Public Member Functions | |
Standard_EXPORT | TDocStd_Document (const TCollection_ExtendedString &astorageformat) |
Constructs a document object defined by the string astorageformat. . | |
Standard_EXPORT Standard_Boolean | IsSaved () const |
the document is saved in a file. | |
Standard_Boolean | IsChanged () const |
returns True if document differs from the state of last saving. this method have to be called only wroking in the transaction mode | |
void | SetSaved () |
This method have to be called to show document that it has been saved . | |
void | SetSavedTime (const Standard_Integer theTime) |
Say to document what it is not saved. Use value, returned earlier by GetSavedTime(). . | |
Standard_Integer | GetSavedTime () const |
Returns value of <mysavedtime> to be used later in SetSavedTime() . | |
Standard_EXPORT TCollection_ExtendedString | GetName () const |
raise if <me> is not saved. | |
Standard_EXPORT TCollection_ExtendedString | GetPath () const |
returns the OS path of the file, in wich one <me> is saved. Raise an exception if <me> is not saved. | |
Standard_EXPORT void | SetData (const Handle(TDF_Data)&data) |
Standard_EXPORT Handle_TDF_Data | GetData () const |
Standard_EXPORT TDF_Label | Main () const |
Returns the main label in this data framework. By definition, this is the label with the entry 0:1. . | |
Standard_EXPORT Standard_Boolean | IsEmpty () const |
Returns True if the main label has no attributes . | |
Standard_EXPORT Standard_Boolean | IsValid () const |
Returns False if the document has been modified but not recomputed. . | |
Standard_EXPORT void | SetModified (const TDF_Label &L) |
Notify the label as modified, the Document becomes UnValid. //! returns True if <l> has been notified as modified. . | |
Standard_EXPORT void | PurgeModified () |
Remove all modifications. After this call The document becomesagain Valid. . | |
Standard_EXPORT const TDF_LabelMap & | GetModified () const |
Returns the labels which have been modified in this document. . | |
Standard_EXPORT void | NewCommand () |
Launches a new command. This command may be undone. . | |
Standard_EXPORT Standard_Boolean | HasOpenCommand () const |
returns True if a Command transaction is open in the curret . | |
Standard_EXPORT void | OpenCommand () |
Opens a new command transaction in this document. You can use HasOpenCommand to see whether a command is already open. Exceptions Standard_DomainError if a command is already open in this document. . | |
Standard_EXPORT Standard_Boolean | CommitCommand () |
Commits documents transactions and fills the transaction manager with documents that have been changed during the transaction. If no command transaction is open, nothing is done. Returns True if a new delta has been added to myUndos. . | |
Standard_EXPORT void | AbortCommand () |
Abort the Command transaction. Does nothing If there is no Command transaction open. . | |
Standard_EXPORT Standard_Integer | GetUndoLimit () const |
The current limit on the number of undos . | |
Standard_EXPORT void | SetUndoLimit (const Standard_Integer L) |
Set the limit on the number of Undo Delta stored 0 will disable Undo on the document A negative value means no limit. Note that by default Undo is disabled. Enabling it will take effect with the next call to NewCommand. Of course this limit is the same for Redo . | |
Standard_EXPORT void | ClearUndos () |
Remove all stored Undos and Redos . | |
Standard_EXPORT void | ClearRedos () |
Remove all stored Redos . | |
Standard_EXPORT Standard_Integer | GetAvailableUndos () const |
Returns the number of undos stored in this document. If this figure is greater than 0, the method Undo can be used. . | |
Standard_EXPORT Standard_Boolean | Undo () |
Will UNDO one step, returns False if no undo was done (Undos == 0). Otherwise, true is returned and one step in the list of undoes is undone. . | |
Standard_EXPORT Standard_Integer | GetAvailableRedos () const |
Returns the number of redos stored in this document. If this figure is greater than 0, the method Redo can be used. . | |
Standard_EXPORT Standard_Boolean | Redo () |
Will REDO one step, returns False if no redo was done (Redos == 0). Otherwise, true is returned, and one step in the list of redoes is done again. . | |
Standard_EXPORT const TDF_DeltaList & | GetUndos () const |
Standard_EXPORT const TDF_DeltaList & | GetRedos () const |
Standard_EXPORT void | RemoveFirstUndo () |
Removes the first undo in the list of document undos. It is used in the application when the undo limit is exceed. . | |
Standard_EXPORT Standard_Boolean | InitDeltaCompaction () |
Initializes the procedure of delta compaction Returns false if there is no delta to compact Marks the last delta as a "from" delta . | |
Standard_EXPORT Standard_Boolean | PerformDeltaCompaction () |
Performs the procedure of delta compaction Makes all deltas starting from "from" delta till the last one to be one delta. . | |
Standard_EXPORT void | UpdateReferences (const TCollection_AsciiString &aDocEntry) |
Set modifications on labels impacted by external references to the entry. The document becomes invalid and must be recomputed. . | |
Standard_EXPORT void | Recompute () |
Recompute if the document was not valid and propagate the reccorded modification. . | |
virtual Standard_EXPORT void | Update (const Handle(CDM_Document)&aToDocument, const Standard_Integer aReferenceIdentifier, const Standard_Address aModifContext) |
This method Update will be called to signal the end of the modified references list. The document should be recomputed and UpdateFromDocuments should be called. Update should returns True in case of success, false otherwise. In case of Failure, additional information can be given in ErrorString. //! Update the document by propagation ================================== //! Update the document from internal stored modifications. If you want to undoing this operation, please call NewCommand before. //! to change format (advanced programming) ================ . | |
virtual Standard_EXPORT TCollection_ExtendedString | StorageFormat () const |
The Storage Format is the key which is used to determine in the application resources the storage driver plugin, the file extension and other data used to store the document. . | |
virtual Standard_EXPORT void | ChangeStorageFormat (const TCollection_ExtendedString &newStorageFormat) |
methods for the nested transaction mode | |
Standard_EXPORT void | SetNestedTransactionMode (const Standard_Boolean isAllowed=Standard_True) |
Sets nested transaction mode if isAllowed == Standard_True . | |
Standard_Boolean | IsNestedTransactionMode () const |
Returns Standard_True if mode is set . | |
void | SetModificationMode (const Standard_Boolean theTransactionOnly) |
if theTransactionOnly is True changes is denied outside transactions | |
Standard_Boolean | ModificationMode () const |
returns True if changes allowed only inside transactions | |
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const |
Static Public Member Functions | |
static Standard_EXPORT Handle_TDocStd_Document | Get (const TDF_Label &L) |
