Public Member Functions inherited from TDocStd_Application
	TDocStd_Application ()

virtual Handle< Message_Messenger >	MessageDriver () override
	Redefines message driver, by default outputs to std::cout. More...

virtual Handle< Resource_Manager >	Resources () override
	Returns resource manager defining supported persistent formats. More...

void	DefineFormat (const TCollection_AsciiString &theFormat, const TCollection_AsciiString &theDescription, const TCollection_AsciiString &theExtension, const Handle< PCDM_RetrievalDriver > &theReader, const Handle< PCDM_StorageDriver > &theWriter)

	Returns the sequence of reading formats supported by the application. More...

void	WritingFormats (TColStd_SequenceOfAsciiString &theFormats)
	Returns the sequence of writing formats supported by the application. More...

Standard_Integer	NbDocuments () const
	returns the number of documents handled by the current applicative session. More...

void	GetDocument (const Standard_Integer index, Handle< TDocStd_Document > &aDoc) const
	Constructs the new document aDoc. aDoc is identified by the index index which is any integer between 1 and n where n is the number of documents returned by NbDocument. Example Handle(TDocStd_Application) anApp; if (!CafTest::Find(A)) return 1; Handle(TDocStd) aDoc; Standard_Integer nbdoc = anApp->NbDocuments(); for (Standard_Integer i = 1; i <= nbdoc; i++) { aApp->GetDocument(i,aDoc);.

virtual void	NewDocument (const TCollection_ExtendedString &format, Handle< TDocStd_Document > &aDoc)

	Close the given document. the document is not any more handled by the applicative session. More...

Standard_Integer	IsInSession (const TCollection_ExtendedString &path) const
	Returns an index for the document found in the path path in this applicative session. If the returned value is 0, the document is not present in the applicative session. This method can be used for the interactive part of an application. For instance, on a call to Open, the document to be opened may already be in memory. IsInSession checks to see if this is the case. Open can be made to depend on the value of the index returned: if IsInSession returns 0, the document is opened; if it returns another value, a message is displayed asking the user if he wants to override the version of the document in memory. Example: Standard_Integer insession = A->IsInSession(aDoc); if (insession > 0) { std::cout << "document " << insession << " is already in session" << std::endl; return 0; }. More...

PCDM_ReaderStatus	Open (const TCollection_ExtendedString &path, Handle< TDocStd_Document > &aDoc)
	Retrieves the document aDoc stored under the name aName in the directory directory. In order not to override a version of aDoc which is already in memory, this method can be made to depend on the value returned by IsInSession. More...

	Save the active document in the file <name> in the path <path> . overwrite the file if it already exist. More...

PCDM_StoreStatus	SaveAs (const Handle< TDocStd_Document > &theDoc, Standard_OStream &theOStream, TCollection_ExtendedString &theStatusMessage)

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

Handle< CDM_Document >	Retrieve (const TCollection_ExtendedString &aFolder, const TCollection_ExtendedString &aName, const Standard_Boolean UseStorageConfiguration=Standard_True)
	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: More...

Handle< CDM_Document >	Retrieve (const TCollection_ExtendedString &aFolder, const TCollection_ExtendedString &aName, const TCollection_ExtendedString &aVersion, const Standard_Boolean UseStorageConfiguration=Standard_True)
	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. More...
