All Implemented Interfaces:

Serializable

@Beta
public final class Mutation
extends Object
implements Serializable

The Mutation class represents a collection of relations which can be used to generate lineage for a directive. It uses a UUID so that the name will be unique.

As this class is immutable, the constructor requires all the member variables to be presented for an instance of this object to be created.

The class has methods to retrieve the readable text describing the transformation, and relations to retrieve all the associations of source to targets
