| | Sets specific ID of the attribute (supports several attributes of one type at the same label feature).

|
| |
| const TDF_Label | Label () const |
| | Returns the label to which the attribute is attached. If the label is not included in a DF, the label is null. See Label. Warning If the label is not included in a data framework, it is null. This function should not be redefined inline.

| | Returns the transaction index in which the attribute has been created or modified.
|
| |
| Standard_Integer | UntilTransaction () const |

|
| |
| Standard_Boolean | IsNew () const |

| |
| Standard_Boolean | FindAttribute (const Standard_GUID &anID, Handle< TDF_Attribute > &anAttribute) const |

|
| |
| Standard_Boolean | ForgetAttribute (const Standard_GUID &aguid) const |
| | Forgets the Attribute of GUID <aguid> associated to the label of <me>. Be careful that if <me> is the attribute of <guid>, <me> will have a null label after this call. If the attribute doesn't exist returns False. Otherwise returns True.
|
| |
| void | ForgetAllAttributes (const Standard_Boolean clearChildren=Standard_True) const |
| | Forgets all the attributes attached to the label of <me>. Does it on the sub-labels if <clearChildren> is set to true. Of course, this method is compatible with Transaction & Delta mechanisms. Be careful that if <me> will have a null label after this call.
|
| |
| virtual void | AfterAddition () |
| | Something to do after adding an Attribute to a label.
|
| |
| virtual void | BeforeRemoval () |
| | Something to do before removing an Attribute from a label.
|
| |
| virtual void | BeforeForget () |
| | Something to do before forgetting an Attribute to a label.
|
| |
| virtual void | AfterResume () |
| | Something to do after resuming an Attribute from a label.
|
| |
| virtual Standard_Boolean | AfterRetrieval (const Standard_Boolean forceIt=Standard_False) |
| | Something to do AFTER creation of an attribute by persistent-transient translation. The returned status says if AfterUndo has been performed (true) or if this callback must be called once again further (false). If <forceIt> is set to true, the method MUST perform and return true. Does nothing by default and returns true.
|
| |
| virtual Standard_Boolean | BeforeUndo (const Handle< TDF_AttributeDelta > &anAttDelta, const Standard_Boolean forceIt=Standard_False) |
| | Something to do before applying <anAttDelta>. The returned status says if AfterUndo has been performed (true) or if this callback must be called once again further (false). If <forceIt> is set to true, the method MUST perform and return true. Does nothing by default and returns true.
|
| |
| virtual Standard_Boolean | AfterUndo (const Handle< TDF_AttributeDelta > &anAttDelta, const Standard_Boolean forceIt=Standard_False) |
| | Something to do after applying <anAttDelta>. The returned status says if AfterUndo has been performed (true) or if this callback must be called once again further (false). If <forceIt> is set to true, the method MUST perform and return true. Does nothing by default and returns true.
|
| |
| virtual void | BeforeCommitTransaction () |
| | A callback. By default does nothing. It is called by TDF_Data::CommitTransaction() method.
|
| |
| void | Backup () |
| | Backups the attribute. The backuped attribute is flagged "Backuped" and not "Valid".
|
| |
| Standard_Boolean | IsBackuped () const |
| | Returns true if the attribute backup status is set. This status is set/unset by the Backup() method.
|
| |
| virtual Handle< TDF_Attribute > | BackupCopy () const |
| | Copies the attribute contents into a new other attribute. It is used by Backup().
|
| |
| virtual Handle< TDF_DeltaOnAddition > | DeltaOnAddition () const |
| | Makes an AttributeDelta because <me> appeared. The only known use of a redefinition of this method is to return a null handle (no delta).
|
| |
| virtual Handle< TDF_DeltaOnForget > | DeltaOnForget () const |
| | Makes an AttributeDelta because <me> has been forgotten.
|
| |
| virtual Handle< TDF_DeltaOnResume > | DeltaOnResume () const |

| virtual Handle< TDF_DeltaOnModification > | DeltaOnModification (const Handle< TDF_Attribute > &anOldAttribute) const |
| | Makes a DeltaOnModification between <me> and.
|
| |
| virtual void | DeltaOnModification (const Handle< TDF_DeltaOnModification > &aDelta) |
| | Applies a DeltaOnModification to <me>.
|
| |
| virtual Handle< TDF_DeltaOnRemoval > | DeltaOnRemoval () const |

| | Dumps the attribute content on <aStream>, using <aMap> like this: if an attribute is not in the map, first put add it to the map and then dump it. Use the map rank instead of dumping each attribute field.
|
| |
| void | Forget (const Standard_Integer aTransaction) |
| | Forgets the attribute. <aTransaction> is the current transaction in which the forget is done. A forgotten attribute is also flagged not "Valid".
