Method Detail

isExclusiveIndexUsageEnabled

public static boolean isExclusiveIndexUsageEnabled(Properties indexProps)

isExclusiveIndexUsageEnabled.

Parameters:

indexProps - a Properties object.

isIndexMetadataComplete

public static boolean isIndexMetadataComplete(Properties indexProps,
                              WorkerBuildContext context)

Returns the configured value of Environment.INDEX_METADATA_COMPLETE for this specific index. If no value is set, the default is defined by SearchConfiguration.isIndexMetadataComplete().

Parameters:

indexProps - The index configuration properties

context - The WorkerBuildContext provides a view of the default setting

Returns:

true when the index metadata is fully defined.

extractMaxQueueSize

public static int extractMaxQueueSize(String indexName,
                      Properties indexProps)

Parameters:

indexName - the index name (used for logging)

indexProps - MaskedProperties for this IndexManager

Returns:

the maximum queue length to be used on the backends of this index

getOptimizerStrategy

public static OptimizerStrategy getOptimizerStrategy(IndexManager callback,
                                     Properties indexProps)

extractIndexingPerformanceOptions

public static LuceneIndexingParameters extractIndexingPerformanceOptions(Properties properties)

Creates a new LuceneIndexingParameters instance for the specified provider. If there are no matching properties in the configuration default values will be applied.

NOTE:
If a non batch value is set in the configuration apply it also to the batch mode. This covers the case where users only specify parameters for the non batch mode. In this case the same parameters apply for batch indexing. Parameters are found "depth-first": if a batch parameter is set in a global scope it will take priority on local transaction parameters.

Parameters:

properties - The properties extracted from the configuration.

createDirectoryBasedReaderProvider

public static DirectoryBasedReaderProvider createDirectoryBasedReaderProvider(DirectoryBasedIndexManager indexManager,
                                                              Properties cfg)
