Returns an iterable of the values starting with the first node which is equal according to reference and consisting of all values equal or larger with respect to reference.
Returns an iterable of the values starting with the first node which is equal according to reference and consisting of all values equal or larger with respect to reference.
reference is either a value of type T or a function
int order(T treevalue) which returns -1, 0, or 1 depending on
wether the value treevalue of a tree node is smaller, equal,
or larger as the reference point.
The standard case is to invoke it with a value of type T. The second option is useful in special usage scenarios only, see notes in the class description.
If this tree supports equivalence classes, it returns
an Iterable of ListT, otherwise an Iterable
of T.
Retuns an empty Iterable if there is no such equivalence class.
