示例1: copyOf
import com.google.common.graph.GraphConstants.Presence; //导入依赖的package包/类
/** Returns an immutable copy of {@code graph}. */
public static <N> ImmutableGraph<N> copyOf(Graph<N> graph) {
return (graph instanceof ImmutableGraph)
? (ImmutableGraph<N>) graph
: new ImmutableGraph<N>(new ConfigurableValueGraph<N, Presence>(
GraphBuilder.from(graph), getNodeConnections(graph), graph.edges().size()));
}
示例2: getNodeConnections
import com.google.common.graph.GraphConstants.Presence; //导入依赖的package包/类
private static <N> ImmutableMap<N, GraphConnections<N, Presence>> getNodeConnections(
Graph<N> graph) {
// ImmutableMap.Builder maintains the order of the elements as inserted, so the map will have
// whatever ordering the graph's nodes do, so ImmutableSortedMap is unnecessary even if the
// input nodes are sorted.
ImmutableMap.Builder<N, GraphConnections<N, Presence>> nodeConnections = ImmutableMap.builder();
for (N node : graph.nodes()) {
nodeConnections.put(node, connectionsOf(graph, node));
}
