Standard_EXPORT | TDocStd_MultiTransactionManager () |
Constructor . | |
Standard_EXPORT void | SetUndoLimit (const Standard_Integer theLimit) |
Sets undo limit for the manager and all documents. . | |
Standard_Integer | GetUndoLimit () const |
Returns undo limit for the manager. . | |
Standard_EXPORT void | 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)). . | |
Standard_EXPORT void | 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)). . | |
const TDocStd_SequenceOfApplicationDelta & | GetAvailableUndos () const |
Returns available manager undos. . | |
const TDocStd_SequenceOfApplicationDelta & | GetAvailableRedos () const |
Returns available manager redos. . | |
Standard_EXPORT void | 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. . | |
Standard_EXPORT void | AbortCommand () |
Unsets the flag of started manager transaction and aborts transaction in each document. . | |
Standard_EXPORT Standard_Boolean | CommitCommand () |
Commits transaction in all documents and fills the transaction manager with the documents that have been changed during the transaction. Returns True if new data has been added to myUndos. NOTE: All nested transactions in the documents will be commited. . | |
Standard_EXPORT Standard_Boolean | CommitCommand (const TCollection_ExtendedString &theName) |
Makes the same steps as the previous function but defines the name for transaction. Returns True if new data has been added to myUndos. . | |
Standard_Boolean | HasOpenCommand () const |
Returns true if a transaction is opened. . | |
Standard_EXPORT void | RemoveLastUndo () |
Removes undo information from the list of undos of the manager and all documents which have been modified during the transaction. . | |
Standard_EXPORT void | DumpTransaction (Standard_OStream &theOS) const |
Dumps transactions in undos and redos . | |
Standard_EXPORT void | AddDocument (const Handle(TDocStd_Document)&theDoc) |
Adds the document to the transaction manager and checks if it has been already added . | |
Standard_EXPORT void | RemoveDocument (const Handle(TDocStd_Document)&theDoc) |
Removes the document from the transaction manager. . | |
const TDocStd_SequenceOfDocument & | Documents () const |
Returns the added documents to the transaction manager. . | |
Standard_EXPORT void | 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. . | |
Standard_Boolean | IsNestedTransactionMode () const |
Returns Standard_True if NestedTransaction mode is set. //! Methods for protection of changes outside transactions . | |
Standard_EXPORT void | SetModificationMode (const Standard_Boolean theTransactionOnly) |
If theTransactionOnly is True, denies all changes outside transactions. . | |
Standard_Boolean | ModificationMode () const |
Returns True if changes are allowed only inside transactions. . | |
Standard_EXPORT void | ClearUndos () |
Clears undos in the manager and in documents. . | |
Standard_EXPORT void | ClearRedos () |
Clears redos in the manager and in documents. . | |
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const |
