All Implemented Interfaces:

Streamable<Fragment>, Iterable<Fragment>

public abstract class EquivalentFragmentSet
extends Object
implements Streamable<Fragment>

a pattern to match in the graph. comprised of Fragments, each describing one way to represent the traversal, starting from different variables.
