Detailed Description
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
Member Function Documentation
◆ CaseNum()
|
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.
◆ NewRead()
|
virtual |
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.
◆ Read()
|
pure virtual |
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.
Implemented in StepData_ReadWriteModule, and IGESData_ReadWriteModule.
