◆ Restore()

void Trajectory::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");
}

Implements Base::Persistence.

References generateTrajectory(), Base::XMLReader::getAttributeAsInteger(), Base::XMLReader::readElement(), Robot::Waypoint::Restore(), and vpcWaypoints.

Referenced by Robot::PropertyTrajectory::Restore().

◆ Save()

void Trajectory::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.
