Package org.jgrapht.nio.dot

Class DOTImporter<V,​E>

  • Type Parameters:
    V - the graph vertex type
    E - the graph edge type
    All Implemented Interfaces:
    GraphImporter<V,​E>
    public class DOTImporter<V,​E>
extends BaseEventDrivenImporter<V,​E>
implements GraphImporter<V,​E>
    Import a graph from a DOT file.

    For a description of the format see http://en.wikipedia.org/wiki/DOT_language and http://www.graphviz.org/doc/info/lang.html

    The provided graph object, where the imported graph will be stored, must be able to support the features of the graph that is read. For example if the file contains self-loops then the graph provided must also support self-loops. The same for multiple edges. Whether edges are directed or not depends on the underlying implementation of the user provided graph object.

    The graph vertices and edges are build using the corresponding graph suppliers. The id of the vertices in the original dot file are reported as a vertex attribute named "ID". Thus, in case vertices in the dot file also contain an "ID" attribute, such an attribute will be reported multiple times.

                        Reader input)
        Description copied from interface: GraphImporter
        Import a graph using the given Reader.

        It is the callers responsibility to ensure the Reader is closed after this method returned.

        Specified by:
