Module org.elasticsearch.compute

Package org.elasticsearch.compute.lucene

Class AlwaysReferencedIndexedByShardId

java.lang.Object

org.elasticsearch.compute.lucene.AlwaysReferencedIndexedByShardId

All Implemented Interfaces:

IndexedByShardId<org.elasticsearch.core.RefCounted>

public class AlwaysReferencedIndexedByShardId
extends Object
implements IndexedByShardId<org.elasticsearch.core.RefCounted>

An implementation which always returns RefCounted.ALWAYS_REFERENCED for any shard ID. Used by tests, but defined here so it could also be used by the benchmarks.

Method Summary

Modifier and Type	Method	Description
Collection<? extends org.elasticsearch.core.RefCounted>	collection()	This is not necessarily a list of all values visible via get(int), but rather, a list of the relevant values.
org.elasticsearch.core.RefCounted	get(int shardId)
<S> IndexedByShardId<S>	map(Function<org.elasticsearch.core.RefCounted,S> mapper)	The elements are mapped lazily, i.e., the function would also apply to future elements (as opposed to collection().stream().map, which only maps the current elements).

INSTANCE

public static final AlwaysReferencedIndexedByShardId INSTANCE

Method Details

get

public org.elasticsearch.core.RefCounted get(int shardId)

Specified by:

get in interface IndexedByShardId<org.elasticsearch.core.RefCounted>

collection

public Collection<? extends org.elasticsearch.core.RefCounted> collection()

Description copied from interface: IndexedByShardId

This is not necessarily a list of all values visible via get(int), but rather, a list of the relevant values. This is useful when you need to perform an operation over all relevant values, e.g., closing them.

Specified by:

collection in interface IndexedByShardId<org.elasticsearch.core.RefCounted>

map

public <S> IndexedByShardId<S> map(Function<org.elasticsearch.core.RefCounted,S> mapper)

Description copied from interface: IndexedByShardId

The elements are mapped lazily, i.e., the function would also apply to future elements (as opposed to collection().stream().map, which only maps the current elements).

Specified by:

map in interface IndexedByShardId<org.elasticsearch.core.RefCounted>
