|
|
|
---Purpose: deferred class describing a continous 2d function f(u)
|
|
|
|
|
|
uses Pnt2d from gp,
|
|
Vec2d from gp
|
|
|
|
is

Delete(me:out) is virtual;
|
|
---C++: alias "Standard_EXPORT virtual ~AppCont_Function2d(){Delete() ; }"
|
|
|
|
|
|
FirstParameter(me) returns Real
|
|
---Purpose: returns the first parameter of the function.
|
|
is deferred;
|
|
|
|
LastParameter(me) returns Real
|
|
---Purpose: returns the last parameter of the function.

Value(me; U: Real) returns Pnt2d
|
|
---Purpose: returns the point at parameter <U>.
|
|
is deferred;
|
|
|
|
D1(me; U: Real; P: in out Pnt2d; V: in out Vec2d) returns Boolean
