Method Detail

createConfigSetService

public static ConfigSetService createConfigSetService(NodeConfig nodeConfig,
                                                      SolrResourceLoader loader,
                                                      ZkController zkController)

loadConfigSet

public final ConfigSet loadConfigSet(CoreDescriptor dcore)

Load the ConfigSet for a core

Parameters:

dcore - the core's CoreDescriptor

Returns:

a ConfigSet

createSolrConfig

protected SolrConfig createSolrConfig(CoreDescriptor cd,
                                      SolrResourceLoader loader,
                                      boolean isTrusted)

Create a SolrConfig object for a core

Parameters:

cd - the core's CoreDescriptor

loader - the core's resource loader

isTrusted - is the configset trusted?

Returns:

a SolrConfig object

createIndexSchema

protected IndexSchema createIndexSchema(CoreDescriptor cd,
                                        SolrConfig solrConfig)

Create an IndexSchema object for a core. It might be a cached lookup.

Parameters:

cd - the core's CoreDescriptor

solrConfig - the core's SolrConfig

Returns:

an IndexSchema

getCurrentSchemaModificationVersion

protected abstract Long getCurrentSchemaModificationVersion(String configSet,
                                                            SolrConfig solrConfig,
