|

| virtual Standard_CString | ResourcesName ()=0 |
| | Returns the name of the file containing the resources of this application. 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. 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) { cout << "document " << insession << " is already in session" << endl; return 0; }. 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...

The abstract root class for all application classes. They are in charge of:
- Creating documents
- Storing documents and retrieving them
- Initializing document views. To create a useful OCAF-based application, you derive a class from Application and implement the methods below. You will have to redefine the deferred (virtual) methods Formats, InitDocument, and Resources, and override others. The application is a container for a document, which in its turn is the container of the data framework made up of labels and attributes. Besides furnishing a container for documents, TDocStd_Application provides the following services for them:
- Creation of new documents
- Activation of documents in sessions of an application
- Storage and retrieval of documents
- Initialization of document views. Note: If a client needs detailed information concerning the events during the Open/Store operation, MessageDriver inherited from CDM_MessageDriver of the corresponding application has to be implemented. If the MessageDriver is not defined all messages will be (by default) directed to CDM_NullMessageDriver and will be lost.
