Detailed Description

Represents a set of uni-directional edges in the column lineage graph, one edge from every source Vertex in 'sources_' to every target Vertex in 'targets_'. An edge indicates a dependency between a source and a target Vertex. There are two types of edges, PROJECTION and PREDICATE, that are described in the ColumnLineageGraph class.
