Package com.bigdata.rdf.store

This package provides several realizations of an RDF database using the bigdata architecture, including one suitable for temporary data, one suitable for local processing (single host), and one designed for scale-out on commodity hardware.

BD	A vocabulary for bigdata specific extensions.
BDS	A vocabulary for the bigdata full text search facility.
BigdataStatementIterator	Iterator visiting BigdataStatements.
BigdataValueIterator	Iterator visiting BigdataValues.
DataLoader.Options	Options for the DataLoader.
IRawTripleStore	Low-level API directly using long term identifiers rather than an RDF Value object model.

Class Summary

Class	Description
AbstractDistributedBigdataFederationTestCase	An abstract test harness that sets up (and tears down) the metadata and data services required for a bigdata federation using JINI to handle service discovery.
AbstractDistributedTripleStoreTestCase	Abstract test case that sets up and connects to a bigdata federation and establishes an RDF database on that federation.
AbstractEmbeddedBigdataFederationTestCase	An abstract test harness that sets up (and tears down) the metadata and data services required for a bigdata federation using in-process services rather than service discovery (which means that there is no network IO).
AbstractEmbeddedTripleStoreTestCase
AbstractLocalTripleStore	Abstract base class for both transient and persistent ITripleStore implementations using local storage.
AbstractTestCase	Abstract harness for testing under a variety of configurations.
AbstractTestCase.StatementVerifier	Helper class verifies that all statements identified by a re-parse of some RDF/XML file are present in the KB.
AbstractTripleStore	Abstract base class that implements logic for the ITripleStore interface that is invariant across the choice of the backing store.
AbstractTripleStoreTestCase	Base class for test suites for inference engine
BigdataBindingSetResolverator	Efficiently resolve term identifiers in Bigdata IBindingSets to RDF BigdataValues.
BigdataOpenRDFBindingSetsResolverator	Efficiently resolve openrdf BindingSets to bigdata IBindingSets (this is a streaming API).
BigdataSolutionResolverator	Efficiently resolve term identifiers in Bigdata ISolutions to RDF BigdataValues.
BigdataStatementIteratorImpl	Efficiently resolve term identifiers in Bigdata ISPOs to RDF BigdataValues.
BigdataTriplePattern	A simple class that represents a triple (or quad) pattern.
BigdataTriplePatternMaterializer	Efficient batched, streaming resolution of triple patterns to statements spanned by those triple patterns that are present in the data.
BigdataValueIteratorImpl	Wraps an iterator that visits term identifiers and exposes each visited term identifier as a BigdataValue (batch API).
DataLoader	A utility class to load RDF data into an AbstractTripleStore.
DumpStore	Utility class may be used to dump out a small database.
EmptyStatementIterator	Empty iterator.
LocalTripleStore	A triple store based on the bigdata architecture.
ProxyTestCase	This class provides proxy delegation logic for abstract methods declared by AbstractTestCase and is used to extend the set of tests that will be applied to all implementations of the generic object model Java API.
RebuildTextIndex	A utility class to rebuild text index in an AbstractTripleStore.
ScaleOutTripleStore	Implementation of an ITripleStore as a client of an IBigdataFederation.
StressTestCentos	This is a test class that fails on centos 64bit.
TempTripleStore	A temporary triple store based on the bigdata architecture.
TestAll	Runs tests for each ITripleStore implementation.
TestBlobsConfiguration	Test suite for configuration of the BLOBS index support.
TestBulkFilter	Test bulk filter API.
TestDataLoader	Test suite for the DataLoader.
TestInlineURIs	Integration test suite for InlineURIFactory (the inline IVs are also tested in their own package without the triple store integration).
TestInlineURIs.CustomInlineURIFactory
TestInlineURIs.CustomVocab	Note: Must be public for access patterns.
TestInlineURIs.InlineArrayFactory
TestInlineURIs.InlineArrayHandler
TestInlineURIs.MultipurposeInlineIDFactory
TestInlineURIs.MultipurposeInlineIDHandler
TestInsertRate	A test for measuring the possible insert rate for a triple store based on a journal and btree using a synthetic data generator.
TestInsertRate.XMLSchema	Defines a variety of URIs relevant to the XML Schema Datatypes specification.
TestIsModified	Test suite for ISPO.isModified().
TestLocalQuadStore	Proxy test suite for LocalTripleStore in quad-store mode.
TestLocalTripleStore	Proxy test suite for LocalTripleStore when the backing indices are BTrees.
TestLocalTripleStoreDestroy	Test suite to verify the semantics of destroying a LocalTripleStore, including verifying that the indices are deleted (gone from Name2Addr), that the locator is cleared from the DefaultResourceLocator, and that the entries from the AbstractTripleStore are removed from the global row store.
TestLocalTripleStoreTransactionSemantics	Test suite for the transaction semantics of the LocalTripleStore.
TestLocalTripleStoreWithoutInlining	Proxy test suite for LocalTripleStore when the backing indices are BTrees.
TestLocalTripleStoreWithoutStatementIdentifiers	Proxy test suite for LocalTripleStore when the backing indices are BTrees.
TestRelationLocator	Test suite for locating an AbstractTripleStore, locating the LexiconRelation and SPORelation from the AbstractTripleStore, and locating the AbstractTripleStore from its contained relations.
TestRestartSafe	Test restart safety for the various indices.
TestScaleOutTripleStoreWithEmbeddedFederation	Proxy test suite for ScaleOutTripleStore running against an EmbeddedFederation.
TestSharedLexiconTempStore	Test suite for TempTripleStores sharing the same LexiconRelation as the primary AbstractTripleStore.
TestStatementIdentifiers	Test of the statement identifier semantics.
TestTempTripleStore	Proxy test suite for TempTripleStore.
TestTripleStore	Test basic features of the ITripleStore API.
TestTripleStoreBasics	Aggregates test that are run for each ITripleStore implementation.
TripleStoreSchema	Extensions for additional state maintained by the AbstractTripleStore in the global row store.
TripleStoreUtility	Utility class for comparing graphs for equality, bulk export, etc.

Enum Summary

Enum	Description
DatabaseMode
DataLoader.ClosureEnum	A type-safe enumeration of options effecting whether and when entailments are computed as documents are loaded into the database using the DataLoader.
DataLoader.CommitEnum	A type-safe enumeration of options effecting whether and when the database will be committed.
