Constructor Detail

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.
