Standard_EXPORT | TDF_Label () |
Constructs an empty label object. . | |
void | Nullify () |
Nullifies the label. . | |
Handle_TDF_Data | Data () const |
Returns the Data owning <me>. . | |
Standard_Integer | Tag () const |
Returns the tag of the label. This is the integer assigned randomly to a label in a data framework. This integer is used to identify this label in an entry. . | |
const TDF_Label | Father () const |
Returns the label father. This label may be null if the label is root. . | |
Standard_Boolean | IsNull () const |
Returns True if the <alabel> is null, i.e. it has not been included in the data framework. . | |
Standard_EXPORT void | Imported (const Standard_Boolean aStatus) const |
Sets or unsets <me> and all its descendants as imported label, according to <astatus>. . | |
Standard_Boolean | IsImported () const |
Returns True if the <alabel> is imported. . | |
Standard_Boolean | IsEqual (const TDF_Label &aLabel) const |
Returns True if the <alabel> is equal to me (same LabelNode*). . | |
Standard_Boolean | operator== (const TDF_Label &aLabel) const |
Standard_Boolean | IsDifferent (const TDF_Label &aLabel) const |
Standard_Boolean | operator!= (const TDF_Label &aLabel) const |
Standard_Boolean | IsRoot () const |
Standard_EXPORT Standard_Boolean | IsAttribute (const Standard_GUID &anID) const |
Returns true if <me> owns an attribute with <anid> as ID. . | |
Standard_EXPORT void | AddAttribute (const Handle(TDF_Attribute)&anAttribute) const |
Adds an Attribute to the current label. Raises if there is already one. . | |
Standard_EXPORT void | ForgetAttribute (const Handle(TDF_Attribute)&anAttribute) const |
Forgets an Attribute from the current label, setting its forgotten status true and its valid status false. Raises if the attribute is not in the structure. . | |
Standard_EXPORT Standard_Boolean | ForgetAttribute (const Standard_GUID &aguid) const |
Forgets the Attribute of GUID <aguid> from the current label . If the attribute doesn't exist returns False. Otherwise returns True. . | |
Standard_EXPORT void | ForgetAllAttributes (const Standard_Boolean clearChildren=Standard_True) const |
Forgets all the attributes. Does it on also on the sub-labels if <clearchildren> is set to true. Of course, this method is compatible with Transaction & Delta mecanisms. . | |
Standard_EXPORT void | ResumeAttribute (const Handle(TDF_Attribute)&anAttribute) const |
Undo Forget action, setting its forgotten status false and its valid status true. Raises if the attribute is not in the structure. . | |
Standard_EXPORT Standard_Boolean | FindAttribute (const Standard_GUID &anID, Handle(TDF_Attribute)&anAttribute) const |
Finds an attribute of the current label, according to <anid>. If anAttribute is not a valid one, false is returned. The method returns True if found, False otherwise. A removed attribute cannot be found. . | |
Standard_EXPORT Standard_Boolean | FindAttribute (const Standard_GUID &anID, const Standard_Integer aTransaction, Handle(TDF_Attribute)&anAttribute) const |
Finds an attribute of the current label, according to <anid> and <atransaction>. This attribute has/had to be a valid one for the given transaction index . So, this attribute is not necessary a valid one. The method returns True if found, False otherwise. A removed attribute cannot be found nor a backuped attribute of a removed one. . | |
Standard_Boolean | MayBeModified () const |
Returns true if <me> or a DESCENDANT of <me> owns attributes not yet available in transaction 0. It means at least one of their attributes is new, modified or deleted. . | |
Standard_Boolean | AttributesModified () const |
Returns true if <me> owns attributes not yet available in transaction 0. It means at least one attribute is new, modified or deleted. . | |
Standard_EXPORT Standard_Boolean | HasAttribute () const |
Returns true if this label has at least one attribute. . | |
Standard_EXPORT Standard_Integer | NbAttributes () const |
Returns the number of attributes. . | |
Standard_EXPORT Standard_Integer | Depth () const |
Returns the depth of the label in the data framework. This corresponds to the number of fathers which this label has, and is used in determining whether a label is root, null or equivalent to another label. Exceptions: Standard_NullObject if this label is null. This is because a null object can have no depth. . | |
Standard_EXPORT Standard_Boolean | IsDescendant (const TDF_Label &aLabel) const |
Returns True if <me> is a descendant of <alabel>. Attention: every label is its own descendant. . | |
Standard_EXPORT const TDF_Label | Root () const |
Returns the root label Root of the data structure. This has a depth of 0. Exceptions: Standard_NullObject if this label is null. This is because a null object can have no depth. . | |
Standard_Boolean | HasChild () const |
Returns true if this label has at least one child. . | |
Standard_EXPORT Standard_Integer | NbChildren () const |
Returns the number of children. . | |
Standard_EXPORT TDF_Label | FindChild (const Standard_Integer aTag, const Standard_Boolean create=Standard_True) const |
Finds a child label having <atag> as tag. Creates The tag aTag identifies the label which will be the parent. If create is true and no child label is found, a new one is created. Example: //creating a label with tag 10 at Root TDF_Label lab1 = aDF->Root().FindChild(10); //creating labels 7 and 2 on label 10 TDF_Label lab2 = lab1.FindChild(7); TDF_Label lab3 = lab1.FindChild(2); . | |
TDF_Label | NewChild () const |
Create a new child label of me using autoamtic delivery tags provided by TagSource. . | |
Standard_EXPORT Standard_Integer | Transaction () const |
Returns the current transaction index. . | |
Standard_EXPORT Standard_Boolean | HasLowerNode (const TDF_Label &otherLabel) const |
Returns true if node address of <me> is lower than <otherlabel> one. Used to quickly sort labels (not on entry criterion). -C++: inline . | |
Standard_EXPORT Standard_Boolean | HasGreaterNode (const TDF_Label &otherLabel) const |
Returns true if node address of <me> is greater than <otherlabel> one. Used to quickly sort labels (not on entry criterion). -C++: inline . | |
Standard_EXPORT Standard_OStream & | Dump (Standard_OStream &anOS) const |
Dumps the minimum information about <me> on <astream>. . | |
Standard_OStream & | operator<< (Standard_OStream &anOS) const |
Standard_EXPORT void | ExtendedDump (Standard_OStream &anOS, const TDF_IDFilter &aFilter, TDF_AttributeIndexedMap &aMap) const |
Dumps the label on <astream> and its attributes rank in <amap> if their IDs are kept by <idfilter>. . | |
Standard_EXPORT void | EntryDump (Standard_OStream &anOS) const |
Dumps the label entry. . | |

Standard_EXPORT | TDF_Label (const TDF_LabelNodePtr &aNode) |
Reserved to the friends. . | |
Standard_EXPORT void | AddToNode (const TDF_LabelNodePtr &toNode, const Handle(TDF_Attribute)&anAttribute) const |
Adds an Attribute to <tonode>. Raises if there is already one. . | |
Standard_EXPORT void | ForgetFromNode (const TDF_LabelNodePtr &fromNode, const Handle(TDF_Attribute)&anAttribute) const |
Forgets an Attribute from <fromnode>. Raises if the attribute is not in the structure. . | |
Standard_EXPORT void | ResumeToNode (const TDF_LabelNodePtr &fromNode, const Handle(TDF_Attribute)&anAttribute) const |
Resumes a forgotten Attribute to <tonode>. Raises if the attribute is not in the structure. . | |
