GraphCrawler<T extends Object> class Null safety

Utility class for crawling a graph defined by edges and retrieving paths and walks.

  • A directed path is defined as a list of connected vertices where each inner vertex is listed at most once. The first and the last vertex may be same in order to represent a cycle.
  • A directed walk is defined as a list of connected vertices that can be traversed in sequential order.
