  • Constructor Details

    • DOTExporter

      public DOTExporter()
      Constructs a new DOTExporter object with an integer name provider for the vertex IDs and null providers for the vertex and edge labels.

    • DOTExporter

      public DOTExporter(VertexNameProvider<V> vertexIDProvider, VertexNameProvider<V> vertexLabelProvider, EdgeNameProvider<E> edgeLabelProvider)
      Constructs a new DOTExporter object with the given ID and label providers.
      Parameters:
      vertexIDProvider - for generating vertex IDs. Must not be null.
      vertexLabelProvider - for generating vertex labels. If null, vertex labels will not be written to the file.
      edgeLabelProvider - for generating edge labels. If null, edge labels will not be written to the file.

    • DOTExporter

      public DOTExporter(VertexNameProvider<V> vertexIDProvider, VertexNameProvider<V> vertexLabelProvider, EdgeNameProvider<E> edgeLabelProvider, ComponentAttributeProvider<V> vertexAttributeProvider, ComponentAttributeProvider<E> edgeAttributeProvider)
      Constructs a new DOTExporter object with the given ID, label, and attribute providers. Note that if a label provider conflicts with a label-supplying attribute provider, the label provider is given precedence.
      Parameters:
      vertexIDProvider - for generating vertex IDs. Must not be null.
      vertexLabelProvider - for generating vertex labels. If null, vertex labels will not be written to the file (unless an attribute provider is supplied which also supplies labels).
      edgeLabelProvider - for generating edge labels. If null, edge labels will not be written to the file.
      vertexAttributeProvider - for generating vertex attributes. If null, vertex attributes will not be written to the file.
      edgeAttributeProvider - for generating edge attributes. If null, edge attributes will not be written to the file.
