Member Function Documentation

◆ copy()

virtual Geometry * Part::GeomArcOfCircle::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.

◆ getMemSize()

unsigned int GeomArcOfCircle::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::GeomArcOfConic.

◆ getPyObject()

PyObject * GeomArcOfCircle::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::GeomArcOfConic.

◆ getRadius()

◆ getRange()

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

GeomArcOfCircle::getRange.

Parameters
u[out] start angle of the arc, in radians.
v[out] end angle of the arc, in radians.
emulateCCWXYif 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). Additionally, arc's rotation as a whole will be included in the returned u,v (ArcOfCircle specific).

Implements Part::GeomArcOfConic.

◆ Handle()

const Part::GeomArcOfCircle::Handle ( Geom_Geometry  ) const &
virtual

◆ Restore()

void GeomArcOfCircle::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::hasAttribute(), Base::XMLReader::readElement(), and Part::Geometry::Restore().

◆ Save()

void GeomArcOfCircle::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.

◆ setRange()

void GeomArcOfCircle::setRange ( double  u,
double  v,
bool  emulateCCWXY 
)
virtual

GeomArcOfCircle::setRange.

Parameters
u[in] start angle of the arc, in radians.
v[in] end angle of the arc, in radians.
emulateCCWXYif 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). Additionally, arc's rotation as a whole will be subtracted from u,v (ArcOfCircle specific).

◆ toNurbs()

virtual GeomBSplineCurve * Part::GeomArcOfCircle::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.

Reimplemented from Part::GeomCurve.
