Public Member Functions
virtual	~DtEnumLoader ()

virtual bool	loadFromDirectory (const DtFilename &directory, DtEnumDictionary &dict)

Add Interest in Enumerations
These methods can be used to tell the loader to read in enumerations that it does not support by default use standard formats.

virtual void	addInterestInEnumRange (DtEnumUid lowerUid, DtEnumUid upperUid)

virtual void	addInterestInEntityTypeEnum (DtEnumUid uid, DtEntityTypeField)

Registration/unregistration of Enumeration Reader Functions
These methods allow you to define custom functions for reading new file types or customizing how specific xml entries should be processed. Generally they are not needed by most users. If you wish the DtEnumLoader to read enumerations using existing functions for uids not read in by default, use #addInterestInEnumeration, addInterestInEnumRange, or addInterestInEntityTypeEnum.

Member Typedef Documentation

typedef DtEnumLoader*(* DtEnumLoader::EnumLoaderCreator)()

Type for the creator function for this class. See setCreator.

typedef std::list<DtEntityTypeRange> DtEnumLoader::Applicability

Type for specifying the applicability of an enumeration. This indicates what higher level entity type fields a given enumeration can be used with. DtEntityTypeRange supports a range of values within a given level, but you may need multiple different ranges, hence the list.

typedef boost::function<bool(const DtFilename&, DtEnumDictionary&)> DtEnumLoader::FileLoaderFcn

The function prototype for loading an enumerations file.

typedef boost::function<unsigned(const DtFilename&)> DtEnumLoader::FilePriorityReaderFcn

The function prototype for loading an enumerations file.

typedef boost::function<void(xmlNodePtr, const Applicability&, DtEnumDictionary&)> DtEnumLoader::XmlEntityTypeEntryReaderFcn

The function prototype for loading an individual entity type from an xml node.

typedef boost::function<void(xmlNodePtr, DtEnumDictionary&)> DtEnumLoader::XmlEntryReaderFcn

The function prototype for loading a individual enumeration from an xml node.

Constructor & Destructor Documentation

virtual DtEnumLoader::~DtEnumLoader ( )

virtual

Destructor.

DtEnumLoader::DtEnumLoader ( )

protected

Constructor is protected. Should call create() to create your loader. Ensures the registered creator function is called.

Member Function Documentation

static DtEnumLoader* DtEnumLoader::create ( )

static

Creates a new DtEnumLoader using the registered creator function.

static void DtEnumLoader::setCreator ( EnumLoaderCreator creator )

static

Sets the creator function used by create(). Use this to override what DtEnumLoader is created by the application. This is how a user would register their own subclass that might add functions for reading new all new file types or for specific enumerations.

virtual bool DtEnumLoader::loadFromDirectory	(	const DtFilename &	directory,
		DtEnumDictionary &	dict
	)

virtual

Loads all enumeration files from the given directory into the dictionary. Returns true if successful.

virtual void DtEnumLoader::addInterestInEnum ( DtEnumUid uid )

virtual

Adds interest in a general enumeration.

virtual void DtEnumLoader::addInterestInEnumRange	(	DtEnumUid	lowerUid,
		DtEnumUid	upperUid
	)

virtual

Adds interest in a range of general enumerations.

virtual void DtEnumLoader::addInterestInEntityTypeEnum	(	DtEnumUid	uid,
		DtEntityTypeField
	)

virtual

Adds interest in an entity type enumeration.

virtual void DtEnumLoader::registerFileLoader	(	const DtString &	fileExt,
		FileLoaderFcn	fcn
	)

virtual

Registers a function to load a specific file type.

virtual void DtEnumLoader::unregisterFileLoader ( const DtString & fileExt )

virtual

Remove a registered file loader.

virtual void DtEnumLoader::registerFilePriorityReader	(	const DtString &	fileExt,
		FilePriorityReaderFcn	fcn

virtual

Registers a function to read the load priority from a file.

virtual void DtEnumLoader::unregisterFilePriorityReader ( const DtString & fileExt )

virtual

Remove a registered priority reader.

		DtEnumUid	upperUid,
		XmlEntryReaderFcn	fcn

Registers a reader function for enumerations with a uid within a range of uid values (exclusive of the upperId). This will be used only if there is no specific uid reader specified via registerUidEntryReader.

virtual void DtEnumLoader::unregisterUidRangeEntryReader	(	DtEnumUid	lowerUid,
		DtEnumUid	upperUid
	)

virtual

Remove a registered enumeration reader function that was defined by a range of uids.

virtual

Registers a reader function for an entity type enumeration with a specific uid.

virtual

Remove a registered entity type enumeration reader function.

	)

virtual

Registers a general reader function for an entity type enumeration for a specific field level (e.g kind, domain, etc.). This will be used only if there is no specific uid reader specified via registerEntityTypeUidEntryReader.

virtual void DtEnumLoader::unregisterEntityTypeFieldEntryReader ( DtEntityTypeField lvl )

virtual

Remove a registered entity type enumeration reader function that was defined by for a field level.

virtual void DtEnumLoader::registerDefaultLoaders ( )

protectedvirtual

Registers default loader and reader functions for processing enums files. If not previously called, will be called by loadFromFiles() before starting load. Can be overridden in a subclass to provide different or additional default loaders.

virtual bool DtEnumLoader::loadFromXml	(	const DtFilename &	fn,
		DtEnumDictionary &	dict
	)

protectedvirtual

Default function used to load an xml enumerations file, such as SISO-REF-010.xml or MAK-Enums.xml.

protectedvirtual

Default function used to read the priority from an xml enumerations file, such as MAK-Enums.xml. SISO-REF-010.xml is always priority 0 and is loaded first.
