java.lang.Object

org.apache.solr.common.cloud.ZkNodeProps

org.apache.solr.common.cloud.Slice

所有已实现的接口:

Iterable<Replica>, JSONWriter.Writable

public class Slice
extends ZkNodeProps
implements Iterable<Replica>

A Slice contains immutable information about a logical shard (all replicas that share the same shard id).

构造器详细资料

Slice

public Slice(String name,
             Map<String,Replica> replicas,
             Map<String,Object> props,
             String collection)

参数:

name - The name of the slice

replicas - The replicas of the slice. This is used directly and a copy is not made. If null, replicas will be constructed from props.

props - The properties of the slice - a shallow copy will always be made.

方法详细资料

loadAllFromMap

public static Map<String,Slice> loadAllFromMap(String collection,
                                               Map<String,Object> genericSlices)

Loads multiple slices into a Map from a generic Map that probably came from deserialized JSON.
