Method Detail

get

public com.tinkerpop.blueprints.CloseableIterable<com.tinkerpop.blueprints.Vertex> get(java.lang.Object solrQuery)

Gets an Iterable object with all the matching elements that match the given query object. This object can be either a String text search query, a SolrQuery object or a QueryResponse from SolrCloud.

Specified by:

get in interface OracleIndex<com.tinkerpop.blueprints.Vertex>

Specified by:

get in class SolrIndex<com.tinkerpop.blueprints.Vertex>

Parameters:

solrQuery - a object representing the text query to execute.

Returns:

a CloseableIterable object.

get

public com.tinkerpop.blueprints.CloseableIterable<com.tinkerpop.blueprints.Vertex> get(java.lang.String key,
                                                                                       java.lang.Object value,
                                                                                       java.lang.Class dtClass,
                                                                                       boolean acceptWildcard)

Gets all vertices indexed by the provided key/value.

Specified by:

get in interface OracleIndex<com.tinkerpop.blueprints.Vertex>

Specified by:

get in class SolrIndex<com.tinkerpop.blueprints.Vertex>

Parameters:

key - the key of the indexed vertices.

value - the value of the indexed vertices.

dtClass - the class representing the datatype of the property value. This can be used to cast the property value to a different datatype. For example, if the value is "3.01" and dtClass is Float.Class, then this value will be treated as a 3.01f.

acceptWildcard - specifies if wild cards can be used in the value object.

Returns:

an iterable of vertices that have a particular key/value in the index.

getDocIdentifier

public java.lang.String getDocIdentifier()

Gets the document's identifier associated to this index.

Specified by:

getDocIdentifier in interface OracleIndex<com.tinkerpop.blueprints.Vertex>

Overrides:

getDocIdentifier in class SolrIndex<com.tinkerpop.blueprints.Vertex>

Returns:

the document's identifier associated to this index.

getPartitioned

public com.tinkerpop.blueprints.CloseableIterable<com.tinkerpop.blueprints.Vertex>[] getPartitioned(java.lang.Object[] connections,
                                                                                                    java.lang.Object solrQuery,
                                                                                                    int startShardId)

Gets an array of CloseableIterable objects that hold all the elements with an attribute matching the given K/V pair. Each element in the CloseableIterable array uses a separate connection provided to fetch a subset of the results from a corresponding SolrCloud shard. Note that we assign an integer ID (in the range of [0, N - 1]) to all the shards in a SolrCloud cluster with N shards. The subset of shards queried will consist of those shards with ID value in the range of [startShardId, startShardId - 1 + size of connections array].

Specified by:

getPartitioned in interface OracleIndex<com.tinkerpop.blueprints.Vertex>

Specified by:

getPartitioned in class SolrIndex<com.tinkerpop.blueprints.Vertex>

Parameters:

connections - an array of connections to the SolrCloud. Each element of this array should be of type CloudSolrClient. See SolrIndex.getCloudSolrClient(long).

solrQuery - a SolrQuery object.

startShardId - the ID of the starting shard.

Returns:

a CloseableIterable object.
