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);. More...
 
virtual void NewDocument (const TCollection_ExtendedString &format, Handle< TDocStd_Document > &aDoc)
 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. More...
 
virtual void InitDocument (const Handle< TDocStd_Document > &aDoc) const
 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 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) { cout << "document " << insession << " is already in session" << endl; return 0; }. More...
 
PCDM_ReaderStatus Open (const TCollection_ExtendedString &path, Handle< TDocStd_Document > &aDoc)

Handle< CDM_DocumentRetrieve (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...
