-- File: HLRBRep_LineTool.cdl -- Created: Wed Aug 18 14:58:10 1993 -- Author: Christophe MARION -- ---Copyright: Matra Datavision 1993 class LineTool from HLRBRep ---Purpose: The LineTool class provides class methods to -- access the methodes of the Line. uses Shape from GeomAbs, CurveType from GeomAbs, Vec from gp, Pnt from gp, Circ from gp, Elips from gp, Hypr from gp, Parab from gp, Lin from gp, BezierCurve from Geom, BSplineCurve from Geom, Array1OfPnt from TColgp, Array1OfReal from TColStd, HArray1OfReal from TColStd, Array1OfInteger from TColStd raises OutOfRange from Standard, NoSuchObject from Standard, DomainError from Standard is -- -- Global methods - Apply to the whole Line. -- FirstParameter(myclass; C : Lin from gp) returns Real ---C++: inline ; LastParameter(myclass; C : Lin from gp) returns Real ---C++: inline ; Continuity(myclass; C : Lin from gp) returns Shape from GeomAbs ---C++: inline ; NbIntervals(myclass; C : Lin from gp; S : Shape from GeomAbs) returns Integer ---Purpose: If necessary, breaks the line in intervals of -- continuity . And returns the number of -- intervals. ---C++: inline ; Intervals(myclass; C :Lin from gp; T: out Array1OfReal from TColStd; Sh : Shape from GeomAbs) ---Purpose: Sets the current working interval. raises OutOfRange from Standard -- if Index < 1 or Index > NbIntervals ---C++: inline ; -- -- Local methods - Apply to the current interval. -- By default the current interval is the first. -- IntervalFirst(myclass; C : Lin from gp) returns Real ---Purpose: Returns the first parameter of the current -- interval. ---C++: inline ; IntervalLast(myclass; C : Lin from gp) returns Real ---Purpose: Returns the last parameter of the current -- interval. ---C++: inline ; IntervalContinuity(myclass; C : Lin from gp) returns Shape from GeomAbs ---C++: inline ; IsClosed(myclass; C : Lin from gp) returns Boolean ---C++: inline ; IsPeriodic(myclass; C : Lin from gp) returns Boolean ---C++: inline ; Period(myclass; C : Lin from gp) returns Real raises DomainError from Standard -- if the line is not periodic ---C++: inline ; Value(myclass; C : Lin from gp; U : Real) returns Pnt from gp --- Purpose : Computes the point of parameter U on the line. ---C++: inline ; D0 (myclass; C : Lin from gp; U : Real; P : out Pnt from gp) --- Purpose : Computes the point of parameter U on the line. ---C++: inline ; D1 (myclass; C : Lin from gp; U : Real; P : out Pnt from gp ; V : out Vec from gp) --- Purpose : Computes the point of parameter U on the line with its -- first derivative. raises DomainError from Standard --- Purpose : Raised if the continuity of the current interval -- is not C1. ---C++: inline ; D2 (myclass; C : Lin from gp; U : Real; P : out Pnt from gp; V1, V2 : out Vec from gp) --- Purpose : -- Returns the point P of parameter U, the first and second -- derivatives V1 and V2. raises DomainError from Standard --- Purpose : Raised if the continuity of the current interval -- is not C2. ---C++: inline ; D3 (myclass; C : Lin from gp; U : Real; P : out Pnt from gp; V1, V2, V3 : out Vec from gp) --- Purpose : -- Returns the point P of parameter U, the first, the second -- and the third derivative. raises DomainError from Standard --- Purpose : Raised if the continuity of the current interval -- is not C3. ---C++: inline ; DN (myclass; C : Lin from gp; U : Real; N : Integer) returns Vec from gp --- Purpose : -- The returned vector gives the value of the derivative for the -- order of derivation N. raises DomainError from Standard, --- Purpose : Raised if the continuity of the current interval -- is not CN.
