◆ ReadReal() [2/2]

Standard_Boolean IGESData_ParamReader::ReadReal ( const IGESData_ParamCursor PC,
const Standard_CString  mess,
Standard_Real val 
)

Reads a Real value from parameter "num" An Integer is accepted (Check is filled with a Warning message) and causes return to be True (as normal case) In other cases, Check is filled with a Fail and return is False.

◆ ReadReals() [1/2]

Standard_Boolean IGESData_ParamReader::ReadReals ( const IGESData_ParamCursor PC,
Message_Msg amsg,
Handle< TColStd_HArray1OfReal > &  val,
const Standard_Integer  index = 1 
)

◆ ReadReals() [2/2]

Standard_Boolean IGESData_ParamReader::ReadReals ( const IGESData_ParamCursor PC,
const Standard_CString  mess,
Handle< TColStd_HArray1OfReal > &  val,
const Standard_Integer  index = 1 
)

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.

◆ ReadText() [1/2]

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

◆ ReadText() [2/2]

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.

◆ ReadTexts() [1/2]

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

◆ ReadTexts() [2/2]

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.

◆ ReadXY() [1/2]

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

◆ ReadXY() [2/2]

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.

◆ ReadXYZ() [1/2]

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

◆ ReadXYZ() [2/2]

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.

◆ SendFail()

void IGESData_ParamReader::SendFail ( const Message_Msg amsg)

◆ SendWarning()

void IGESData_ParamReader::SendWarning ( const Message_Msg amsg)

◆ SetCurrentNumber()

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

◆ Stage()

IGESData_ReadStage IGESData_ParamReader::Stage ( ) const

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