A tool to get information on the topology of a named shape attribute. This information is typically a TopoDS_Shape object. Using this tool, relations between named shapes are also accessible.

| static TopoDS_Shape | CurrentShape (const occ::handle< TNaming_NamedShape > &NS) |
| | Returns the last Modification of <NS>. Returns the shape CurrentShape contained in the named shape attribute NS. CurrentShape is the current state of the entities if they have been modified in other attributes of the same data structure. Each call to this function creates a new compound.
|
| |
| static TopoDS_Shape | CurrentShape (const occ::handle< TNaming_NamedShape > &NS, const NCollection_Map< TDF_Label > &Updated) |
| | Returns the shape CurrentShape contained in the named shape attribute NS, and present in the updated attribute map Updated. CurrentShape is the current state of the entities if they have been modified in other attributes of the same data structure. Each call to this function creates a new compound. Warning Only the contents of Updated are searched.R.

| |
| static occ::handle< TNaming_NamedShape > | CurrentNamedShape (const occ::handle< TNaming_NamedShape > &NS, const NCollection_Map< TDF_Label > &Updated) |
| | Returns the NamedShape of the last Modification of <NS>. This shape is identified by a label.
|
| |
| static occ::handle< TNaming_NamedShape > | CurrentNamedShape (const occ::handle< TNaming_NamedShape > &NS) |
| | Returns NamedShape the last Modification of <NS>.
|
| |
| static occ::handle< TNaming_NamedShape > | NamedShape (const TopoDS_Shape &aShape, const TDF_Label &anAcces) |
| | Returns the named shape attribute defined by the shape aShape and the label anAccess. This attribute is returned as a new shape. You call this function, if you need to create a topological attribute for existing data. Example class MyPkg_MyClass { public: bool SameEdge(const
occ::handle<OCafTest_Line>& , const
occ::handle<CafTest_Line>& ); };.
|
| |
| static TopoDS_Shape | GetShape (const occ::handle< TNaming_NamedShape > &NS) |
| | Returns the entities stored in the named shape attribute NS. If there is only one old-new pair, the new shape is returned. Otherwise, a Compound is returned. This compound is made out of all the new shapes found. Each call to this function creates a new compound.
|
| |
| static TopoDS_Shape | OriginalShape (const occ::handle< TNaming_NamedShape > &NS) |
| | Returns the shape contained as OldShape in <NS>
|
| |
| static TopoDS_Shape | GeneratedShape (const TopoDS_Shape &S, const occ::handle< TNaming_NamedShape > &Generation) |
| | Returns the shape generated from S or by a modification of S and contained in the named shape Generation.
|

| static void | Collect (const occ::handle< TNaming_NamedShape > &NS, NCollection_Map< occ::handle< TNaming_NamedShape > > &Labels, const bool OnlyModif=true) |
| |
| static bool | HasLabel (const TDF_Label &access, const TopoDS_Shape &aShape) |
| | Returns True if <aShape> appears under a label.(DP)
|
| |
| static TDF_Label | Label (const TDF_Label &access, const TopoDS_Shape &aShape, int &TransDef) |
| | Returns the label of the first apparition of <aShape>. Transdef is a value of the transaction of the first apparition of <aShape>.
|
| |
| static TopoDS_Shape | InitialShape (const TopoDS_Shape &aShape, const TDF_Label &anAcces, NCollection_List< TDF_Label > &Labels) |
| | Returns the shape created from the shape aShape contained in the attribute anAcces.
|
| |
| static int | ValidUntil (const TDF_Label &access, const TopoDS_Shape &S) |
| | Returns the last transaction where the creation of S is valid.
|
| |
| static void | FindShape (const NCollection_Map< TDF_Label > &Valid, const NCollection_Map< TDF_Label > &Forbiden, const occ::handle< TNaming_NamedShape > &Arg, TopoDS_Shape &S) |
| | Returns the current shape (a Wire or a Shell) built (in the data framework) from the shapes of the argument named shape. It is used for IDENTITY name type computation.

A tool to get information on the topology of a named shape attribute. This information is typically a TopoDS_Shape object. Using this tool, relations between named shapes are also accessible.
Returns the named shape attribute defined by the shape aShape and the label anAccess. This attribute is returned as a new shape. You call this function, if you need to create a topological attribute for existing data. Example class MyPkg_MyClass { public: bool SameEdge(const
occ::handle<OCafTest_Line>& , const
occ::handle<CafTest_Line>& ); };.
bool MyPkg_MyClass::SameEdge (const occ::handle<OCafTest_Line>& L1 const occ::handle<OCafTest_Line>& L2) { occ::handle<TNaming_NamedShape> NS1 = L1->NamedShape(); occ::handle<TNaming_NamedShape> NS2 = L2->NamedShape();
return BRepTools::Compare(NS1->Get(),NS2->Get()); } In the example above, the function SameEdge is created to compare the edges having two lines for geometric supports. If these edges are found by BRepTools::Compare to be within the same tolerance, they are considered to be the same. Warning To avoid sharing of names, a SELECTED attribute will not be returned. Sharing of names makes it harder to manage the data structure. When the user of the name is removed, for example, it is difficult to know whether the name should be destroyed.
