Description
Traverses the hierarchy in pre-order (root first, then its children), starting at an optional parent object.
Example sequence of callback invocations:
(/Game/Maps.Map, /Game/Maps.Map:PersistentLevel)
(/Game/Maps.Map:PersistentLevel, /Game/Maps.Map:PersistentLevel.Cube)
(/Game/Maps.Map:PersistentLevel.Cube, /Game/Maps.Map:PersistentLevel.Cube.StaticMeshComponent0)
(/Game/Maps.Map:PersistentLevel.Cube, /Game/Maps.Map:PersistentLevel.Cube.StaticMeshComponent1)
(/Game/Maps.Map:PersistentLevel, /Game/Maps.Map:PersistentLevel.Sphere)
(/Game/Maps.Map:PersistentLevel.Sphere, /Game/Maps.Map:PersistentLevel.Sphere.StaticMeshComponent0)
This lists implicit parents. For example, if you called AddObject(/Game/Maps.Map:PersistentLevel.Cube.StaticMeshComponent0), then its outers will be implicitly considered part of the hierarchy (i.e. /Game/Maps.Map:PersistentLevel.Cube, /Game/Maps.Map:PersistentLevel, /Game/Maps.Map). Use the FChildRelation to determine whether an object is part of the hiearchy implicitly or explicitly. Assets without subobjects are not listed. For example, if you called AddObject(/Game/Maps.Map) and the hierarchy was otherwise empty, Callback would not be invoked.
