◆ 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, draftfunctions.move::move(), 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.

Parameters

obj	reset link property if it is linked to this object
clear	if true, then also reset property if the owner of this property is obj

See also: breakLinks()

Implements App::PropertyLinkBase.

References App::Property::getContainer(), and setValue().

◆ checkRestore()

int PropertyXLinkSubList::checkRestore ( std::string * msg = nullptr ) const

overridevirtual

Test if the link is restored unchanged.

Parameters

msg	optional error message

Reimplemented from 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.

References App::PropertyLinkBase::LinkAllowPartial, PropertyXLinkSubList(), and App::PropertyLinkBase::testFlag().

◆ CopyOnImportExternal()

Property * PropertyXLinkSubList::CopyOnImportExternal ( const std::map< std::string, std::string > & nameMap ) const

overridevirtual

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

Parameters

nameMap a map from the original external object name to the imported new object name

Returns: Returns a copy of the property with the updated link reference if affected. The copy will later be assgiend to this property by calling its Paste().

Reimplemented from App::PropertyLinkBase.

References App::PropertyXLink::copyTo().

◆ CopyOnLabelChange()

Property * PropertyXLinkSubList::CopyOnLabelChange	(	App::DocumentObject *	obj,
		const std::string &	ref,
		const char *	newLabel
	)		const

overridevirtual

Update object label reference in this property.

Parameters

obj	the object owner of the changing label
ref	subname reference to old label
newLabel	the future new label

Returns: Returns a copy of the property if its link reference is affected. The copy will later be assgiend to this property by calling its Paste().

Reimplemented from App::PropertyLinkBase.

References App::PropertyXLink::copyTo().

◆ CopyOnLinkReplace()

Property * PropertyXLinkSubList::CopyOnLinkReplace	(	const App::DocumentObject *	parent,
		App::DocumentObject *	oldObj,
		App::DocumentObject *	newObj
	)		const

overridevirtual

Return a copy of the property if the link replacement affects this property.

Parameters

owner	the parent object whose link property is to be replace. Note that The parent may not be the container of this property. Link sub property can use this opportunity to adjust its relative links.
oldObj	object to be replaced
newObj	object to replace with

Returns: Return a copy of the property that is adjusted for the link replacement operation.

Implements App::PropertyLinkBase.

References App::PropertyXLink::copyTo(), App::PropertyXLink::getSubValues(), and App::PropertyLink::getValue().

◆ getEditorName()

virtual const char * App::PropertyXLinkSubList::getEditorName ( void ) const

overridevirtual

Get the class name of the associated property editor item.

Reimplemented from App::Property.

◆ getLinks()

void PropertyXLinkSubList::getLinks	(	std::vector< App::DocumentObject * > &	objs,
		bool	all = `false`,
		std::vector< std::string > *	subs = `nullptr`,
		bool	newStyle = `true`
	)		const

overridevirtual

Obtain the linked objects.

Parameters

objs	hold the returned linked objects on output
all	if true, then return all the linked object regardless of this LinkScope. If false, then return only if the LinkScope is not hidden.
sub	if given, then return subname references.
newStyle	whether to return new or old style subname reference

Implements App::PropertyLinkBase.

◆ 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

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");

◆ 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.
