sort

public static <T> boolean sort(Map<T,Set<T>> successors,
 Set<T> visited,
 Set<T> visiting,
 Consumer<T> reversedOrderConsumer,
 T now)

Performs a topological sort recursively through a reverse DFS. The results are passed to the consumer in reverse order, where each element is guaranteed to be passed before any of its predecessors (dependencies). When multiple orders are valid, the results will first trace along earlier returned successors in the successor set iteration for each element.

Parameters:

successors - the map holding information on successor (dependents) of each element

visited - elements that already iterated all their successors

visiting - elements that are still iterating their successors

reversedOrderConsumer - accepts sorted results in reverse order; each element is passed only before any of its predecessors (dependencies) is, or after all its successors (dependents) are passed

now - the starting or current element

Returns:

true if the sort ends up in a loop, or false for a successful sort
