Digy commented on LUCENENET-412:
--------------------------------
One more sample
{code}
From:
class AnonymousFilterCache : FilterCache
{
class AnonymousFilteredDocIdSet : FilteredDocIdSet
{
IndexReader r;
public AnonymousFilteredDocIdSet(DocIdSet innerSet,
IndexReader r) : base(innerSet)
{
this.r = r;
}
public override bool Match(int docid)
{
return !r.IsDeleted(docid);
}
}
public AnonymousFilterCache(DeletesMode deletesMode) :
base(deletesMode)
{
}
protected override object MergeDeletes(IndexReader reader,
object docIdSet)
{
return new
AnonymousFilteredDocIdSet((DocIdSet)docIdSet, reader);
}
}
.......
cache = new AnonymousFilterCache(deletesMode);
To:
cache = new FilterCache<DocIdSet>(deletesMode,
(reader,docIdSet)=>{
return new FilteredDocIdSet((DocIdSet)docIdSet,
(docid) =>
{
return !reader.IsDeleted(docid);
});
});
{code}
