ( int val )

virtual

Sets the revision number of the FOM.

A revision is defined as a particular way that the FOM Mapper translates the FOM. In general, it increases when we there is a bug in translation that cannot be fixed without breaking backwards compatibility. For this reason, it is recommended that one uses the latest revision number available for your specific FOM.

virtual DtStateDecoderFactory* DtFomMapper::setStateDecoderFactory ( DtStateDecoderFactory * fact )

virtual

Set/Get the current factory that can be used to create DtHlaStateDecoders.

virtual DtStateEncoderFactory* DtFomMapper::setStateEncoderFactory ( DtStateEncoderFactory * fact )

virtual

Set/Get the current factory that can be used to create DtHlaStateEncoders.

virtual void DtFomMapper::setVersion ( double vers )

virtual

Returns the version number of the FOM, as passed to setVersion.

A Version is defined as a specific type of FOM file. For example, RPR Version 2.0 Draft 17 is defined as version 2.0017. This can be used jointly with the revision to define both what the FOM being read is as well as how to interpret it.
