示例1: TestExpirationTimeDeletionPolicy
public virtual void TestExpirationTimeDeletionPolicy()
{
double SECONDS = 2.0;
bool autoCommit = false;
bool useCompoundFile = true;
Directory dir = new RAMDirectory();
ExpirationTimeDeletionPolicy policy = new ExpirationTimeDeletionPolicy(this, dir, SECONDS);
IndexWriter writer = new IndexWriter(dir, autoCommit, new WhitespaceAnalyzer(), true, policy);
writer.SetUseCompoundFile(useCompoundFile);
writer.Close();
long lastDeleteTime = 0;
for (int i = 0; i < 7; i++)
{
// Record last time when writer performed deletes of
// past commits

writer.SetUseCompoundFile(useCompoundFile);
for (int j = 0; j < 17; j++)

AddDoc(writer);
}
writer.Close();
// Make sure to sleep long enough so that some commit
// points will be deleted:
System.Threading.Thread.Sleep(new System.TimeSpan((System.Int64) 10000 * (int) (1000.0 * (SECONDS / 5.0))));
}
// First, make sure the policy in fact deleted something:
Assert.IsTrue(policy.numDelete > 0, "no commits were deleted");
// Then simplistic check: just verify that the
// segments_N's that still exist are in fact within SECONDS
// seconds of the last one's mod time, and, that I can
// open a reader on each:
long gen = SegmentInfos.GetCurrentSegmentGeneration(dir);
