Certainly, if you have a function

function Size (Tree : Tree_Type_Name) return Natural;

that returns the number of elements in Tree, you can declare something
like

type Tree_As_Array is array (Positive range <>) of
Tree_Element_Type_Name;

and then declare an array of the right size for a specific tree

Flat : Tree_As_Array (1 .. Size (Tree) );

and then somehow extract the elements of Tree into the components of
Flat.

I'm not sure if this answers your question or not.
