Known Subclasses:

featurechart.FeatureCompleterRule

A rule that joins a given complete edge with adjacent incomplete edges in the chart, to form combined edges. In particular, this rule specifies that:

[B→γ*][j:k]

licenses the edge:

[A→αB*β][i:j]

given that the chart contains:

[A→α*Bβ][i:j]

Note: This is basically FundamentalRule, with the left edge left unspecified.
