示例1: WriteFieldUpdates
//.........这里部分代码省略.........
{
fieldsConsumer.Dispose();
}
else
{
IOUtils.CloseWhileHandlingException(fieldsConsumer);
}
}
}
finally
{
if (reader != this.Reader)
{
// System.out.println("[" + Thread.currentThread().getName() + "] RLD.writeLiveDocs: closeReader " + reader);
reader.Dispose();
}
}
success = true;
}
finally
{
if (!success)
{
// Advance only the nextWriteDocValuesGen so that a 2nd
// attempt to write will write to a new file
Info.AdvanceNextWriteFieldInfosGen();
// Delete any partially created file(s):
foreach (string fileName in trackingDir.CreatedFiles)
{
try
{
dir.DeleteFile(fileName);
}
catch (Exception)
{
// Ignore so we throw only the first exc
}
}
}
}
Info.AdvanceFieldInfosGen();
// copy all the updates to mergingUpdates, so they can later be applied to the merged segment
if (IsMerging)
{
foreach (KeyValuePair<string, NumericDocValuesFieldUpdates> e in dvUpdates.NumericDVUpdates)
{
DocValuesFieldUpdates updates;
if (!MergingDVUpdates.TryGetValue(e.Key, out updates))

}
else

updates.Merge(e.Value);
}

{
DocValuesFieldUpdates updates;
if (!MergingDVUpdates.TryGetValue(e.Key, out updates))
{

}示例2: WriteLiveDocs
// Commit live docs (writes new _X_N.del files) and field updates (writes new
// _X_N updates files) to the directory; returns true if it wrote any file
// and false if there were no new deletes or updates to write:
// TODO (DVU_RENAME) to writeDeletesAndUpdates
public virtual bool WriteLiveDocs(Directory dir)
{
lock (this)
{
//Debug.Assert(Thread.holdsLock(Writer));
//System.out.println("rld.writeLiveDocs seg=" + info + " pendingDelCount=" + pendingDeleteCount + " numericUpdates=" + numericUpdates);
if (PendingDeleteCount_Renamed == 0)
{
return false;
}
// We have new deletes
Debug.Assert(LiveDocs_Renamed.Length() == Info.Info.DocCount);
// Do this so we can delete any created files on
// exception; this saves all codecs from having to do
// it:
TrackingDirectoryWrapper trackingDir = new TrackingDirectoryWrapper(dir);
// We can write directly to the actual name (vs to a
// .tmp & renaming it) because the file is not live
// until segments file is written:
bool success = false;
try
{
Codec codec = Info.Info.Codec;
codec.LiveDocsFormat().WriteLiveDocs((MutableBits)LiveDocs_Renamed, trackingDir, Info, PendingDeleteCount_Renamed, IOContext.DEFAULT);
success = true;
}
finally
{
if (!success)
{
// Advance only the nextWriteDelGen so that a 2nd
// attempt to write will write to a new file
Info.AdvanceNextWriteDelGen();
// Delete any partially created file(s):
foreach (string fileName in trackingDir.CreatedFiles)
{
try
{
dir.DeleteFile(fileName);
}
catch (Exception)
{
// Ignore so we throw only the first exc
}
}
}
}
// If we hit an exc in the line above (eg disk full)
// then info's delGen remains pointing to the previous
// (successfully written) del docs:
Info.AdvanceDelGen();
Info.DelCount = Info.DelCount + PendingDeleteCount_Renamed;
PendingDeleteCount_Renamed = 0;
return true;
