Constructor Detail

RDBMSSolrVertexAutoIndex

public RDBMSSolrVertexAutoIndex(String indexName,
                        OraclePropertyGraph oraclePropertyGraph,
                        Parameter<String,Object>[] indexParameters,
                        boolean erase)

Constructs a new RDBMSSolrVertexAutoIndex object.

Parameters:

indexName - the name of the index

oraclePropertyGraph - an OraclePropertyGraph object.

indexParameters - a collection of parameters for the underlying index implementation.

erase - a boolean specifying if the index should be cleared at the beginning.

Method Detail

closeConnectionsArray

public void closeConnectionsArray()

Closes the connection array.

Specified by:

closeConnectionsArray in interface OracleAutoIndex<Vertex>

Specified by:

closeConnectionsArray in class SolrAutoIndex<Vertex>

getConnectionsArray

public Object[] getConnectionsArray()
                             throws SQLException

Gets the connection array.

Specified by:

getConnectionsArray in interface OracleAutoIndex<Vertex>

Specified by:

getConnectionsArray in class SolrAutoIndex<Vertex>

Returns:

an array of Connection objects

Throws:

SQLException

getElementsFromPG

public Iterable<Vertex>[] getElementsFromPG(String[] keys,
                                   Object[] connArray,
                                   int partitionId)

Gets an Iterable of vertices from the associated property graph, matching the specified keys.

Parameters:

keys - a list of the keys to be queried over the property graph.

connArray - a Connection array used for concurrent querying inside the Oracle property graph.

partitionId - the starting partition used for querying.

Returns:

an Iterable object.

getPartitionsNumber

public int getPartitionsNumber()

Gets the number of HASH partitions of the vertices table for the associated property graph.

Returns:

the number of HASH partitions of the element's table.

refreshIndex

public void refreshIndex(long lStartSCN,
                long lEndSCN)

Auto-refresh an index based on all insert/deletes between the specified start and end SCN.

Specified by:

refreshIndex in interface OracleIndex<Vertex>

Specified by:

refreshIndex in class SolrIndex<Vertex>

Parameters:

lStartSCN - start SCN value. A NULL value will be treated as MINVALUE to the underlying Oracle Database.

lEndSCN - end SCN value. A NULL value will be treated as MAXVALUE to the underlying Oracle Database.

reindexElementsPartitioned

public void reindexElementsPartitioned(String[] keys)

Re-index all elements over a non-partitioned graph.

Specified by:

reindexElementsPartitioned in interface OracleAutoIndex<Vertex>

Overrides:

reindexElementsPartitioned in class SolrAutoIndex<Vertex>

Parameters:

keys - an array of indexed keys
