Member Function Documentation

◆ CanClose()

◆ CanRetrieve() [1/2]

		const TCollection_ExtendedString &	theName,
		const TCollection_ExtendedString &	theVersion,
		const bool	theAppendMode
	)

◆ Close()

void CDF_Application::Close ( const Handle< CDM_Document > & aDocument )

removes the document of the current session directory and closes the document;

◆ DefaultFolder()

Standard_ExtString CDF_Application::DefaultFolder ( )

◆ Format()

Standard_Boolean CDF_Application::Format	(	const TCollection_ExtendedString &	aFileName,
		TCollection_ExtendedString &	theFormat
	)

try to retrieve a Format directly in the file or in application resource by using extension. returns True if found;

◆ GetRetrieveStatus()

PCDM_ReaderStatus CDF_Application::GetRetrieveStatus ( ) const

inline

Checks status after Retrieve.

◆ InitDocument()

virtual void CDF_Application::InitDocument ( const Handle< CDM_Document > & theDoc ) const

virtual

Initialize a document for the applicative session. This virtual function is called by NewDocument and should be redefined for each specific application.

Reimplemented in TDocStd_Application, and XCAFApp_Application.

◆ Load()

static Handle< CDF_Application > CDF_Application::Load ( const Standard_GUID & aGUID )

static

plugs an application.

Open is used

for opening a Document that has been created in an application
for opening a Document from the database
for opening a Document from a file. The Open methods always add the document in the session directory and calls the virtual Activate method. The document is considered to be opened until Close is used. To be storable, a document must be opened by an application since the application resources are needed to store it.

◆ MetaDataDriver()

Handle< CDF_MetaDataDriver > CDF_Application::MetaDataDriver ( ) const

returns MetaDatdDriver of this application

◆ NewDocument()

virtual void CDF_Application::NewDocument	(	const TCollection_ExtendedString &	theFormat,
		Handle< CDM_Document > &	theDoc
	)

virtual

Constructs an new empty document. This document will have the specified format. If InitDocument() is redefined for a specific application, the new document is handled by the applicative session.

Reimplemented in TDocStd_Application.

◆ Open()

void CDF_Application::Open ( const Handle< CDM_Document > & aDocument )

puts the document in the current session directory and calls the virtual method Activate on it.

◆ Read()

void CDF_Application::Read	(	Standard_IStream &	theIStream,
		Handle< CDM_Document > &	theDocument,
		const Handle< PCDM_ReaderFilter > &	theFilter = `Handle< PCDM_ReaderFilter >()`,
		const Message_ProgressRange &	theRange = `Message_ProgressRange()`
	)

Reads theDocument from standard SEEKABLE stream theIStream, the stream should support SEEK functionality.

◆ ReaderFromFormat()

virtual Handle< PCDM_Reader > CDF_Application::ReaderFromFormat ( const TCollection_ExtendedString & aFormat )

virtual

Returns instance of read driver for specified format.

Default implementation uses plugin mechanism to load reader dynamically. For this to work, application resources should define GUID of the plugin as value of [Format].RetrievalPlugin, and "Plugin" resource should define name of plugin library to be loaded as value of [GUID].Location. Plugin library should provide method PLUGINFACTORY returning instance of the reader for the same GUID (see Plugin_Macro.hxx).

In case if reader is not available, will raise Standard_NoSuchObject or other exception if raised by plugin loader.

◆ Retrieve() [1/2]

Handle< CDM_Document > CDF_Application::Retrieve	(	const TCollection_ExtendedString &	aFolder,
		const TCollection_ExtendedString &	aName,
		const Standard_Boolean	UseStorageConfiguration = `Standard_True`,
		const Handle< PCDM_ReaderFilter > &	theFilter = `Handle< PCDM_ReaderFilter >()`,
		const Message_ProgressRange &	theRange = `Message_ProgressRange()`
	)

This method retrieves a document from the database. If the Document references other documents which have been updated, the latest version of these documents will be used if {UseStorageConfiguration} is Standard_True. The content of {aFolder}, {aName} and {aVersion} depends on the Database Manager system. If the DBMS is only based on the OS, {aFolder} is a directory and {aName} is the name of a file. In this case the use of the syntax with {aVersion} has no sense. For example:

Handle(CDM_Document) theDocument=myApplication->Retrieve("/home/cascade","box.dsg"); If the DBMS is EUCLID/Design Manager, {aFolder}, {aName} have the form they have in EUCLID/Design Manager. For example:

Handle(CDM_Document) theDocument=myApplication->Retrieve("|user|cascade","box");

Since the version is not specified in this syntax, the latest will be used. A link is kept with the database through an instance of CDM_MetaData

◆ Retrieve() [2/2]

Handle< CDM_Document > CDF_Application::Retrieve	(	const TCollection_ExtendedString &	aFolder,
		const TCollection_ExtendedString &	aName,
		const TCollection_ExtendedString &	aVersion,
		const Standard_Boolean	UseStorageConfiguration = `Standard_True`,
		const Handle< PCDM_ReaderFilter > &	theFilter = `Handle< PCDM_ReaderFilter >()`,
		const Message_ProgressRange &	theRange = `Message_ProgressRange()`
	)

This method retrieves a document from the database. If the Document references other documents which have been updated, the latest version of these documents will be used if {UseStorageConfiguration} is Standard_True. – If the DBMS is only based on the OS, this syntax should not be used.

If the DBMS is EUCLID/Design Manager, {aFolder}, {aName} and {aVersion} have the form they have in EUCLID/Design Manager. For example:

Handle(CDM_Document) theDocument=myApplication->Retrieve("|user|cascade","box","2"); A link is kept with the database through an instance of CDM_MetaData

◆ SetDefaultFolder()

Standard_Boolean CDF_Application::SetDefaultFolder ( const Standard_ExtString aFolder )

◆ WriterFromFormat()

virtual Handle< PCDM_StorageDriver > CDF_Application::WriterFromFormat ( const TCollection_ExtendedString & aFormat )

virtual

Returns instance of storage driver for specified format.

Default implementation uses plugin mechanism to load driver dynamically. For this to work, application resources should define GUID of the plugin as value of [Format].StoragePlugin, and "Plugin" resource should define name of plugin library to be loaded as value of [GUID].Location. Plugin library should provide method PLUGINFACTORY returning instance of the reader for the same GUID (see Plugin_Macro.hxx).

In case if driver is not available, will raise Standard_NoSuchObject or other exception if raised by plugin loader.
