Detailed Description
Class for synchronization of transactions within multiple documents. Each transaction of this class involvess one transaction in each modified document.
The documents to be synchronized should be added explicitly to the manager; then its interface is uesd to ensure that all transactions (Open/Commit, Undo/Redo) are performed synchronously in all managed documents.
The current implementation does not support nested transactions on multitransaction manager level. It only sets the flag enabling or disabling nested transactions in all its documents, so that a nested transaction can be opened for each particular document with TDocStd_Document class interface.
NOTE: When you invoke CommitTransaction of multi transaction manager, all nested transaction of its documents will be closed (commited).
Constructor & Destructor Documentation
◆ TDocStd_MultiTransactionManager()
| TDocStd_MultiTransactionManager::TDocStd_MultiTransactionManager | ( | ) |
Constructor.
Member Function Documentation
◆ AbortCommand()
| void TDocStd_MultiTransactionManager::AbortCommand | ( | ) |
Unsets the flag of started manager transaction and aborts transaction in each document.
◆ AddDocument()
| void TDocStd_MultiTransactionManager::AddDocument | ( | const Handle< TDocStd_Document > & | theDoc | ) |
Adds the document to the transaction manager and checks if it has been already added.

◆ CommitCommand() [1/2]
| Standard_Boolean TDocStd_MultiTransactionManager::CommitCommand | ( | ) |

◆ CommitCommand() [2/2]
| Standard_Boolean TDocStd_MultiTransactionManager::CommitCommand | ( | const TCollection_ExtendedString & | theName | ) |

Returns available manager undos.
◆ GetUndoLimit()
| Standard_Integer TDocStd_MultiTransactionManager::GetUndoLimit | ( | ) | const |
Returns undo limit for the manager.
◆ HasOpenCommand()
| Standard_Boolean TDocStd_MultiTransactionManager::HasOpenCommand | ( | ) | const |
Returns true if a transaction is opened.
◆ IsNestedTransactionMode()
| Standard_Boolean TDocStd_MultiTransactionManager::IsNestedTransactionMode | ( | ) | const |
Returns Standard_True if NestedTransaction mode is set. Methods for protection of changes outside transactions.
◆ ModificationMode()
| Standard_Boolean TDocStd_MultiTransactionManager::ModificationMode | ( | ) | const |
Returns True if changes are allowed only inside transactions.
◆ OpenCommand()
| void TDocStd_MultiTransactionManager::OpenCommand | ( | ) |
Opens transaction in each document and sets the flag that transaction is opened. If there are already opened transactions in the documents, these transactions will be aborted before openning new ones.
◆ Redo()
| void TDocStd_MultiTransactionManager::Redo | ( | ) |
Redoes the current transaction of the application. It calls the Redo () method of the document being on top of the manager list of redos (list.First()) and moves the list item to the top of the list of manager undos (list.Prepend(item)).
◆ RemoveDocument()
| void TDocStd_MultiTransactionManager::RemoveDocument | ( | const Handle< TDocStd_Document > & | theDoc | ) |
Removes the document from the transaction manager.
◆ RemoveLastUndo()
| void TDocStd_MultiTransactionManager::RemoveLastUndo | ( | ) |
Removes undo information from the list of undos of the manager and all documents which have been modified during the transaction.
◆ SetModificationMode()
| void TDocStd_MultiTransactionManager::SetModificationMode | ( | const Standard_Boolean | theTransactionOnly | ) |
If theTransactionOnly is True, denies all changes outside transactions.
◆ SetNestedTransactionMode()
| void TDocStd_MultiTransactionManager::SetNestedTransactionMode | ( | const Standard_Boolean | isAllowed = Standard_True | ) |
Sets nested transaction mode if isAllowed == Standard_True NOTE: field myIsNestedTransactionMode exists only for synchronization between several documents and has no effect on transactions of multitransaction manager.
◆ SetUndoLimit()
| void TDocStd_MultiTransactionManager::SetUndoLimit | ( | const Standard_Integer | theLimit | ) |
Sets undo limit for the manager and all documents.
◆ Undo()
| void TDocStd_MultiTransactionManager::Undo | ( | ) |
Undoes the current transaction of the manager. It calls the Undo () method of the document being on top of the manager list of undos (list.First()) and moves the list item to the top of the list of manager redos (list.Prepend(item)).
