class OrphanedNode
Defined at line 22 of file ../../src/sysmem/server/orphaned_node.h
An OrphanedNode keeps the place of a former BufferCollectionToken or BufferCollection in the
hierarchical failure domain tree. This way we don't need to adjust the tree due to disappearing
Node; instead we just replace with an OrphanedNode. The OrphanedNode also preserves the
error_propagation_mode(), and avoids needing to check for Node absence in several places. The
OrphanedNode also preserves BufferCollectionConstraints of a former BufferCollection when
applicable.
The only way an OrphanedNode can exist is if Close() was used on the BufferCollectionToken or
BufferCollection, because otherwise the sub-tree (or whole tree) fails, which removes the nodes
in that sub-tree (or whole tree).
