LuceneIndexImplementation

public LuceneIndexImplementation(GraphDatabaseService db,
                                 Config config)

Method Detail

nodeIndex

public Index<Node> nodeIndex(String indexName,
                             Map<String,String> config)

Description copied from class: IndexImplementation

Returns an Index for Nodes for the name indexName with the given config. The config Map can contain any provider-implementation-specific data that can control how an index behaves.

Specified by:

nodeIndex in class IndexImplementation

Parameters:

indexName - the name of the index.

config - a Map of configuration parameters to use with the index. Parameters can be anything and are implementation-specific. This map represents how the configuration looks right now, they might be modified later using IndexManager.setConfiguration(Index, String, String) or IndexManager.removeConfiguration(Index, String).

Returns:

the Index corresponding to the indexName and config.

relationshipIndex

public RelationshipIndex relationshipIndex(String indexName,
                                           Map<String,String> config)

Description copied from class: IndexImplementation

Returns an Index for Relationships for the name indexName with the given config. The config Map can contain any provider-implementation-specific data that can control how an index behaves.

Specified by:

relationshipIndex in class IndexImplementation

Parameters:

indexName - the name of the index.

config - a Map of configuration parameters to use with the index. Parameters can be anything and are implementation-specific. This map represents how the configuration looks right now, they might be modified later using IndexManager.setConfiguration(Index, String, String) or IndexManager.removeConfiguration(Index, String).

Returns:

the Index corresponding to the indexName and config. The return index is a RelationshipIndex with additional query methods for efficiently filtering hits with respect to start/end node of the relationships.

fillInDefaults

public Map<String,String> fillInDefaults(Map<String,String> source)

Description copied from class: IndexImplementation

Fills in default configuration parameters for indexes provided from this index provider.

Specified by:

fillInDefaults in class IndexImplementation

Parameters:

source - the configuration map to complete with defaults.

Returns:

a Map filled with decent defaults for an index from this index provider.

configMatches

public boolean configMatches(Map<String,String> storedConfig,
                             Map<String,String> config)

Specified by:

configMatches in class IndexImplementation

getDataSourceName

public String getDataSourceName()

Description copied from class: IndexImplementation

Returns the name of the XA data source coupled with this index provider.

Specified by:

getDataSourceName in class IndexImplementation

Returns:

the name of the XA data source coupled with this index provider.
