The basis to define a point attribute.
The topological attribute must contain a vertex.
You use this class to create reference points in a design.
Warning: Use TDataXtd_Geometry attribute to retrieve the
gp_Pnt of the Point attribute

Public Member Functions | |
TDataXtd_Point () | |
const Standard_GUID & | ID () const |
Returns the ID of the attribute. | |
void | Restore (const Handle< TDF_Attribute > &With) |
Restores the backuped contents from <anAttribute> into this one. It is used when aborting a transaction. | |
Handle_TDF_Attribute | NewEmpty () const |
Returns an new empty attribute from the good end type. It is used by the copy algorithm. | |
void | Paste (const Handle< TDF_Attribute > &Into, const Handle< TDF_RelocationTable > &RT) const |
This method is different from the "Copy" one, because it is used when copying an attribute from a source structure into a target structure. This method may paste the contents of <me> into <intoAttribute>. The given pasted attribute can be full or empty of its contents. But don't make a NEW! Just set the contents! It is possible to use <aRelocationTable> to get/set the relocation value of a source attribute. | |
virtual Standard_OStream & | Dump (Standard_OStream &anOS) const |
Dumps the minimum information about <me> on <aStream>. | |

static const Standard_GUID & | GetID () |
class methods ============= Returns the GUID for point attributes. | |
static Handle_TDataXtd_Point | Set (const TDF_Label &label) |
Sets the label Label as a point attribute. If no object is found, a point attribute is created. | |
static Handle_TDataXtd_Point | Set (const TDF_Label &label, const gp_Pnt &P) |
Sets the label Label as a point attribute containing the point P. If no object is found, a point attribute is created. //! Point methods ============= |
