Class Connection<V>

java.lang.Object

com.github.yellowstonegames.path.Edge<V>

com.github.yellowstonegames.path.Connection<V>

Type Parameters:

V - the vertex type; often Coord

Direct Known Subclasses:

Connection.DirectedConnection, Connection.UndirectedConnection

public abstract class Connection<V>
extends Edge<V>

The most-commonly-used class that represents an edge between nodes on a Graph. Different kinds of graph will use different subclasses of this to represent their edges: Connection.DirectedConnection or Connection.UndirectedConnection. These subclasses don't add new functionality, but they compare differently during hashing and equality checks.
