Public Member Functions | |
| TopoDS_TCompound () | |
| Creates an empty TCompound. | |
| occ::handle< TopoDS_TShape > | EmptyCopy () const override |
| Returns an empty TCompound. | |
 Public Member Functions inherited from TopoDS_TShape | |
| bool | Free () const |
| Returns the free flag. | |
| void | Free (bool theIsFree) |
| Sets the free flag. | |
| bool | Locked () const |
| Returns the locked flag. | |
| void | Locked (bool theIsLocked) |
| Sets the locked flag. | |
| bool | Modified () const |
| Returns the modification flag. | |
| void | Modified (bool theIsModified) |
| Sets the modification flag. | |
| bool | Checked () const |
| Returns the checked flag. | |
| void | Checked (bool theIsChecked) |
| Sets the checked flag. | |
| bool | Orientable () const |
| Returns the orientability flag. | |
| void | Orientable (bool theIsOrientable) |
| Sets the orientability flag. | |
| bool | Closed () const |
| Returns the closedness flag. | |
| void | Closed (bool theIsClosed) |
| Sets the closedness flag. | |
| bool | Infinite () const |
| Returns the infinity flag. | |
| void | Infinite (bool theIsInfinite) |
| Sets the infinity flag. | |
| bool | Convex () const |
| Returns the convexness flag. | |
| void | Convex (bool theIsConvex) |
| Sets the convexness flag. | |
| TopAbs_ShapeEnum | ShapeType () const |
| Returns the type as a term of the ShapeEnum enum: VERTEX, EDGE, WIRE, FACE, SHELL, SOLID, COMPSOLID, COMPOUND. The type is embedded in the lower 4 bits of the state. | |
| int | NbChildren () const |
| Returns the number of direct sub-shapes (children). | |
| virtual void | DumpJson (Standard_OStream &theOStream, int theDepth=-1) const |
| Dumps the content of me into the stream. | |
| Public Member Functions inherited from Standard_Transient | |
| Standard_Transient () | |
| Empty constructor. | |
| Standard_Transient (const Standard_Transient &) | |
| Copy constructor – does nothing. | |
| Standard_Transient & | operator= (const Standard_Transient &) |
| Assignment operator, needed to avoid copying reference counter. | |
| virtual | ~Standard_Transient ()=default |
| Destructor must be virtual. | |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| Returns a type descriptor about this object. | |
| bool | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| Returns a true value if this is an instance of Type. | |
| bool | IsInstance (const char *const theTypeName) const |
| Returns a true value if this is an instance of TypeName. | |
| bool | IsKind (const opencascade::handle< Standard_Type > &theType) const |
| Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism. | |
| bool | IsKind (const char *const theTypeName) const |
| Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism. | |
| Standard_Transient * | This () const |
| Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero. | |
| int | GetRefCount () const noexcept |
| Get the reference counter of this object. | |
| void | IncrementRefCounter () noexcept |
| Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations. | |
| int | DecrementRefCounter () noexcept |
| Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement. | |
| virtual void | Delete () const |
| Memory deallocator for transient classes. | |

| enum | BitLayout : uint16_t { Bits_ShapeType_Mask = 0x000F , Bits_ShapeType_Shift = 0 , Bit_Free = 0x0010 , Bit_Modified = 0x0020 , Bit_Checked = 0x0040 , Bit_Orientable = 0x0080 , Bit_Closed = 0x0100 , Bit_Infinite = 0x0200 , Bit_Convex = 0x0400 , Bit_Locked = 0x0800 , Bits_Reserved = 0xF000 } |
| Bit layout for compact state storage. Bits 0-3 store the TopAbs_ShapeEnum value (0-8). Bits 4-11 store boolean flags. Bits 12-15 are reserved for future use. More... | |
