Method Detail

addNode

public void addNode(long entityId,
                    String key,
                    Object value)
             throws org.neo4j.kernel.api.exceptions.explicitindex.ExplicitIndexNotFoundKernelException

See Index.add(PropertyContainer, String, Object) for more generic documentation. Adds key/value to the entity in this index. Added values are searchable within the transaction, but composite AND queries aren't guaranteed to return added values correctly within that transaction. When the transaction has been committed all such queries are guaranteed to return correct results.

Specified by:

addNode in interface org.neo4j.kernel.api.ExplicitIndex

Parameters:

key - the key in the key/value pair to associate with the entity.

value - the value in the key/value pair to associate with the entity.

Throws:

org.neo4j.kernel.api.exceptions.explicitindex.ExplicitIndexNotFoundKernelException

remove

public void remove(long entityId,
                   String key,
                   Object value)

See Index.remove(PropertyContainer, String, Object) for more generic documentation. Removes key/value to the entity in this index. Removed values are excluded within the transaction, but composite AND queries aren't guaranteed to exclude removed values correctly within that transaction. When the transaction has been committed all such queries are guaranteed to return correct results.

Specified by:

remove in interface org.neo4j.kernel.api.ExplicitIndex

Parameters:

entityId - the entity (i.e Node or Relationship) to dissociate the key/value pair from.

key - the key in the key/value pair to dissociate from the entity.

value - the value in the key/value pair to dissociate from the entity.

remove

public void remove(long entityId,
                   String key)

Specified by:

remove in interface org.neo4j.kernel.api.ExplicitIndex

remove

public void remove(long entityId)

Specified by:

remove in interface org.neo4j.kernel.api.ExplicitIndex

drop

public void drop()

Specified by:

drop in interface org.neo4j.kernel.api.ExplicitIndex

get

public org.neo4j.kernel.api.ExplicitIndexHits get(String key,
                                                  Object value)
                                           throws org.neo4j.kernel.api.exceptions.explicitindex.ExplicitIndexNotFoundKernelException

Specified by:

get in interface org.neo4j.kernel.api.ExplicitIndex

Throws:

org.neo4j.kernel.api.exceptions.explicitindex.ExplicitIndexNotFoundKernelException

query

public org.neo4j.kernel.api.ExplicitIndexHits query(String key,
                                                    Object queryOrQueryObject)
                                             throws org.neo4j.kernel.api.exceptions.explicitindex.ExplicitIndexNotFoundKernelException

queryOrQueryObject can be a String containing the query in Lucene syntax format, http://lucene.apache.org/java/3_0_2/queryparsersyntax.html. Or it can be a Query object. If can even be a QueryContext object which can contain a query (String or Query) and additional parameters, such as Sort. Because of performance issues, including uncommitted transaction modifications in the result is disabled by default, but can be enabled using QueryContext.tradeCorrectnessForSpeed().

Specified by:

query in interface org.neo4j.kernel.api.ExplicitIndex

Throws:

org.neo4j.kernel.api.exceptions.explicitindex.ExplicitIndexNotFoundKernelException

query

public org.neo4j.kernel.api.ExplicitIndexHits query(Object queryOrQueryObject)
                                             throws org.neo4j.kernel.api.exceptions.explicitindex.ExplicitIndexNotFoundKernelException

Specified by:

Throws:
