    Public Member Functions

    bool Evaluate (const TCollection_AsciiString &akey, occ::handle< Standard_Transient > &resres)
     Evaluates if recognition has a result, returns it if yes In case of success, Returns True and puts result in "res" In case of Failure, simply Returns False Works by calling deferred method Eval, and in case of failure, looks for Added Recognizers to work.
    occ::handle< Standard_TransientResult () const
     Returns result of last recognition (call of Evaluate).
    void Add (const occ::handle< StepData_FileRecognizer > &reco)
     Adds a new Recognizer to the Compound, at the end Several calls to Add work by adding in the order of calls : Hence, when Eval has failed to recognize, Evaluate will call Evaluate from the first added Recognizer if there is one, and to the second if there is still no result, and so on.
    Public Member Functions inherited from Standard_Transient
     Standard_Transient ()
     Empty constructor.
     Standard_Transient (const Standard_Transient &)
     Copy constructor – does nothing.
    Standard_Transientoperator= (const Standard_Transient &)
     Assignment operator, needed to avoid copying reference counter.
    virtual ~Standard_Transient ()=default
     Destructor must be virtual.
    virtual const opencascade::handle< Standard_Type > & DynamicType () const
     Returns a type descriptor about this object.
    bool IsInstance (const opencascade::handle< Standard_Type > &theType) const
     Returns a true value if this is an instance of Type.
    bool IsInstance (const char *const theTypeName) const
     Returns a true value if this is an instance of TypeName.
    bool IsKind (const opencascade::handle< Standard_Type > &theType) const
     Returns true if this is an instance of Type or an instance of any class that inherits from Type. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
    bool IsKind (const char *const theTypeName) const
     Returns true if this is an instance of TypeName or an instance of any class that inherits from TypeName. Note that multiple inheritance is not supported by OCCT RTTI mechanism.
    Standard_TransientThis () const
     Returns non-const pointer to this object (like const_cast). For protection against creating handle to objects allocated in stack or call from constructor, it will raise exception Standard_ProgramError if reference counter is zero.
    int GetRefCount () const noexcept
     Get the reference counter of this object.
    void IncrementRefCounter () noexcept
     Increments the reference counter of this object. Uses relaxed memory ordering since incrementing only requires atomicity, not synchronization with other memory operations.
    int DecrementRefCounter () noexcept
     Decrements the reference counter of this object; returns the decremented value. Uses release ordering for the decrement to ensure all writes to the object are visible before the count reaches zero. An acquire fence is added only when the count reaches zero, ensuring proper synchronization before deletion. This is more efficient than using acq_rel for every decrement.
    virtual void Delete () const
     Memory deallocator for transient classes.

    Protected Member Functions

     StepData_FileRecognizer ()
     Assumes that no result has yet been recognized.
    void SetOK (const occ::handle< Standard_Transient > &aresult)
     Records the result of the recognition. Called by specific method Eval to record a result : after calling it, Eval has finished and can return.
    void SetKO ()
     Records that recognition gives no result.
    virtual void Eval (const TCollection_AsciiString &akey)=0
     THIS METHOD DEFINES THE RECOGNITION PROTOCOL, it is proper to each precise type of Recognizer For a suitable type of akey, it calls SetOK(result) where result is an empty result of appropriate type, then returns.

    Additional Inherited Members

    typedef void base_type
     Returns a type descriptor about this object.
    static constexpr const char * get_type_name ()
     Returns a type descriptor about this object.
    static const opencascade::handle< Standard_Type > & get_type_descriptor ()
     Returns type descriptor of Standard_Transient class.

    Constructor & Destructor Documentation

    ◆ StepData_FileRecognizer()

    StepData_FileRecognizer::StepData_FileRecognizer ( )

    Assumes that no result has yet been recognized.

    Member Function Documentation

    ◆ Add()

    void StepData_FileRecognizer::Add ( const occ::handle< StepData_FileRecognizer > & reco)

    Adds a new Recognizer to the Compound, at the end Several calls to Add work by adding in the order of calls : Hence, when Eval has failed to recognize, Evaluate will call Evaluate from the first added Recognizer if there is one, and to the second if there is still no result, and so on.

    ◆ Eval()

    virtual void StepData_FileRecognizer::Eval ( const TCollection_AsciiString & akey)
    protectedpure virtual

    THIS METHOD DEFINES THE RECOGNITION PROTOCOL, it is proper to each precise type of Recognizer For a suitable type of akey, it calls SetOK(result) where result is an empty result of appropriate type, then returns.

    ◆ Evaluate()

    bool StepData_FileRecognizer::Evaluate ( const TCollection_AsciiString & akey,
    occ::handle< Standard_Transient > & res )

    Evaluates if recognition has a result, returns it if yes In case of success, Returns True and puts result in "res" In case of Failure, simply Returns False Works by calling deferred method Eval, and in case of failure, looks for Added Recognizers to work.

    ◆ Result()

    occ::handle< Standard_Transient > StepData_FileRecognizer::Result ( ) const

    Returns result of last recognition (call of Evaluate).

    ◆ SetKO()

    void StepData_FileRecognizer::SetKO ( )
    protected

    Records that recognition gives no result.

    ◆ SetOK()

    void StepData_FileRecognizer::SetOK ( const occ::handle< Standard_Transient > & aresult)
    protected

    Records the result of the recognition. Called by specific method Eval to record a result : after calling it, Eval has finished and can return.
