Constructor Detail

PathsFinder

public PathsFinder(VertexCondition startSetCondition,
           VertexCondition finalSetCondition,
           boolean shortestPathsOnly)

Creates an instance for the specified vertex conditions.

Parameters:

startSetCondition - Condition defining the start set.

finalSetCondition - Condition defining the final set.

shortestPathsOnly - if true only the shortest paths are returned.

PathsFinder

public PathsFinder(VertexCondition startSetCondition,
           VertexCondition finalSetCondition,
           boolean shortestPathsOnly,
           boolean directPathsOnly)

Creates an instance for the specified vertex conditions.

Parameters:

startSetCondition - Condition defining the start set.

finalSetCondition - Condition defining the final set.

shortestPathsOnly - if true only the shortest paths are returned.

directPathsOnly - if true only paths of length 1 are returned.
