Public Member Functions | |
| virtual Standard_Integer | CaseNum (const Handle< Interface_FileReaderData > &data, const Standard_Integer num) const =0 |
| Translates the type of record <num> in <data> to a positive Case Number. If Recognition fails, must return 0. | |
| virtual void | Read (const Standard_Integer casenum, const Handle< Interface_FileReaderData > &data, const Standard_Integer num, Handle< Interface_Check > &ach, const Handle< Standard_Transient > &ent) const =0 |
| Performs the effective loading from <data>, record <num>, to the Entity <ent> formerly created In case of Error or Warning, fills <ach> with messages Remark that the Case Number comes from translating a record. | |
| virtual Standard_Boolean | NewRead (const Standard_Integer casenum, const Handle< Interface_FileReaderData > &data, const Standard_Integer num, Handle< Interface_Check > &ach, Handle< Standard_Transient > &ent) const |
| Specific operator (create+read) defaulted to do nothing. It can be redefined when it is not possible to work in two steps (NewVoid then Read). This occurs when no default constructor is defined : hence the result <ent> must be created with an effective definition from the reader. Remark : if NewRead is defined, Copy has nothing to do. | |
 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 () |
| Destructor must be virtual. | |
| virtual const opencascade::handle< Standard_Type > & | DynamicType () const |
| Returns a type descriptor about this object. | |
| Standard_Boolean | IsInstance (const opencascade::handle< Standard_Type > &theType) const |
| Returns a true value if this is an instance of Type. | |
| Standard_Boolean | IsInstance (const Standard_CString theTypeName) const |
| Returns a true value if this is an instance of TypeName. | |
| Standard_Boolean | 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. | |
| Standard_Boolean | IsKind (const Standard_CString 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. | |
| Standard_Integer | GetRefCount () const noexcept |
| Get the reference counter of this object. | |
| void | IncrementRefCounter () noexcept |
| Increments the reference counter of this object. | |
| Standard_Integer | DecrementRefCounter () noexcept |
| Decrements the reference counter of this object; returns the decremented value. | |
| virtual void | Delete () const |
| Memory deallocator for transient classes. | |
Additional Inherited Members | |
| typedef void | base_type |
| Returns a type descriptor about this object. | |
| static constexpr const char * | get_type_name () |
| Returns a type descriptor about this object. | |
| static const opencascade::handle< Standard_Type > & | get_type_descriptor () |
| Returns type descriptor of Standard_Transient class. | |
Defines unitary operations required to read an Entity from a File (see FileReaderData, FileReaderTool), under control of a FileReaderTool. The initial creation is performed by a GeneralModule (set in GeneralLib). Then, which remains is Loading data from the FileReaderData to the Entity.
To work, a GeneralModule has formerly recognized the Type read from FileReaderData as a positive Case Number, then the ReaderModule reads it according to this Case Number

pure virtual |
Translates the type of record <num> in <data> to a positive Case Number. If Recognition fails, must return 0.
Implemented in IGESData_ReadWriteModule, and StepData_ReadWriteModule.

Specific operator (create+read) defaulted to do nothing. It can be redefined when it is not possible to work in two steps (NewVoid then Read). This occurs when no default constructor is defined : hence the result <ent> must be created with an effective definition from the reader. Remark : if NewRead is defined, Copy has nothing to do.
Returns True if it has produced something, false else. If nothing was produced, <ach> should be filled : it will be treated as "Unrecognized case" by reader tool.
