Defines basic File Access Module (Recognize, Read, Write) That is : ReaderModule (Recognize & Read) + Write for StepWriter (for a more centralized description) Warning : A sub-class of ReadWriteModule, which belongs to a particular Protocol, must use the same definition for Case Numbers (give the same Value for a StepType defined as a String from a File as the Protocol does for the corresponding Entity) More...

Standard_Integer CaseNum (const Handle< Interface_FileReaderData > &data, const Standard_Integer num) const override
 Translate the Type of record <num> in <data> to a positive Case Number, or 0 if failed. Works with a StepReaderData, in which the Type of an Entity is defined as a String : Reads the RecordType <num> then calls CaseNum (this type) Warning : The methods CaseStep, StepType and Recognize, must be in phase (triplets CaseNum-StepType-Type of Object) More...
 
virtual Standard_Integer CaseStep (const TCollection_AsciiString &atype) const =0
 Defines Case Numbers corresponding to the recognized Types Called by CaseNum (data,num) above for a Simple Type Entity Warning : CaseStep must give the same Value as Protocol does for the Entity type which corresponds to this Type given as a String. More...

virtual Standard_Boolean IsComplex (const Standard_Integer CN) const
 Returns True if the Case Number corresponds to a Complex Type ("Plex"). Remember that all possible combinations must be aknowledged to be processed Default is False for all cases. For a Protocol which defines possible Plexes, this method must be redefined. More...
 
virtual const TCollection_AsciiStringStepType (const Standard_Integer CN) const =0
 Function specific to STEP, which delivers the StepType as it is recorded in and read from a File compliant with STEP. This method is symmetric to the method CaseStep. StepType can be different from Dynamic Type's name, but belongs to the same class of Object. Returns an empty String if <CN> is zero. Warning : For a Complex Type Entity, returns an Empty String (Complex Type must be managed by users) More...
 
virtual TCollection_AsciiString ShortType (const Standard_Integer CN) const
 Function specific to STEP. Some STEP Types have a short form This method can be redefined to fill it By default, returns an empty string, which is then interpreted to take normal form from StepType. More...
 
virtual Standard_Boolean ComplexType (const Standard_Integer CN, TColStd_SequenceOfAsciiString &types) const
 Function specific to STEP, which delivers the list of types which corresponds to a complex type. If <CN> is not for a complex type, this method returns False. Else it returns True and fills the list in alphabetic order. The default returns False. To be redefined as required. More...

virtual Standard_Boolean NewRead (const Standard_Integer casenum, const Handle< Interface_FileReaderData > &data, const Standard_Integer num, Handle< Interface_Check > &ach, Handle< Standard_Transient > &ent) const
 Specific operator (create+read) defaulted to do nothing. It can be redefined when it is not possible to work in two steps (NewVoid then Read). This occurs when no default constructor is defined : hence the result <ent> must be created with an effective definition from the reader. Remark : if NewRead is defined, Copy has nothing to do.

◆ CaseNum()

Standard_Integer StepData_ReadWriteModule::CaseNum ( const Handle< Interface_FileReaderData > &  data,
const Standard_Integer  num 
) const
overridevirtual

Translate the Type of record <num> in <data> to a positive Case Number, or 0 if failed. Works with a StepReaderData, in which the Type of an Entity is defined as a String : Reads the RecordType <num> then calls CaseNum (this type) Warning : The methods CaseStep, StepType and Recognize, must be in phase (triplets CaseNum-StepType-Type of Object)

Implements Interface_ReaderModule.

◆ CaseStep() [1/2]

virtual Standard_Integer StepData_ReadWriteModule::CaseStep ( const TCollection_AsciiString atype) const
pure virtual

Defines Case Numbers corresponding to the recognized Types Called by CaseNum (data,num) above for a Simple Type Entity Warning : CaseStep must give the same Value as Protocol does for the Entity type which corresponds to this Type given as a String.

◆ IsComplex()

virtual Standard_Boolean StepData_ReadWriteModule::IsComplex ( const Standard_Integer  CN) const

virtual

Function specific to STEP. Some STEP Types have a short form This method can be redefined to fill it By default, returns an empty string, which is then interpreted to take normal form from StepType.

◆ StepType()

virtual const TCollection_AsciiString& StepData_ReadWriteModule::StepType ( const Standard_Integer  CN) const
