3.0.3 Migration BinaryDocValues sample usage
Hi community,
Im looking at the migration guide and in regard to getting the Values from the field cache it says:
If you had code like this before:
String[] values = FieldCache.DEFAULT.getStrings(reader, field);
...
String aValue = values[docID];
you can do this instead:
DocTerms values = FieldCache.DEFAULT.getTerms(reader, field);
...
BytesRef term = new BytesRef();
String aValue = values.getTerm(docID, term).utf8ToString();
For some reason we don't have DocTerms in Lucene.Net but we do have BinaryDocValues instead.
So I need guidance as to how to implement the Get method in the BinaryDocValues class specially because I don't know what I'm supposed to do with the docID parameter
Previously I had an array of strings and I would just pass in the docId and get the string but here how do I use the BinaryDocValue? This is how I get the BinaryDocValue
Private currentReaderValues As ReaderValues
Public Overrides Function SetNextReader(context As AtomicReaderContext) As FieldComparer
currentReaderValues = FieldCache.DEFAULT.GetTerms(context.AtomicReader, field, False)
Return Me
End Function
Public Class ReaderValues
Inherits BinaryDocValues
Public Overrides Sub [Get](docID As Integer, result As BytesRef)
'TODO How to deal with this do I just return the result.ToUtf8String()?
End Sub
End Class
