Inheritance diagram for AppStdL_Application:

Public Member Functions
const char *	ResourcesName () override
	returns the file name which contains application resources
void	DumpJson (Standard_OStream &theOStream, int theDepth=-1) const
	Dumps the content of me into the stream.
Public Member Functions inherited from TDocStd_Application
	TDocStd_Application ()
	Constructs the new instance and registers it in CDM_Session.
bool	IsDriverLoaded () const
	Check if meta data driver was successfully loaded by the application constructor.
occ::handle< Resource_Manager >	Resources () override
	Returns resource manager defining supported persistent formats.
void	DefineFormat (const TCollection_AsciiString &theFormat, const TCollection_AsciiString &theDescription, const TCollection_AsciiString &theExtension, const occ::handle< PCDM_RetrievalDriver > &theReader, const occ::handle< PCDM_StorageDriver > &theWriter)
	Sets up resources and registers read and storage drivers for the specified format.
void	ReadingFormats (NCollection_Sequence< TCollection_AsciiString > &theFormats)
	Returns the sequence of reading formats supported by the application.
void	WritingFormats (NCollection_Sequence< TCollection_AsciiString > &theFormats)
	Returns the sequence of writing formats supported by the application.
int	NbDocuments () const
	returns the number of documents handled by the current applicative session.
occ::handle< TDocStd_Document >	GetDocument (const int indexindex) const
	Returns the document at the given 1-based index. The index is any integer between 1 and NbDocuments().
void	GetDocument (const int indexindex, occ::handle< TDocStd_Document > &aDoc) const
void	NewDocument (const TCollection_ExtendedString &formatformat, occ::handle< CDM_Document > &aDoc) override
	Constructs the empty new document aDoc. This document will have the format format. If InitDocument is redefined for a specific application, the new document is handled by the applicative session.
void	NewDocument (const TCollection_ExtendedString &formatformat, occ::handle< TDocStd_Document > &aDoc)
	A non-virtual method taking a TDocStd_Documment object as an input. Internally it calls a virtual method NewDocument() with CDM_Document object.
void	InitDocument (const occ::handle< CDM_Document > &aDoc) const override
	Initialize the document aDoc for the applicative session. This virtual function is called by NewDocument and is to be redefined for each specific application.
void	Close (const occ::handle< TDocStd_Document > &aDoc)
	Close the given document. the document is not any more handled by the applicative session.
int	IsInSession (const TCollection_ExtendedString &pathpath) 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: int insession = A->IsInSession(aDoc); if (insession > 0) { std::cout << "document " << insession << " is already in session" << std::endl; return 0; }.
PCDM_ReaderStatus	Open (const TCollection_ExtendedString &thePath, occ::handle< TDocStd_Document > &theDoc, const occ::handle< PCDM_ReaderFilter > &theFilter, const Message_ProgressRange &theRange=Message_ProgressRange())

	Retrieves the document from specified file. In order not to override a version of the document which is already in memory, this method can be made to depend on the value returned by IsInSession.
PCDM_ReaderStatus	Open (Standard_IStream &theIStream, occ::handle< TDocStd_Document > &theDoc, const occ::handle< PCDM_ReaderFilter > &theFilter, const Message_ProgressRange &theRange=Message_ProgressRange())
	Retrieves document from standard stream.

	Retrieves document from standard stream.
PCDM_StoreStatus	SaveAs (const occ::handle< TDocStd_Document > &theDoc, const TCollection_ExtendedString &pathpath, const Message_ProgressRange &theRange=Message_ProgressRange())
	Save the active document in the file <name> in the path <path>. overwrites the file if it already exists.
PCDM_StoreStatus	SaveAs (const occ::handle< TDocStd_Document > &theDoc, Standard_OStream &theOStream, const Message_ProgressRange &theRange=Message_ProgressRange())
	Save theDoc to standard SEEKABLE stream theOStream. the stream should support SEEK functionality.
PCDM_StoreStatus	Save (const occ::handle< TDocStd_Document > &theDoc, const Message_ProgressRange &theRange=Message_ProgressRange())
	Save aDoc active document. Exceptions: Standard_NotImplemented if the document was not retrieved in the applicative session by using Open.
PCDM_StoreStatus	SaveAs (const occ::handle< TDocStd_Document > &theDoc, const TCollection_ExtendedString &pathpath, TCollection_ExtendedString &theStatusMessage, const Message_ProgressRange &theRange=Message_ProgressRange())

