DefineFormat()
  • Sets up resources and registers read and storage drivers for the specified format. @param theFormat - unique name for the format, used to identify it. @param theDescription - textual description of the format. @param theExtension - extension of the files in that format. The same extension can be used by several formats. @param theReader - instance of the read driver for the format. Null value is allowed (no possibility to read). @param theWriter - instance of the write driver for the format. Null value is allowed (no possibility to write).

GetDocument()
  • 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 opencascade::handle<TDocStd_Application> anApp; if (!CafTest::Find(A)) return 1; opencascade::handle<TDocStd> aDoc; Standard_Integer nbdoc = anApp->NbDocuments(); for (Standard_Integer i = 1; i <= nbdoc; i++) { aApp->GetDocument(i,aDoc);

IsDriverLoaded()

    rtype

    bool

IsInSession()
  • 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; }

ResourcesName()
  • Returns the name of the file containing the resources of this application, for support of legacy method of loading formats data from resource files. //! Method DefineFormat() can be used to define all necessary parameters explicitly without actually using resource files. //! In a resource file, the application associates the schema name of the document with the storage and retrieval plug-ins that are to be loaded for each document. On retrieval, the application reads the schema name in the heading of the CSF file and loads the plug-in indicated in the resource file. This plug-in instantiates the actual driver for transient-persistent conversion. Your application can bring this process into play by defining a class which inherits CDF_Application and redefines the function which returns the appropriate resources file. At this point, the function Retrieve and the class CDF_Store can be called. This allows you to deal with storage and retrieval of - as well as copying and pasting - documents. To implement a class like this, several virtual functions should be redefined. In particular, you must redefine the abstract function Resources inherited from the superclass CDM_Application. //! Default implementation returns empty string.
