Type	Name	Description
bool	AreMatching ( const InNodeType& TreeNodeA, const InNodeType& TreeNodeB, TArray< FPropertySoftPath >* OutDifferingProperties )	Determine whether two nodes occupy the same space in their trees for example if you have a tree key/value pairs, AreMatching should compare the keys while AreValuesEqual should compare the values
bool	AreValuesEqual ( const InNodeType& TreeNodeA, const InNodeType& TreeNodeB, TArray< FPropertySoftPath >* OutDifferingProperties )	Determine whether the values stored in two nodes are equal.
void	GetChildren ( const InNodeType& InParent, TArray< InNodeType >& OutChildren )	Retrieves an array of children nodes from the parent node
bool	ShouldInheritEqualFromChildren ( const InNodeType& TreeNodeA, const InNodeType& TreeNodeB )	Return true if TreeNode is considered equal when all it's children are equal.
bool	ShouldMatchByValue ( const InNodeType& TreeNode )	Return true for nodes that match using AreValuesEqual first, and pair up by position second this is useful for arrays since we often want to keep elements with the same data paired while diffing other elements in order
