Introduction

The GEF4 Graph component provides a simple, UI-independent graph model. It consists of the single Graph module.

Graph

  • feature: org.eclipse.gef4.graph
  • bundle: org.eclipse.gef4.graph

The Graph module of the GEF4 Graph component only provides the single {Root} package.


{Root}

  • package: org.eclipse.gef4.graph

This package provides a simple graph model and a support class to copy/merge such models.

Graph, Node, Edge

A Graph serves as a container for Nodes and Edges. Additionally, a Graph can be nested inside a nesting Node, so that sub-graphs can be properly represented.

Moreover, arbitrary attributes can be set on Graphs, Nodes, and Edges. The concrete attributes that are used are outside the scope of the GEF Graph component. The DOT importer of the GEF DOT component, e.g. adds DOT-specific attributes to the Graph it creates, the GEF Zest component uses visualization-specific attributes, which determine the concrete visualization.

GraphCopier

The graph package also contains a utility class (GraphCopier) to copy/merge graphs.
