Public Member Functions | |
| void | Transient (const occ::handle< TransientT > &theTransient) |
| Changes transient object. | |
| const occ::handle< TransientT > & | Import () |
| Import transient object from the persistent data. | |
 Public Member Functions inherited from StdObjMgt_Persistent | |
| StdObjMgt_Persistent () | |
| virtual void | Read (StdObjMgt_ReadData &theReadData)=0 |
| Read persistent data from a file. | |
| virtual void | Write (StdObjMgt_WriteData &theWriteData) const =0 |
| Write persistent data to a file. | |
| virtual void | PChildren (SequenceOfPersistent &) const =0 |
| Gets persistent child objects. | |
| virtual const char * | PName () const =0 |
| Returns persistent type name. | |
| virtual void | ImportDocument (const occ::handle< TDocStd_Document > &theDocument) const |
| Import transient document from the persistent data (to be overridden by document class; does nothing by default for other classes). | |
| virtual occ::handle< TDF_Attribute > | CreateAttribute () |
| Create an empty transient attribute (to be overridden by attribute classes; does nothing and returns a null handle by default for other classes). | |
| virtual occ::handle< TDF_Attribute > | GetAttribute () const |
| Get transient attribute for the persistent data (to be overridden by attribute classes; returns a null handle by default for non-attribute classes). | |
| virtual void | ImportAttribute () |
| Import transient attribute from the persistent data (to be overridden by attribute classes; does nothing by default for non-attribute classes). | |
| virtual occ::handle< TCollection_HAsciiString > | AsciiString () const |
| Get referenced ASCII string (to be overridden by ASCII string class; returns a null handle by default for other classes). | |
| virtual occ::handle< TCollection_HExtendedString > | ExtString () const |
| Get referenced extended string (to be overridden by extended string class; returns a null handle by default for other classes). | |
| virtual TDF_Label | Label (const occ::handle< TDF_Data > &theDF) const |
| Get a label expressed by referenced extended string (to be overridden by extended string class; returns a null label by default for other classes). | |
| int | TypeNum () const |
| Returns the assigned persistent type number. | |
| void | TypeNum (int theTypeNum) |
| Assigns a persistent type number to the object. | |
| int | RefNum () const |
| Returns the object reference number. | |
| void | RefNum (int theRefNum) |
| Sets an object reference number. | |
| 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. | |
Protected Attributes | |
| occ::handle< TransientT > | myTransient |
