returns a cloned object

◆ getMajorAxisDir()

Base::Vector2d Geom2dEllipse::getMajorAxisDir ( ) const

Geom2dEllipse::getMajorAxisDir.

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

double Part::Geom2dEllipse::getMajorRadius ( void ) const

◆ getMemSize()

unsigned int Geom2dEllipse::getMemSize ( void ) const

virtual

This method is used to get the size of objects It is not meant to have the exact size, it is more or less an estimation which runs fast! Is it two bytes or a GB?

Implements Part::Geom2dConic.

◆ getMinorRadius()

double Geom2dEllipse::getMinorRadius ( void ) const

References Handle().

◆ getPyObject()

PyObject * Geom2dEllipse::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'.

Implements Part::Geom2dConic.

◆ Handle()

const Part::Geom2dEllipse::Handle ( Geom2d_Geometry ) const &

virtual

Implements Part::Geom2dConic.

Referenced by Geom2dEllipse(), getMinorRadius(), setHandle(), and setMinorRadius().

◆ Restore()

void Geom2dEllipse::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::Geometry2d.

References Base::XMLReader::getAttributeAsFloat(), Base::XMLReader::readElement(), Part::Geometry2d::Restore(), and Part::Geom2dConic::RestoreAxis().

◆ Save()

void Geom2dEllipse::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.

◆ setHandle()

References Handle().

◆ setMajorAxisDir()

void Geom2dEllipse::setMajorAxisDir ( Base::Vector2d newdir )

Geom2dEllipse::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.
