Class DatasetGraphDiff

java.lang.Object
org.apache.jena.sparql.core.DatasetGraphBase
org.aksw.jenax.arq.dataset.diff.DatasetGraphDiff
All Implemented Interfaces:
org.apache.jena.atlas.lib.Closeable, org.apache.jena.sparql.core.DatasetGraph, org.apache.jena.sparql.core.Transactional
public class DatasetGraphDiff extends org.apache.jena.sparql.core.DatasetGraphBase
A DatasetGraph that tracks insertions / deletions to a base graph in separate DatasetGraphs. Similar to Delta which however is for Graphs. Supports transactions on a best-effort basis: Invoking a transaction operation (begin, commit, rollback, end) on this class also invokes that operation on each involved component.
