Detailed Description

UUID properties This property handles unique identifieers.

Constructor & Destructor Documentation

◆ PropertyUUID()

PropertyUUID::PropertyUUID ( void  )

A constructor.

A more elaborate description of the constructor.

◆ ~PropertyUUID()

PropertyUUID::~PropertyUUID ( )
virtual

A destructor.

A more elaborate description of the destructor.

Member Function Documentation

◆ Copy()

Property * PropertyUUID::Copy ( void  ) const
virtual

Returns a new copy of the property (mainly for Undo/Redo and transactions)

Implements App::Property.

◆ getMemSize()

unsigned int PropertyUUID::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? This method is defined in Base::Persistence.

See also
Base::Persistence

Reimplemented from App::Property.

◆ getPyObject()

PyObject * PropertyUUID::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'.

Reimplemented from Base::BaseClass.

◆ getValue()

const Base::Uuid & PropertyUUID::getValue ( void  ) const

◆ getValueStr()

const std::string & PropertyUUID::getValueStr ( void  ) const

◆ Paste()

void PropertyUUID::Paste ( const Property from)
virtual

Paste the value from the property (mainly for Undo/Redo and transactions)

Implements App::Property.

◆ Restore()

void PropertyUUID::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:

{
// 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");
}

Definition: Reader.cpp:240
double getAttributeAsFloat(const char *AttrName) const
return the named attribute as a double floating point (does type checking)
Definition: Reader.cpp:158

Implements Base::Persistence.

References Base::XMLReader::getAttribute(), and Base::XMLReader::readElement().

◆ Save()

void PropertyUUID::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;
}
virtual void Save(Base::Writer &writer) const override
This method is used to save properties to an XML document.
Definition: PropertyGeo.cpp:165

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.

◆ setPyObject()

void PropertyUUID::setPyObject ( PyObject value)
virtual

Reimplemented from Base::BaseClass.

◆ setValue() [1/3]

void PropertyUUID::setValue ( const Base::Uuid id)

◆ setValue() [2/3]

void PropertyUUID::setValue ( const char *  sString)

◆ setValue() [3/3]

void PropertyUUID::setValue ( const std::string &  sString)
