OCC.TopAbs module¶
applications such as : Topological Data Structure,Topological Algorithms.It contains :* The ShapeEnum enumeration to describe thedifferents topological shapes.* The Orientation enumeration to describe theorientation of a topological shape.* The State enumeration to describes theposition of a point relative to a Shape.* Methods to manage the enumerations.-Level : Public.All methods of all classes will be public.

Complement()¶ - Reverses the interior/exterior status of each side of the object. So, to take the complement of an object means to reverse the interior/exterior status of its boundary, i.e. inside becomes outside. The method returns the complementary orientation, following the rules in the table below: FORWARD REVERSED REVERSED FORWARD INTERNAL EXTERNAL EXTERNAL INTERNAL //! Complement complements the material side. Inside becomes outside.
Parameters: Or (TopAbs_Orientation) – Return type: TopAbs_Orientation
-
static
Compose()¶ - Compose the Orientation <Or1> and <Or2>. This composition is not symmetric (if you switch <Or1> and <Or2> the result is different). It assumes that <Or1> is the Orientation of a Shape S1 containing a Shape S2 of Orientation Or2. The result is the cumulated orientation of S2 in S1. The composition law is : //! Or2 FORWARD REVERSED INTERNAL EXTERNAL Or1 ————————————- FORWARD | FORWARD REVERSED INTERNAL EXTERNAL | REVERSED | REVERSED FORWARD INTERNAL EXTERNAL | INTERNAL | INTERNAL INTERNAL INTERNAL INTERNAL | EXTERNAL | EXTERNAL EXTERNAL EXTERNAL EXTERNAL Note: The top corner in the table is the most important for the purposes of Open CASCADE topology and shape sharing.
Parameters: - Or1 (TopAbs_Orientation) –
- Or2 (TopAbs_Orientation) –
Return type: TopAbs_Orientation

static
Print()¶ - Prints the name of Shape <SEq> as a String on the Stream <S> and returns <S>.
Parameters: - SE (TopAbs_ShapeEnum) –
- S (Standard_OStream &) –
Return type: Standard_OStream
- Prints the name of the Orientation <Or> as a String on the Stream <S> and returns <S>.
Parameters: - Or (TopAbs_Orientation) –
- S (Standard_OStream &) –
Return type: Standard_OStream
- Prints the name of the State <St> as a String on the Stream <S> and returns <S>.
Parameters: - St (TopAbs_State) –
- S (Standard_OStream &) –
Return type: Standard_OStream

static
Reverse()¶ - xchanges the interior/exterior status of the two sides. This is what happens when the sense of direction is reversed. The following rules apply: //! FORWARD REVERSED REVERSED FORWARD INTERNAL INTERNAL EXTERNAL EXTERNAL //! Reverse exchange the material sides.
Parameters: Or (TopAbs_Orientation) – Return type: TopAbs_Orientation
-

Parameters: Or (TopAbs_Orientation) – Return type: TopAbs_Orientation

It assumes that <Or1> is the Orientation of a Shape S1 containing a Shape S2 of Orientation Or2. The result is the cumulated orientation of S2 in S1. The composition law is : //!
