Package com.bigdata.rdf.spo

This package defines a statement model using long term identifiers rather than RDF Value objects.

See: Description

Interface Summary

Interface	Description
IBinding	Interface for a binding.
ISPO	A interface representing an RDF triple, an RDF triple with a statement identifier, or an RDF quad.
ISPOAssertionBuffer	A buffer that is written on by Rules.
ISPOBuffer	Deprecated by IBuffer
SPOPredicate.Annotations
SPOStarJoin.Annotations

Class Summary

Class	Description
Binding	Implementation of a binding.
BulkCompleteConverter	Bulk completes the StatementEnum and/or statement identifier (SID) for ISPOs using the given statement IIndex.
BulkFilterConverter	Bulk filters for ISPOs either present or NOT present in the target statement IIndex.
ContextAdvancer	Advancer for a quads index whose last key component is the "context position (such as SPOC or SOPC).
DistinctMultiTermAdvancer	This was cloned from the DistinctTermAdvancer.
DistinctSPOIterator	Deprecated By a simple distinct filter and a filter which strips off the context position from an SPOC.
DistinctTermAdvancer	Advances the source ITupleCursor through the distinct term identifiers for some AccessPath.
ExplicitSPOFilter<E extends ISPO>	Filter matches only StatementEnum.Explicit ISPOs.
FastRDFValueCoder2	Coder for values in statement index with inference enabled but without SIDS.
HistorySPOFilter<E extends ISPO>	Filters out StatementEnum.History ISPOs.
InferredSPOFilter<E extends ISPO>	Filter matches only StatementEnum.Inferred statements.
InGraphBinarySearchFilter<E extends ISPO>	"IN" filter for the context position based on a sorted long[] of the acceptable graph identifiers.
InGraphHashSetFilter<E extends ISPO>	"IN" filter for the context position based on a native long hash set containing the acceptable graph identifiers.
JustificationRemover	Class writes on the justification index, removing all Justifications for each statement specified by the caller.
JustificationTupleSerializer	(De-)serializes Justifications.
JustificationWriter	Writes Justifications on the justification index.
JustIndexWriteProc	Procedure for writing Justifications on an index or index partition.
JustIndexWriteProc.WriteJustificationsProcConstructor
NoAxiomFilter<E extends ISPO>	A filter that matches explicit or inferred statements but not those whose StatementEnum is StatementEnum.Axiom.
OSPComparator	Imposes o:s:p ordering based on termIds only.
POSComparator	Imposes p:o:s ordering based on termIds only.
RDFValueFactory	Factory for the single element byte[] used for the value of an RDF Statement in one of the statement indices.
SPO	Represents a triple, triple+SID, or quad.
SPOAccessPath	IAccessPath implementation for an SPORelation.
SPOArrayIterator	Deprecated by ChunkedArrayIterator but this still has some very purpose specific uses mainly dealing with TruthMaintenance and with fully buffering precisely because the DB impl is not using concurrency controls.
SPOComparator<T extends ISPO>	Imposes s:p:o ordering based on termIds only (ignores StatementEnum).
SPOFilter<E extends ISPO>
SPOIndexRemover	Class writes on a statement index, removing the specified statements (batch API, no truth maintenance).
SPOIndexWriteProc	Procedure for batch insert on a single statement index (or index partition).
SPOIndexWriteProc.IndexWriteProcConstructor
SPOIndexWriter	Helper class writes an ISPO[] on one of the statement indices.
SPOKeyOrder	Represents the key order used by an index for a triple relation.
SPOPredicate	A predicate that is a triple with one or more variables.
SPORelation	The SPORelation handles all things related to the indices representing the triples stored in the database.
SPOSortKeyBuilder	Class produces unsigned byte[] sort keys for ISPOs.
SPOStarJoin	Implementation of a star join for SPOs.
SPOStarJoin.SPOStarConstraint	Implementation of a star constraint for SPOs.
SPOTupleSerializer	(De-)serializes SPOs for statement indices.
StatementWriter	Deprecated by SPORelation.insert(IChunkedOrderedIterator)? (Still used by copyStatements)
TestAll	Aggregates test suites into increasing dependency order.
TestSPO	Test suite for the SPO class.
TestSPOAccessPath	Test suite for SPOAccessPath.
TestSPOKeyCoders	Test suite for approaches to key compression for statement indices (keys are permutations on SPOC, logically comprised of long[4] and encoded as byte[]), the terms index (key is byte[] encoding the URI, literal, or bnode ID), or the ids index (key is byte[] encoding a long term identifier).
TestSPOKeyOrder	Test suite for SPOKeyOrder.
TestSPOPredicate	Test suite for SPOPredicate.
TestSPORelation	Test ability to insert, update, or remove elements from a relation and the ability to select the right access path given a predicate for that relation and query for those elements (we have to test all this stuff together since testing query requires us to have some data in the relation).
TestSPORelation.P
TestSPOStarJoin
TestSPOTupleSerializer	Test suite for SPOTupleSerializer.
TestSPOValueCoders	Test suite for approaches to value compression for statement indices.
TestStatementEnum	Test suite for StatementEnum.
TestXXXCShardSplitHandler	Test suite for the XXXCShardSplitHandler.
XXXCShardSplitHandler	A split handler for the xxxC quads indices which ensures that all quads for the same "triple" are in the same shard.

Package com.bigdata.rdf.spo Description

This package defines a statement model using long term identifiers rather than RDF Value objects. This model is used when writing queries or rules that run directly against an RDF database.
