Detailed Description

access to a list of parameters, with management of read stage (owned parameters, properties, associativities) and current parameter number, read errors (which feed a Check), plus convenient facilities to read parameters, in particular :

first parameter is ignored (it repeats entity type), hence number 1 gives 2nd parameter, etc...
lists are not explicit, list-reading methods are provided which manage a current param. number
interpretation is made as possible (texts, reals, entities ...) (in particular, Reading a Real accepts an Integer)

	)

Reads a list of Real values defined by PC Same conditions as for ReadInts, for PC and index An Integer parameter is accepted, if at least one parameter is Integer, Check is filled with a "Warning" message If all params are neither Real nor Integer, Check is filled (using mess) and return value is False.

Standard_Boolean IGESData_ParamReader::ReadText	(	const IGESData_ParamCursor &	PC,
		const Message_Msg &	amsg,

	)

Standard_Boolean IGESData_ParamReader::ReadText	(	const IGESData_ParamCursor &	PC,
		const Standard_CString	mess,
		Handle< TCollection_HAsciiString > &	val
	)

Reads a Text value from parameter "num", as a String from Collection, that is, Hollerith text without leading "nnnH" If it is not a String, fills Check with a Fail (using mess) and returns False.

Standard_Boolean IGESData_ParamReader::ReadTexts	(	const IGESData_ParamCursor &	PC,
		const Message_Msg &	amsg,
		Handle< Interface_HArray1OfHAsciiString > &	val,
		const Standard_Integer	index = `1`
	)

Standard_Boolean IGESData_ParamReader::ReadTexts	(	const IGESData_ParamCursor &	PC,
		const Standard_CString	mess,
		Handle< Interface_HArray1OfHAsciiString > &	val,
		const Standard_Integer	index = `1`
	)

Reads a list of Hollerith Texts, defined by PC Texts are read as Hollerith texts without leading "nnnH" Same conditions as for ReadInts, for PC and index If all params are not Text, Check is filled (using mess) and return value is False.

Standard_Boolean IGESData_ParamReader::ReadXY	(	const IGESData_ParamCursor &	PC,
		Message_Msg &	amsg,
		gp_XY &	val
	)

Standard_Boolean IGESData_ParamReader::ReadXY	(	const IGESData_ParamCursor &	PC,
		const Standard_CString	mess,
		gp_XY &	val
	)

Reads a couple of Real values (X,Y) from parameter "num" Integers are accepted (Check is filled with a Warning message) and cause return to be True (as normal case) In other cases, Check is filled with a Fail and return is False.

Standard_Boolean IGESData_ParamReader::ReadXYZ	(	const IGESData_ParamCursor &	PC,
		Message_Msg &	amsg,
		gp_XYZ &	val
	)

Standard_Boolean IGESData_ParamReader::ReadXYZ	(	const IGESData_ParamCursor &	PC,
		const Standard_CString	mess,
		gp_XYZ &	val
	)

Reads a triplet of Real values (X,Y,Z) from parameter "num" Integers are accepted (Check is filled with a Warning message) and cause return to be True (as normal case) In other cases, Check is filled with a Fail and return is False For Message.

void IGESData_ParamReader::SendFail ( const Message_Msg & amsg )

void IGESData_ParamReader::SendWarning ( const Message_Msg & amsg )

void IGESData_ParamReader::SetCurrentNumber ( const Standard_Integer num )

sets current parameter number to a new value must be done at end of each step : set on first parameter following last read one; is done by some Read... methods (must be done directly if these method are not used) num greater than NbParams means that following lists are empty If current num is not managed, it remains at 1, which probably will cause error when successive steps of reading are made

IGESData_ReadStage IGESData_ParamReader::Stage ( ) const

gives current stage (Own-Props-Assocs-End, begins at Own)
