Fusion

Gradoop Integration for KNIME Workbench version 1.0.0.v201911212144 by Steffen Dienst

Fusion is a binary operator taking two graphs: a search graph (first parameter) and a pattern graph (second parameter) [This means that this is not a symmetric operator (F(a,b) != F(b,a))]. The general idea of this operator is that everything that appears in the pattern graph is fused into a single vertex into the search graph. A new logical graph is returned.

  1. If any search graph is empty, an empty result will always be returned
  2. If a pattern graph is empty, then the search graph will always be returned
  3. The vertices of the pattern graph appearing in the first parameter are replaced by a new vertex. The old edges of the search graph are updated in the final result so that each vertex, either pointing to a to-be-fused vertex or starting from a to-be-fused vertex, are respectively updated as either pointing or starting from the fused vertex.
  4. Pattern graph's edges are also taken into account: any edge between to-be-fused vertices appearing in the search graph that are not expressed in the pattern graph are rendered as hooks over the fused vertex
