StepData

# StepData_ReadWriteModule Class Reference

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)
.

## Public Member Functions
Standard_EXPORT Standard_Integer | CaseNum (const Handle(Interface_FileReaderData)&data, const Standard_Integer num) const
| 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) .
virtual Standard_EXPORT 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 .
virtual Standard_EXPORT Standard_Integer | CaseStep (const TColStd_SequenceOfAsciiString &types) const
| Same a above but for a Complex Type Entity ("Plex") The provided Default recognizes nothing .
virtual Standard_EXPORT 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. .
virtual Standard_EXPORT const TCollection_AsciiString & | StepType (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) .
virtual Standard_EXPORT 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 .
virtual Standard_EXPORT 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. .
Standard_EXPORT void | Read (const Standard_Integer CN, const Handle(Interface_FileReaderData)&data, const Standard_Integer num, Handle(Interface_Check)&ach, const Handle(Standard_Transient)&ent) const
| General Read Function, calls ReadStep .
virtual Standard_EXPORT void | ReadStep (const Standard_Integer CN, const Handle(StepData_StepReaderData)&data, const Standard_Integer num, Handle(Interface_Check)&ach, const Handle(Standard_Transient)&ent) const =0
| Specific Read Function. Works with StepReaderData .
virtual Standard_EXPORT void | WriteStep (const Standard_Integer CN, StepData_StepWriter &SW, const Handle(Standard_Transient)&ent) const =0
| Write Function, switched by CaseNum .
Standard_EXPORT const | Handle (Standard_Type)&DynamicType() const
