Class DatasetGraphTextMonitor

java.lang.Object
org.apache.jena.sparql.core.DatasetGraphWrapper
org.apache.jena.query.text.changes.DatasetGraphTextMonitor
All Implemented Interfaces:
org.apache.jena.atlas.lib.Closeable, org.apache.jena.atlas.lib.Sync, org.apache.jena.sparql.core.DatasetGraph, org.apache.jena.sparql.core.Transactional
Direct Known Subclasses:
DatasetGraphText
public class DatasetGraphTextMonitor extends org.apache.jena.sparql.core.DatasetGraphWrapper
Connect a DatasetGraph to a DatasetChanges monitor. Any add or delete to the DatasetGraph is notified to the monitoring object with a TextQuadAction to indicate the change made.

  • Constructor Details

    • DatasetGraphTextMonitor

      public DatasetGraphTextMonitor(org.apache.jena.sparql.core.DatasetGraph dsg, TextDatasetChanges monitor)
      Create a DatasetGraph wrapper that monitors the dataset for changes (add or delete quads). Use this DatasetGraph for all operations in order to record changes. Note whether additions of deletions cause an actual change to the dataset or not.
      Parameters:
      dsg - The DatasetGraph to monitor
      monitor - The handler for a change

    • DatasetGraphTextMonitor

      public DatasetGraphTextMonitor(org.apache.jena.sparql.core.DatasetGraph dsg, TextDatasetChanges monitor, boolean recordOnlyIfRealChange)
      Create a DatasetGraph wrapper that monitors the dataset for changes (add or delete quads). Use this DatasetGraph for all operations in order to record changes.
      Parameters:
      dsg - The DatasetGraph to monitor
      monitor - The handler for a change
      recordOnlyIfRealChange - If true, check to see if the change would have an effect (e.g. add is a new quad). If false, log changes as ADD/DELETE regardless of whether the dataset actually changes.
