Other values are considered non valid.

Returns:

difference status

isHierarhyEqual

Shows whether hierarchy of all children, regardless of their properties, are the same for compared and original elements.

Returns:

true if hierarchy of children are the same

isChildrenEqual

boolean isChildrenEqual()

Shows whether hierarchy and properties of all children are the same for compared and original elements.

Returns:

true if hierarchy and properties of children are completely the same
