Michael Dürig updated OAK-781:
------------------------------
Attachment: OAK-781.patch
Attached patch implements the behaviour defined herein and passed all tests.
{{MutableNodeState}} and {{ModifiedNodeState}} contain a flag indicating
whether the state exists or not. This flag is cleared by the node builder when
the base state does not exist and set otherwise. Apart from that these two node
state implementations do not yet correctly implement the {{NodeState}} contract
wrt. existence and iterability.
> Clarify / fix effects of MISSING_NODE as base state of NodeBuilder

> Having a {{MISSING_NODE}} respectively a node state that returns false for
> its {{exists}} method as a base state of a node builder results in undefined
> behaviour. We need to clarify how to handle such cases for resolving OAK-766.
