Method Detail

mine

public HadoopDGraph mine()

Mine a Heuristic Model using the Flexible Heuristics Miner

Returns:

Mined Heuristic Model (null if there is an error)

getDependencyGraph

public HadoopDGraph getDependencyGraph()

Get the dependency graph. If it does not exist, the method computes it.

Returns:

The Dependency Graph
