Package org.apache.solr.core

Class SyntheticSolrCore

java.lang.Object

org.apache.solr.core.SolrCore

org.apache.solr.core.SyntheticSolrCore

All Implemented Interfaces:

Closeable, AutoCloseable, SolrInfoBean, SolrMetricProducer

public class SyntheticSolrCore
extends SolrCore

A synthetic core that is created only in memory and not registered against Zookeeper.

This is only used in Coordinator node to support a subset of SolrCore functionalities required by Coordinator operations such as aggregating and writing out response and providing configset info.

There should only be one instance of SyntheticSolrCore per configset

bufferUpdatesIfConstructing

protected void bufferUpdatesIfConstructing(CoreDescriptor coreDescriptor)

Description copied from class: SolrCore

Set UpdateLog to buffer updates if the slice is in construction.

Overrides:

bufferUpdatesIfConstructing in class SolrCore

initRestManager

protected RestManager initRestManager()
                               throws org.apache.solr.common.SolrException

Description copied from class: SolrCore

Throws:

org.apache.solr.common.SolrException

cloneForReloadCore

protected SyntheticSolrCore cloneForReloadCore(CoreDescriptor newCoreDescriptor,
                                               ConfigSet newCoreConfig,
                                               boolean cloneCurrentState)

Description copied from class: SolrCore

Clones the current core for core reload, with the provided CoreDescriptor and ConfigSet.

Overrides:

cloneForReloadCore in class SolrCore

Returns:

the cloned core to be used for SolrCore.reload(org.apache.solr.core.ConfigSet)
