所有已实现的接口:

ReplicaListTransformer

public class AffinityReplicaListTransformer
extends Object
implements ReplicaListTransformer

Allows better caching by establishing deterministic evenly-distributed replica routing preferences according to either explicitly configured hash routing parameter, or the hash of a query parameter (configurable, usually related to the main query).

getInstance

public static ReplicaListTransformer getInstance(String dividendParam,
                                                 String hashParam,
                                                 SolrParams requestParams)

参数:

dividendParam - int param to be used directly for mod-based routing

hashParam - String param to be hashed into an int for mod-based routing

requestParams - the parameters of the Solr request

返回:

null if specified routing vals are not able to be parsed properly

transform

public void transform(List<?> choices)

从接口复制的说明: ReplicaListTransformer

Transforms the passed in list of choices. Transformations can include (but are not limited to) reordering of elements (e.g. via shuffling) and removal of elements (i.e. filtering).

指定者:

transform 在接口中 ReplicaListTransformer

参数:

choices - - a list of choices to transform, typically the choices are Replica objects but choices can also be String objects such as URLs passed in via the ShardParams.SHARDS parameter.