PCDM_StoreStatus	SaveAs (const occ::handle< TDocStd_Document > &theDoc, Standard_OStream &theOStream, TCollection_ExtendedString &theStatusMessage, const Message_ProgressRange &theRange=Message_ProgressRange())
	Save theDoc TO standard SEEKABLE stream theOStream. the stream should support SEEK functionality.
PCDM_StoreStatus	Save (const occ::handle< TDocStd_Document > &theDoc, TCollection_ExtendedString &theStatusMessage, const Message_ProgressRange &theRange=Message_ProgressRange())
	Save the document overwriting the previous file.
virtual void	OnOpenTransaction (const occ::handle< TDocStd_Document > &theDoc)
	Notification that is fired at each OpenTransaction event.

Public Member Functions inherited from CDF_Application
void	Open (const occ::handle< CDM_Document > &aDocument)
	puts the document in the current session directory and calls the virtual method Activate on it.
CDM_CanCloseStatus	CanClose (const occ::handle< CDM_Document > &aDocument)
void	Close (const occ::handle< CDM_Document > &aDocument)
	removes the document of the current session directory and closes the document;
occ::handle< CDM_Document >	Retrieve (const TCollection_ExtendedString &aFolder, const TCollection_ExtendedString &aName, const bool UseStorageConfiguration=true, const occ::handle< PCDM_ReaderFilter > &theFilter=occ::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 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:
occ::handle< CDM_Document >	Retrieve (const TCollection_ExtendedString &aFolder, const TCollection_ExtendedString &aName, const TCollection_ExtendedString &aVersion, const bool UseStorageConfiguration=true, const occ::handle< PCDM_ReaderFilter > &theFilter=occ::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 true. If the DBMS is only based on the OS, this syntax should not be used.
PCDM_ReaderStatus	CanRetrieve (const TCollection_ExtendedString &theFolder, const TCollection_ExtendedString &theName, const bool theAppendMode)
PCDM_ReaderStatus	CanRetrieve (const TCollection_ExtendedString &theFolder, const TCollection_ExtendedString &theName, const TCollection_ExtendedString &theVersion, const bool theAppendMode)
PCDM_ReaderStatus	GetRetrieveStatus () const
	Checks status after Retrieve.
void	Read (Standard_IStream &theIStream, occ::handle< CDM_Document > &theDocument, const occ::handle< PCDM_ReaderFilter > &theFilter=occ::handle< PCDM_ReaderFilter >(), const Message_ProgressRange &theRange=Message_ProgressRange())

	Empty constructor.
	Standard_Transient (const Standard_Transient &)
	Copy constructor – does nothing.
Standard_Transient &	operator= (const Standard_Transient &)
	Assignment operator, needed to avoid copying reference counter.
virtual	~Standard_Transient ()=default
	Destructor must be virtual.
virtual const opencascade::handle< Standard_Type > &	DynamicType () const
	Returns a type descriptor about this object.
bool	IsInstance (const opencascade::handle< Standard_Type > &theType) const
	Returns a true value if this is an instance of Type.
bool	IsInstance (const char *const theTypeName) const
	Returns a true value if this is an instance of TypeName.
bool	IsKind (const opencascade::handle< Standard_Type > &theType) const
	Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
bool	IsKind (const char *const theTypeName) const
	Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
Standard_Transient *	This () const
	Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
int	GetRefCount () const noexcept
	Get the reference counter of this object.
void	IncrementRefCounter () noexcept
	Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
int	DecrementRefCounter () noexcept
	Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
virtual void	Delete () const
	Memory deallocator for transient classes.
