Code_Examples
Various test cases located in bigdata/src/test, bigdata-rdf/src/test, bigdata-sail/src/test packages could be useful for you as code examples demonstrating using Blazegraph in different situations.
For example:
| Class Name | Description |
|---|---|
| SampleCode | Demonstrate how to use bigdata. You are free to use this code for whatever purpose without restriction. |
| SparqlBuilder | Demonstrate how to use bigdata. You are free to use this code for whatever purpose without restriction. |
| NSSEmbeddedExample | Class demonstrates how to start the NanoSparqlServer from within embedded code. |
| TestAccessPaths | Test suite for LexiconRelation newAccessPath(IIndexManager, IPredicate, IKeyOrder). |
| TestAddTerms | Test suite for adding terms to the lexicon. |
| TestFullTextIndex | Test of adding terms with the full text index enabled and of lookup of terms by tokens which appear within those terms. |
| TestBigdataSailWithQuads | Test suite for the BigdataSail with quads enabled. The provenance mode is disabled. Inference is disabled. This version of the test suite uses the pipeline join algorithm. |
| TestQuadsAPI | Unit tests the quads aspects of the BigdataSail implementation. |
| TestProvenanceQuery | Test suite for high-level query against a graph containing statements about statements. |
| TestSearchQuery | Test suite for high-level query against a graph containing statements about statements. |
| TestEncodeDecodeValue | Test suite for utility class to encode and decode RDF Values for interchange via the REST API. |
| TestSubqueryPatterns | Test suite for translating queries which use subquery constructions |
| TestTriplePatternBuilder | Test suite for building up triple patterns |
| TestSPO | Test suite for the SPO class. |
| TestSPOAccessPath | Test suite for SPOAccessPath. |
| 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 |
| JournalExample | This example show how to create a Journal, register a BTree and perform basic operations on the BTree. The Journal is the right choice when you want a standalone persistence store. When using the Journal in this manner, you must remember to Journal commit() your write sets. |
| JournalReadOnlyTxExample | This example illustrates how to safely interact with a zero retention configuration of the RWStore using a mixture of read-only transactions and unisolated index writes. |
| JournalTxExample | This example show how to create a Journal, register a BTree, start a transaction, obtain a B+Tree view isolated by that transaction, perform basic operations on the BTree, and commit the transaction. |
| ReadWriteIndexExample | This example shows how to wrap a B+Tree with a skin which makes it thread safe for concurrent readers and writers (the underlying B+Tree implementation is already thread-safe for concurrent readers, but is single-threaded for mutation). |
| ReadWriteIndexTxExample | This example shows how to wrap a B+Tree with a skin which makes it thread safe for concurrent readers and writers (the underlying B+Tree implementation is already thread-safe for concurrent readers, but is single-threaded for mutation). |
| TempStoreExample | Sample for for using the BTree with a TemporaryStore. |
