Example 1 with NodeTableNative

use of org.apache.jena.tdb.store.nodetable.NodeTableNative in project jena by apache.

the class NodeTableTrans method begin.

@Override

    passthrough = false;
    allocOffset = base.allocOffset().getId();
    // base node table empty e.g. first use.
    journalObjFileStartOffset = journalObjFile.length();
    // always empty at the start of a transaction.
    if (journalObjFileStartOffset != 0)
        warn(log, "%s journalStartOffset not zero: %d/0x%02X", txn.getLabel(), journalObjFileStartOffset, journalObjFileStartOffset);
    allocOffset += journalObjFileStartOffset;
    this.nodeTableJournal = new NodeTableNative(nodeIndex, journalObjFile);
    this.nodeTableJournal = NodeTableCache.create(nodeTableJournal, CacheSize, CacheSize, 100);
    // This class knows about non-mappable inline values.   mapToJournal(NodeId)/mapFromJournal. 
    this.nodeTableJournal = NodeTableInline.create(nodeTableJournal);
