Constructor Detail

RDBMSLuceneVertexIndex

public RDBMSLuceneVertexIndex(java.lang.String indexName,
                              OraclePropertyGraph oraclePropertyGraph,
                              com.tinkerpop.blueprints.Parameter<java.lang.String,java.lang.Object>[] indexParameters,
                              boolean erase)

Constructs a new RDBMSLuceneVertexIndex 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

getOracleDirectory

public OracleDirectory getOracleDirectory()

Gets the Oracle Directory storing all index data. This directory is obtained based on the configurations specified in the index parameters.

Overrides:

getOracleDirectory in class LuceneIndex<com.tinkerpop.blueprints.Vertex>

Returns:

an OracleDirectory object.

getOraclePool

public OraclePool[] getOraclePool(java.util.Map<java.lang.String,java.lang.Object> indexParams)

Get the Oracle Pool associated to the specified index parameters

Returns:

an OraclePool object.

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<com.tinkerpop.blueprints.Vertex>

Overrides:

refreshIndex in class LuceneVertexIndex

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.
