No longer add dynamic property for alias, simply rely on
get(Dynamic)PropertyByName() to check for aliases.
Add new API PropertyContainer::getPropertyNamedList() so that
ExpressionCompleter can discover properties with aliases.
Property:
* Extended property status bitset. Mirror most of PropertyType and
allow dynamic change property type.
* Cache property name and type to improve performance
* Centralize property status change signalling
* Change aboutToSetValue()/hasSetValue() to virtual
* Add new API getFullName() to obtain full quanlified name of the property
AtomicPropertyChangeInterface:
* Allow calling aboutToSetValue()/hasSetValue() when actually changed
PropertyLists:
* Refactor implementation by an abstract class PropertyListBase and a
template class PropertyListsT, to allow better code reuse.
PropertyListT is derived from AtomicPropertyChangeInterface to allow
more efficient change on individual elements.
* All list type property now accept setting python value as a dictionary
with index as key to set individual element of a list.
* Add touch list for more efficient handling of value changes. The list
contains the index of changed value. And empty touch list should be
treated as the entire list is changed. PropertyContainerPy expose this
functionality with getPropertyTouchList().
PropertyPersistentObject:
* New property to allow dynamic creation of any FreeCAD object derived
from Base::Persistence, and use it as a property.
DynamicProperty:
* Use boost multi_index_container for efficient property lookup while
keeping order.
* Modify to be allowed to use in PropertyContainer directly
PropertyContainer:
* Use boost multi_index_container for efficient property lookup while
keeping order.
* Allow adding/removing dynamic property on all property container
* Modify Save/Restore() to persist property status, and better handle
transient property which can now be dynamically enabled/disabled per
object.
* Add new API getFullName() to obtain full quanlified name of the property.
Implemented by Document, DocumentObject, and also
ViewProviderDocumentObject if future patch
DocumentObject and FeaturePython are modified to accommondate the
dynamic property changes.
Removed get/setCustomAttribute() implementation from DocumentObjectPy,
and rely on PropertyContainerPy for the implementation, because of the
additional dynamic property support in property container.
Gui::ViewProviderDocumentObject, which is derived from
PropertyContainer, is also modified accordingly
At the moment many feature classes lack of the mustExecute() method and thus can cause a touched feature not to be recomputed and causes the feature to be in a broken state.
Now this new enum value virtually makes the mustExecute() superfluous and thus guarantees to recompute a feature if a modified property has not set the Prop_NoRecompute flag.
On the other hand there are properties that should only touch a feature but not enforce a recompute. This guarantees a better performance and avoids unnecessary recomputes.
For example this is useful for placements where a change can be applied on-the-fly and the feature is up-to-date. Other features that depend on the touched feature will still be recomputed.
