java.lang.Objectcom.googlecode.concurrentlinkedhashmap.ConcurrentLinkedHashMap.Builder<K,V>
public static final class ConcurrentLinkedHashMap.Builder<K,V>
A builder that creates ConcurrentLinkedHashMap instances. It
provides a flexible approach for constructing customized instances with
a named parameter syntax. It can be used in the following manner:
ConcurrentMap<Vertex, Set<Edge>> graph = new Builder<Vertex, Set<Edge>>()
.maximumWeightedCapacity(5000)
.weigher(Weighers.<Edge>set())
.build();
