Called before a child property changing value.

Reimplemented from App::Property.

◆ addValue() [1/2]

◆ adjustLink()

bool PropertyXLinkSubList::adjustLink ( const std::set< App::DocumentObject * > & inList )

overridevirtual

Called to adjust the link to avoid potential cyclic dependency.

Parameters

inList recursive in-list of the would-be parent

Returns: Return whether the link has been adjusted

This function tries to correct the link to avoid any (sub)object inside in-list. If the adjustment is impossible, exception will be raised

Implements App::PropertyLinkBase.

References App::Hidden, and setValues().

◆ afterRestore()

void PropertyXLinkSubList::afterRestore ( )

overridevirtual

Called at the beginning of Document::afterRestore()

This function is called without dependency sorting, because some types of link property can only reconstructs the linking information inside this function.

One example use case of this function is PropertyLinkSub that uses afterRestore() to parse and restore subname references, which may contain sub-object reference from external document, and there will be special mapping required during object import.

Another example is PropertyExpressionEngine which only parse the restored expression in afterRestore(). The reason, in addition to subname mapping like PropertyLinkSub, is that it can handle document name adjustment as well. It internally relies on PropertyXLink to store the external document path for external linking. When the external document is restored, its internal name may change due to name conflict with existing documents. PropertyExpressionEngine can now auto adjust external references without any problem.

Reimplemented from App::Property.

◆ breakLink()

void PropertyXLinkSubList::breakLink	(	App::DocumentObject *	obj,
		bool	clear
	)

overridevirtual

Called to reset this link property.

See also: breakLinks()

Implements App::PropertyLinkBase.

◆ Copy()

Property * PropertyXLinkSubList::Copy ( void ) const

overridevirtual

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

Implements App::Property.

overridevirtual

Return a copy of the property if any changes caused by importing external linked object.

Parameters

Update object label reference in this property.

Parameters

Reimplemented from App::Property.

	)		const

overridevirtual

◆ getMemSize()

unsigned int PropertyXLinkSubList::getMemSize ( void ) const

overridevirtual

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 * PropertyXLinkSubList::getPyObject ( void )

overridevirtual

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'.

◆ onContainerRestored()

void PropertyXLinkSubList::onContainerRestored ( )

overridevirtual

Called before calling DocumentObject::onDocumentRestored()

This function is called after finished calling Property::afterRestore() of all properties of objects. By then, the object dependency information is assumed ready. So, unlike Property::afterRestore(), this function is called on objects with dependency order.

Reimplemented from App::Property.

◆ Paste()

void PropertyXLinkSubList::Paste ( const Property & from )

overridevirtual

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

Implements App::Property.

◆ referenceChanged()

overridevirtual

Test if the element reference has changed after restore.

Reimplemented from App::PropertyLinkBase.

◆ removeValue()

int PropertyXLinkSubList::removeValue ( App::DocumentObject * lValue )

Removes all occurrences of lValue in the property together with its sub-elements and returns the number of entries removed.

◆ Restore()

void PropertyXLinkSubList::Restore ( Base::XMLReader & )

overridevirtual

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 Base::XMLReader::getAttributeAsInteger(), Base::XMLReader::hasAttribute(), App::PropertyLinkBase::LinkAllowPartial, Base::XMLReader::readElement(), Base::XMLReader::readEndElement(), and App::PropertyLinkBase::setFlag().

◆ Save()

void PropertyXLinkSubList::Save ( Base::Writer & ) const

overridevirtual

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.
