IGESData_IGESReaderTool (const Handle< IGESData_IGESReaderData > &reader, const Handle< IGESData_Protocol > &protocol) | |

void | Prepare (const Handle< IGESData_FileRecognizer > &reco) |
binds empty entities to records, works with the Protocol (from IGESData) stored and later used RQ : Actually, sets DNum into IGES Entities Also loads the list of parameters for ParamReader More... | |
Standard_Boolean | Recognize (const Standard_Integer num, Handle< Interface_Check > &ach, Handle< Standard_Transient > &ent) override |

Standard_Boolean | AnalyseRecord (const Standard_Integer num, const Handle< Standard_Transient > &anent, Handle< Interface_Check > &acheck) override |
fills an entity, given record no; works by calling ReadDirPart then ReadParams (with help of a ParamReader), then if required ReadProps and ReadAssocs, from IGESEntity Returns True if no fail has been recorded More... | |

void | ReadOwnParams (const Handle< IGESData_IGESEntity > &ent, const Handle< IGESData_IGESReaderData > &IR, IGESData_ParamReader &PR) const |
Performs Reading of own Parameters for each IGESEntity Works with the ReaderLib loaded with ReadWriteModules for IGES In case of failure, tries UndefinedEntity from IGES. More... | |
void | ReadProps (const Handle< IGESData_IGESEntity > &ent, const Handle< IGESData_IGESReaderData > &IR, IGESData_ParamReader &PR) const |
Reads Property List, if there is (if not, does nothing) criterium is : current parameter of PR remains inside params list, and Stage is "Own" Current parameter must be a positive integer, which value gives the length of the list; else, a Fail is produced (into Check of PR) and reading process is stopped. More... | |

Reads Associativity List, if there is (if not, does nothing) criterium is : current parameter of PR remains inside params list, and Stage is "Own" Same conditions as above; in addition, no parameter must be let after the list once read Note that "Associated" entities are not declared "Shared".

void | SetData (const Handle< Interface_FileReaderData > &reader, const Handle< Interface_Protocol > &protocol) |
Sets Data to a FileReaderData. Works with a Protocol. More... | |
Handle< Interface_Protocol > | Protocol () const |
Returns the Protocol given at creation time. More... | |
Handle< Interface_FileReaderData > | Data () const |
Returns the FileReaderData which is used to work. More... | |
void | SetModel (const Handle< Interface_InterfaceModel > &amodel) |
Stores a Model. Used when the Model has been loaded. More... | |
Handle< Interface_InterfaceModel > | Model () const |
Returns the stored Model. More... | |
void | SetMessenger (const Handle< Message_Messenger > &messenger) |
Sets Messenger used for outputting messages. More... | |
Handle< Message_Messenger > | Messenger () const |
Returns Messenger used for outputting messages. The returned object is guaranteed to be non-null; default is Message::Messenger(). More... | |
void | SetTraceLevel (const Standard_Integer tracelev) |
Sets trace level used for outputting messages. More... | |
Standard_Integer | TraceLevel () const |
Returns trace level used for outputting messages. More... | |
void | SetErrorHandle (const Standard_Boolean err) |
Allows controlling whether exception raisings are handled If err is False, they are not (hence, dbx can take control) If err is True, they are, and they are traced (by putting on messenger Entity's Number and file record num) Default given at Model's creation time is True. More... | |
Standard_Boolean | ErrorHandle () const |
Returns ErrorHandle flag. More... | |
void | SetEntities () |
Fills records with empty entities; once done, each entity can ask the FileReaderTool for any entity referenced through an identifier. Calls Recognize which is specific to each specific type of FileReaderTool. More... | |
Standard_Boolean | RecognizeByLib (const Standard_Integer num, Interface_GeneralLib &glib, Interface_ReaderLib &rlib, Handle< Interface_Check > &ach, Handle< Standard_Transient > &ent) const |
Recognizes a record with the help of Libraries. Can be used to implement the method Recognize. <rlib> is used to find Protocol and CaseNumber to apply <glib> performs the creation (by service NewVoid, or NewRead if NewVoid gave no result) <ach> is a check, which is transmitted to NewRead if it is called, gives a result but which is false <ent> is the result Returns False if recognition has failed, True else. More... | |
Handle< Standard_Transient > | UnknownEntity () const |
Provides an unknown entity, specific to the Interface called by SetEntities when Recognize has failed (Unknown alone) or by LoadModel when an Entity has caused a Fail on reading (to keep at least its literal description) Uses Protocol to do it. More... | |
Handle< Interface_InterfaceModel > | NewModel () const |
Creates an empty Model of the norm. Uses Protocol to do it. More... | |
void | LoadModel (const Handle< Interface_InterfaceModel > &amodel) |
Reads and fills Entities from the FileReaderData set by SetData to an InterfaceModel. It enchains required operations, the specific ones correspond to deferred methods (below) to be defined for each Norm. It manages also error recovery and trace. Remark : it calls SetModel. It Can raise any error which can occur during a load operation, unless Error Handling is set. This method can also be redefined if judged necessary. More... | |
Handle< Standard_Transient > | LoadedEntity (const Standard_Integer num) |
Reads, Fills and Returns one Entity read from a Record of the FileReaderData. This Method manages also case of Fail or Warning, by producing a ReportEntyty plus , for a Fail, a literal Content (as an UnknownEntity). Performs also Trace. More... | |
