DirectedGraph

class DirectedGraph[T] extends Serializable

Provides useful graph operations for a directed graph.

The node connection in the graph has direction. This class stores a source node. Note that it doesn't maintain the topology. The topology of the graph is stored in the connection of the nodes.

T

Node element type

Instance Constructors

  1. new DirectedGraph(source: Node[T], reverse: Boolean = false)

    source

    source node of the directed graph

    reverse

    use the original direction or the reversed direction

  6. def BFS: Iterator[Node[T]]

    Breadth first search on the graph.

    Breadth first search on the graph. Note that this is a directed BFS. Although eachs node contains both previous and next nodes, only one direction is used.

    returns

    An iterator to go through nodes in the graph in a BFS order

  7. def DFS: Iterator[Node[T]]

    Depth first search on the graph.

    Depth first search on the graph. Note that this is a directed DFS. Although eachs node contains both previous and next nodes, only one direction is used.

    returns

    An iterator to go through nodes in the graph in a DFS order

  10. def cloneGraph(reverseEdge: Boolean = false): DirectedGraph[T]

    Clone the graph structure, will not clone the node element

    Clone the graph structure, will not clone the node element

    reverseEdge

    if reverse the edge in the nodes

    returns

  11. def edges: Int

  21. val reverse: Boolean

    use the original direction or the reversed direction

  22. def size: Int

    How many nodes in the graph

    How many nodes in the graph

    returns

  23. val source: Node[T]
