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()

virtual Standard_Integer Interface_ReaderModule::CaseNum ( const Handle< Interface_FileReaderData > &  data,
const Standard_Integer  num 
) const
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 Standard_Boolean Interface_ReaderModule::NewRead ( const Standard_Integer  casenum,
const Handle< Interface_FileReaderData > &  data,
const Standard_Integer  num,
Handle< Interface_Check > &  ach,
Handle< Standard_Transient > &  ent 
) const
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()

virtual void Interface_ReaderModule::Read ( const Standard_Integer  casenum,
const Handle< Interface_FileReaderData > &  data,
const Standard_Integer  num,
Handle< Interface_Check > &  ach,
const Handle< Standard_Transient > &  ent 
) const
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.
