Package org.jgrapht.io

Class JSONExporter<V,E>

java.lang.Object

org.jgrapht.io.JSONExporter<V,E>

Type Parameters:

V - the graph vertex type

E - the graph edge type

All Implemented Interfaces:

GraphExporter<V,E>

@Deprecated
public class JSONExporter<V,E>
extends Object
implements GraphExporter<V,E>

Deprecated.

Use JSONExporter instead.

Exports a graph using JSON.

The output is one object which contains:

• A member named nodes whose value is an array of nodes.
• A member named edges whose value is an array of edges.
• Two members named creator and version for metadata.

Each node contains an identifier and possibly other attributes provided using a ComponentAttributeProvider. Similarly each edge contains the source and target vertices, a possible identifier using ComponentNameProvider and possible other attributes using a ComponentAttributeProvider. All these can be adjusted using the appropriate constructor call, see JSONExporter(ComponentNameProvider, ComponentAttributeProvider, ComponentNameProvider, ComponentAttributeProvider). The default constructor constructs integer identifiers using an IntegerComponentNameProvider for both vertices and edges and does not output any custom attributes using EmptyComponentAttributeProvider.
