◆ copy()

virtual Geometry * Part::GeomArcOfEllipse::copy ( void ) const

virtual

returns a copy of this object having a new randomly generated tag.

If you also want to copy the tag, you may use clone() instead. For creation of geometry with other handles, with or without the same tag, you may use the constructors and the sethandle functions. The tag of a geometry can be copied to another geometry using the assignTag function.

Implements Part::GeomArcOfConic.

◆ getMajorAxisDir()

Base::Vector3d GeomArcOfEllipse::getMajorAxisDir ( ) const

GeomArcOfEllipse::getMajorAxisDir.

Returns: the direction vector (unit-length) of major axis of the ellipse. The direction also points to the first focus.

◆ getPyObject()

PyObject * GeomArcOfEllipse::getPyObject ( void )

virtual

This method returns the Python wrapper for a C++ object.

It's in the responsibility of the programmer to do the correct reference counting. Basically there are two ways how to implement that: Either always return a new Python object then reference counting is not a matter or return always the same Python object then the reference counter must be incremented by one. However, it's absolutely forbidden to return always the same Python object without incrementing the reference counter.

The default implementation returns 'None'.

◆ getRange()

void GeomArcOfEllipse::getRange	(	double &	u,
		double &	v,
		bool	emulateCCWXY
	)		const

virtual

GeomArcOfEllipse::getRange.

Parameters

u	[out] start angle of the arc, in radians.
v	[out] end angle of the arc, in radians.
emulateCCWXY	if true, the arc will pretent to be a CCW arc in XY plane. For this to work, the arc must lie in XY plane (i.e. Axis is either +Z or -Z).

◆ Handle()

const Part::GeomArcOfEllipse::Handle ( Geom_Geometry ) const &

virtual

Implements Part::GeomArcOfConic.

Referenced by getMajorAxisDir(), getMinorRadius(), Restore(), Save(), setHandle(), setMajorAxisDir(), and setMinorRadius().

◆ Restore()

void GeomArcOfEllipse::Restore ( Base::XMLReader & )

virtual

This method is used to restore properties from an XML document.

It uses the XMLReader class, which bases on SAX, to read the in Save() written information. Again the Vector as an example:

void PropertyVector::Restore(Base::XMLReader &reader)
{
  // read my Element
  reader.readElement("PropertyVector");
  // get the value of my Attribute
  _cVec.x = reader.getAttributeAsFloat("valueX");
  _cVec.y = reader.getAttributeAsFloat("valueY");
  _cVec.z = reader.getAttributeAsFloat("valueZ");
}

Reimplemented from Part::GeomTrimmedCurve.

References Base::XMLReader::getAttributeAsFloat(), Handle(), Base::XMLReader::readElement(), and Part::Geometry::Restore().

◆ Save()

void GeomArcOfEllipse::Save ( Base::Writer & ) const

virtual

This method is used to save properties to an XML document.

A good example you'll find in PropertyStandard.cpp, e.g. the vector:

void PropertyVector::Save (Writer &writer) const
{
   writer << writer.ind() << "<PropertyVector valueX=\"" <<  _cVec.x <<
                                          "\" valueY=\"" <<  _cVec.y <<
                                          "\" valueZ=\"" <<  _cVec.z <<"\"/>" << endl;
}

The writer.ind() expression writes the indentation, just for pretty printing of the XML. As you see, the writing of the XML document is not done with a DOM implementation because of performance reasons. Therefore the programmer has to take care that a valid XML document is written. This means closing tags and writing UTF-8.

◆ setMajorAxisDir()

void GeomArcOfEllipse::setMajorAxisDir ( Base::Vector3d newdir )

GeomArcOfEllipse::setMajorAxisDir Rotates the ellipse in its plane, so that its major axis is as close as possible to the provided direction.

Parameters

newdir [in] is the new direction. If the vector is small, the orientation of the ellipse will be preserved. If the vector is not small, but its projection onto plane of the ellipse is small, an exception will be thrown.

Parameters

v	[in] end angle of the arc, in radians.
emulateCCWXY	if true, the arc will pretent to be a CCW arc in XY plane. For this to work, the arc must lie in XY plane (i.e. Axis is either +Z or -Z).

◆ toNurbs()

virtual GeomBSplineCurve * Part::GeomArcOfEllipse::toNurbs	(	double	first,
		double	last
	)		const

virtual

The default implementation does the same as toBSpline. In sub-classes this can be reimplemented to create a real NURBS curve and not just an approximation.
