Method Detail

getIndexConfigClass

public Class<IndexConfig> getIndexConfigClass()

Specified by:

getIndexConfigClass in interface IndexType<IndexConfig,InvertedIndexReader,DictionaryBasedInvertedIndexCreator>

fromIndexLoadingConfig

public Map<String,IndexConfig> fromIndexLoadingConfig(IndexLoadingConfig indexLoadingConfig)

Description copied from interface: ConfigurableFromIndexLoadingConfig

Returns a map that can be used to get the index config. This map is used with higher priority whenever the index configuration needs to be read from an IndexLoadingConfig. Sometimes IndexLoadingConfig is not completely configured and IndexLoadingConfig.getAllKnownColumns() does not return all columns in the table. Therefore the returned map may not have an entry for each column in the actual schema.

Specified by:

fromIndexLoadingConfig in interface ConfigurableFromIndexLoadingConfig<IndexConfig>

Returns:

a map whose keys are the column names and the values are the index configuration for that column.
