indexName - the name of the indexoraclePropertyGraph - an OraclePropertyGraphBase object.indexParameters - a collection of parameters for the underlying index implementation.erase - a boolean specifying if the index should be cleared at the beginning.public CloseableIterable<Vertex> get(String key, Object value, Class dtClass, boolean acceptWildcard)
get in interface OracleIndex<Vertex>get in class LuceneIndex<Vertex>key - the key of the indexed vertexs.value - the value of the indexed vertexs.acceptWildcard - specifies if wild cards can be used in the value object.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.public String getDocIdentifier()

CloseableIterable objects that hold all the vertexs with an attribute matching the given K/V pair. Each vertex in the CloseableIterable array uses a separate connection provided to fetch a subset of the results from a corresponding Lucene sub-directory. Note that we assign an integer ID (in the range of [0, N - 1]) to all the sub-directories in a Lucene index with N shards. The subset of shards (subdirectories) queried will consist of those shards with ID value in the range of [startShardId, startShardId - 1 + size of connections array].getPartitioned in interface OracleIndex<Vertex>getPartitioned in class LuceneIndex<Vertex>connections - an array of connections to the Lucene index. Each vertex of this array should be of type SearcherManager. See LuceneIndex.getOracleSearcherManager(int).key - the key of a propertyvalue - the value object of the property.acceptWildcard - specifies if wild cards can be used in the value object.startShardId - the ID of the starting shard.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 dtValue is Float.Class, then this value will be treated as a 3.01f.CloseableIterable object.Copyright © 2015 Oracle and/or its afflilates. All Rights Reserved.
