# Interface_FileReaderTool Class Reference

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
.

## Public Member Functions

void * | operator new (size_t, void *anAddress)
void * | operator new (size_t size)
void | operator delete (void *anAddress)
Standard_EXPORT void | SetData (const Handle(Interface_FileReaderData)&reader, const Handle(Interface_Protocol)&protocol)
| Sets Data to a FileReaderData. Works with a Protocol .
Standard_EXPORT Handle_Interface_Protocol | Protocol () const
| Returns the Protocol given at creation time .
Standard_EXPORT Handle_Interface_FileReaderData | Data () const
| Returns the FileReaderData which is used to work .
Standard_EXPORT void | SetModel (const Handle(Interface_InterfaceModel)&amodel)
| Stores a Model. Used when the Model has been loaded .
Standard_EXPORT Handle_Interface_InterfaceModel | Model () const
| Returns the stored Model .
Standard_EXPORT void | SetMessenger (const Handle(Message_Messenger)&messenger)
| Sets Messenger used for outputting messages .
Standard_EXPORT Handle_Message_Messenger | Messenger () const
| Returns Messenger used for outputting messages. The returned object is guaranteed to be non-null; default is Message::Messenger(). .
Standard_EXPORT void | SetTraceLevel (const Standard_Integer tracelev)
| Sets trace level used for outputting messages - 0: no trace at all - 1: errors - 2: errors and warnings - 3: all messages Default is 1 : Errors traced .
Standard_EXPORT Standard_Integer | TraceLevel () const
| Returns trace level used for outputting messages. .
Standard_EXPORT 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 .
Standard_EXPORT Standard_Boolean | ErrorHandle () const
| Returns ErrorHandle flag .
Standard_EXPORT 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 .
virtual Standard_EXPORT Standard_Boolean | Recognize (const Standard_Integer num, Handle(Interface_Check)&ach, Handle(Standard_Transient)&ent)=0

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
.

Standard_EXPORT 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
.

Standard_EXPORT 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 .
Standard_EXPORT Handle_Interface_InterfaceModel | NewModel () const
| Creates an empty Model of the norm. Uses Protocol to do it .
Standard_EXPORT 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.
.

Standard_EXPORT 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 .
virtual Standard_EXPORT void | BeginRead (const Handle(Interface_InterfaceModel)&amodel)=0
| Fills model's header; each Interface defines for its Model its own file header; this method fills it from FileReaderTool.+ It is called by AnalyseFile from InterfaceModel .
virtual Standard_EXPORT Standard_Boolean | AnalyseRecord (const Standard_Integer num, const Handle(Standard_Transient)&anent, Handle(Interface_Check)&acheck)=0

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)
.

virtual Standard_EXPORT void | Destroy ()
virtual Standard_EXPORT | ~Interface_FileReaderTool ()
virtual Standard_EXPORT void | EndRead (const Handle(Interface_InterfaceModel)&amodel)
| Ends file reading after reading all the entities default is doing nothing; redefinable as necessary .
