ModifyNodeViaNativeCounterpart()

void xiiAbstractObjectGraph::ModifyNodeViaNativeCounterpart	(	xiiAbstractObjectNode *	pRootNode,
		xiiDelegate< void(void *, const xiiRTTI *)>	callback )

Allows for a given node to be modified as a native object. Once the callback exits any changes to the sub-hierarchy of the given root node will be written back to the node objects.

ReMapNodeGuids()

void xiiAbstractObjectGraph::ReMapNodeGuids	(	const xiiUuid &	seedGuid,
		bool	bRemapInverse = false )

Remaps all node guids by adding the given seed, or if bRemapInverse is true, by subtracting it/ This is mostly used to remap prefab instance graphs to their prefab template graph.

ReMapNodeGuidsToMatchGraph()

void xiiAbstractObjectGraph::ReMapNodeGuidsToMatchGraph	(	xiiAbstractObjectNode *	pRoot,
		const xiiAbstractObjectGraph &	rhsGraph,
		const xiiAbstractObjectNode *	pRhsRoot )

Tries to remap the guids of this graph to those in rhsGraph by walking in both down the hierarchy, starting at root and rhsRoot.

Note that in case of array properties the remapping assumes element indices to be equal on both sides which will cause all moves inside the arrays to be lost as there is no way of recovering this information without an equality criteria. This function is mostly used to remap a graph from a native object to a graph from xiiDocumentObjects to allow applying native side changes to the original xiiDocumentObject hierarchy using diffs.
