Detailed Description
Defines services which are required to load an InterfaceModel from a File. Typically, it may firstly transform a system file into a FileReaderData object, then work on it, not longer considering file contents, to load an Interface Model. It may also work on a FileReaderData already loaded.
FileReaderTool provides, on one hand, some general services which are common to all read operations but can be redefined, plus general actions to be performed specifically for each Norm, as deferred methods to define.
In particular, FileReaderTool defines the Interface's Unknown and Error entities

Member Function Documentation

pure virtual |
Fills an Entity, given record no; specific to each Interface, called by AnalyseFile from InterfaceModel (which manages its calling arguments) To work, each Interface can define a method in its proper Transient class, like this (given as an example) : AnalyseRecord (me : mutable; FR : in out FileReaderTool; num : Integer; acheck : in out Check) returns Boolean; and call it from AnalyseRecord.
Returned Value : True if the entity could be loaded, False else (in case of syntactic fail)
Implemented in StepData_StepReaderTool, and IGESData_IGESReaderTool.

Returns the Protocol given at creation time.
|
pure virtual |
Recognizes a record, given its number. Specific to each Interface; called by SetEntities. It can call the basic method RecognizeByLib. Returns False if recognition has failed, True else. <ach> has not to be filled if simply Recognition has failed : it must record true error messages : RecognizeByLib can generate error messages if NewRead is called.
Note that it works thru a Recognizer (method Evaluate) which has to be memorized before starting
