Interface Summary

Interface	Description
ISubjectCentricTextIndexer<A extends IHit>	Abstraction for the text indexer for RDF Values allowing either the built-in bigdata FullTextIndex or support for Lucene, etc.
ITermCache<K extends IV<?,?>,V extends BigdataValue>	Reduced interface for the LexiconRelation's term cache.
ITermIndexCodes	This interface defines the signed byte values indicating the type of a term in the term index.
ITermIVFilter	Interface for filtering internal values.
ITextIndexer<A extends IHit>	Abstraction for the text indexer for RDF Values allowing either the built-in bigdata FullTextIndex or support for Lucene, etc.
IValueCentricTextIndexer<A extends IHit>	Abstraction for the text indexer for RDF Values allowing either the built-in bigdata FullTextIndex or support for Lucene, etc.

Class Summary

Class	Description
AssignTermId	Assigns the term identifier to duplicate BigdataValue for a single write operation when an IDuplicateRemover was applied.
BigdataSubjectCentricFullTextIndex	Implementation based on the built-in keyword search capabilities for bigdata.
BigdataValueCentricFullTextIndex	Implementation based on the built-in keyword search capabilities for bigdata.
BlobsIndexHelper	Helper class for operations on the BLOBS index.
BlobsIndexSplitHandler	Split handler enforces the constraint that a collision bucket is never split across a shard boundary.
BlobsTupleSerializer	Encapsulates key and value formation for the TERMS index.
BlobsWriteProc	This unisolated operation inserts Values into the {termCode,hash(Value),counter}:Value index, assigning IVs to Values as a side-effect.
BlobsWriteProc.BlobsWriteProcConstructor
BlobsWriteProc.Result	Object encapsulates the discovered / assigned IVs and provides efficient serialization for communication of those data to the client.
BlobsWriteTask	Synchronous RPC write on the TERMS index.
CacheValueFilter	Cache the BigdataValue on the IV (create a cross linkage).
Id2TermTupleSerializer	Encapsulates key and value formation for the reverse lexicon index.
Id2TermWriteProc	Unisolated write operation makes consistent assertions on the id:term index based on the data developed by the Term2IdWriteProc operation.
Id2TermWriteProc.Id2TermWriteProcConstructor
ITextIndexer.FullTextQuery
IVDocIdExtension	Implementation provides for the use of IVs in the FullTextIndex.
KVOTermIdComparator	Places KVOs containing BigdataValue references into an ordering determined by the assigned term identifiers}.
LexiconKeyBuilder	Flyweight helper class for building (and decoding to the extent possible) unsigned byte[] keys for RDF Values and term identifiers.
LexiconKeyOrder	Natural index orders for the LexiconRelation.
LexiconRelation	The LexiconRelation handles all things related to the indices mapping external RDF Values onto IVs (internal values)s and provides methods for efficient materialization of external RDF Values from IVs.
LexPredicate	A lex(BigdataValue,IV) predicate used for querying the LexiconRelation's TERMS index.
RDFFullTextIndexTupleSerializer	Replaces the FullTextIndexTupleSerializer to support IVs as document identifiers.
ReverseIndexWriterTask	Add terms to the reverse index, which is the index that we use to lookup the RDF value by its term identifier so that we can externalize ISPOs as RDF/XML or the like.
Term2IdTupleSerializer	Handles the term:id index (forward mapping for the lexicon).
Term2IdWriteProc	This unisolated operation inserts terms into the term:id index, assigning identifiers to terms as a side-effect.
Term2IdWriteProc.Result	Object encapsulates the discovered / assigned term identifiers and provides efficient serialization for communication of those data to the client.
Term2IdWriteProc.Term2IdWriteProcConstructor
Term2IdWriteTask	Synchronous RPC write on the TERM2ID index.
TermCache<K extends IV<?,?>,V extends BigdataValue>
TermIdEncoder	An encoder/decoder for long values formed from a partition identifier in the high word and a local counter in the low word where the low N bits of the long value are reversed and rotated into the high N bits of the long value.
TestAccessPaths	Test suite for LexiconRelation.newAccessPath(IIndexManager, IPredicate, IKeyOrder).
TestAddTerms	Test suite for adding terms to the lexicon.
TestAll	Aggregates test suites into increasing dependency order.
TestBlobsIndex	Test suite for low-level operations on the BLOBS index.
TestBlobsWriteTask	Test suite for the BlobsWriteTask.
TestCompletionScan	Unit tests for LexiconRelation.prefixScan(org.openrdf.model.Literal[]).
TestFullTextIndex	Test of adding terms with the full text index enabled and of lookup of terms by tokens which appear within those terms.
TestId2TermTupleSerializer	Test suite for Id2TermTupleSerializer.
TestInlining	Test suite for adding terms to the lexicon.
TestInlining.MyVocabulary	Declares URIs to support the IExtension examples.
TestIVCache	Test suite for IVCache.getValue(), which provides a cache on the IV for a materialized BigdataValue.
TestLexAccessPatternEnum	Test suite for LexAccessPatternEnum.
TestLexiconKeyBuilder	Test suite for LexiconKeyBuilder.
TestSubjectCentricFullTextIndex	Deprecated Feature was never completed due to scalability issues.
TestTermIdEncoder	Unit test for unified encoding / decoding for partitioned and unpartitioned long counters as assigned by the ICounter for a TERM2ID index or index partition.
TestTermIVComparator	Test suite for TermIVComparator.
TestVocabulary	Test suite for the Vocabulary implementations in the context of an AbstractTripleStore.
WriteTaskStats	Class for reporting various timings for writes on the lexicon indices.

Enum Summary

Enum	Description
LexAccessPatternEnum	Type safe enumeration of access patterns for the LexPredicate.

Exception Summary

Exception	Description
BlobsIndexHelper.CollisionBucketSizeException	Exception thrown if the maximum size of the collision bucket would be exceeded for some BigdataValue.
