PyObject * PropertyInteger::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'.

void PropertyInteger::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 = (float)reader.getAttributeAsFloat("valueX");
   _cVec.y = (float)reader.getAttributeAsFloat("valueY");
   _cVec.z = (float)reader.getAttributeAsFloat("valueZ");
 }

Implements Base::Persistence.

Reimplemented in App::PropertyEnumeration.

Definition at line 110 of file PropertyStandard.cpp.

References Base::XMLReader::getAttributeAsInteger(), Base::XMLReader::readElement(), and setValue().

void PropertyInteger::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 indention, 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.
