@Beta public final class GraphBuilder<N> extends Object
MutableGraph
with userdefined properties.
A graph built by this class will have the following properties by default:
Graph.nodes()
in the order in which the elements were added
Example of use:
MutableGraph<String> graph = GraphBuilder.undirected().allowsSelfLoops(true).build();
graph.putEdge("bread", "bread");
graph.putEdge("chocolate", "peanut butter");
graph.putEdge("peanut butter", "jelly");
Modifier and Type  Method and Description 

GraphBuilder<N> 
allowsSelfLoops(boolean allowsSelfLoops)
Specifies whether the graph will allow selfloops (edges that connect a node to itself).

<N1 extends N> 
build()
Returns an empty
MutableGraph with the properties of this GraphBuilder . 
static GraphBuilder<Object> 
directed()
Returns a
GraphBuilder for building directed graphs. 
GraphBuilder<N> 
expectedNodeCount(int expectedNodeCount)
Specifies the expected number of nodes in the graph.

static <N> GraphBuilder<N> 
from(Graph<N> graph)
Returns a
GraphBuilder initialized with all properties queryable from graph . 
<N1 extends N> 
nodeOrder(ElementOrder<N1> nodeOrder)
Specifies the order of iteration for the elements of
Graph.nodes() . 
static GraphBuilder<Object> 
undirected()
Returns a
GraphBuilder for building undirected graphs.

GraphBuilder
initialized with all properties queryable from graph
.
The "queryable" properties are those that are exposed through the Graph
interface,
such as Graph.isDirected()
. Other properties, such as expectedNodeCount(int)
,
are not set in the new builder.
