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

Description

Interface Summary

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

Class Summary

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.
DefaultGraphSolutionExpander	Solution expander provides an efficient merged access path for the graphs in the SPARQL default graph.
DistinctSPOIterator	Iterator using a BTree filter out duplicate (s,p,o) tuples.
DistinctTermAdvancer	Advances the source ITupleCursor through the distinct term identifiers for some SPOAccessPath.
ExplicitSPOFilter	Filter matches only StatementEnum.Explicit ISPOs.
FastRDFValueCoder	Deprecated. by FastRDFValueCoder2
FastRDFValueCoder2	Coder for statement index with inference enabled but without SIDS.
InferredSPOFilter	Filter matches only StatementEnum.Inferred statements.
InGraphBinarySearchFilter	"IN" filter for the context position based on a sorted long[] of the acceptable graph identifiers.
InGraphHashSetFilter	"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
NamedGraphSolutionExpander	Solution expander provides an efficient merged access path for SPARQL named graphs.
NoAxiomFilter	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.
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
SPOIndexRemover	Class writes on a statement index, removing the specified statements (batch API, no truth maintenance).
SPOIndexWriteProc	Procedure for batch index 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.
SPOTupleSerializer	(De-)serializes SPOs for statement indices.
StatementWriter	Deprecated. by SPORelation.insert(IChunkedOrderedIterator)? (Still used by copyStatements)

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.
