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.
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.

Handle< CDM_Document > CDF_Application::Retrieve ( const TCollection_ExtendedString aFolder,

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:

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 wil be used. A link is kept with the database through an instance of CDM_MetaData

Handle< CDM_Document > CDF_Application::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.

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
