Standard_Boolean Evaluate (const TCollection_AsciiString &akey, 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. More...
 
Handle< Standard_TransientResult () const
 Returns result of last recognition (call of Evaluate) More...
 
void Add (const 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. More...

Constructor & Destructor Documentation

◆ StepData_FileRecognizer()

StepData_FileRecognizer::StepData_FileRecognizer ( )
protected

Assumes that no result has yet been recognized.

Member Function Documentation

◆ Add()

void StepData_FileRecognizer::Add ( const 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()

Standard_Boolean StepData_FileRecognizer::Evaluate ( const TCollection_AsciiString akey,
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()

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 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.
