[jira] [Created] (LUCENE-10426) Should we create a static factory method for loading VectorValues?

------------------------------------

             Summary: Should we create a static factory method for loading VectorValues?
                 Key: LUCENE-10426
                 URL: https://issues.apache.org/jira/browse/LUCENE-10426
             Project: Lucene - Core
          Issue Type: Wish
          Components: core/index
            Reporter: Greg Miller


Similar to the recent work in LUCENE-10398, it might be useful to add a static factory method for loading {{VectorValues}} that returns an "empty" {{VectorValues}} instance if the field doesn't exist in a segment (and also throws if the field is not configured as a vector field). This follows the same pattern of the static factory methods found in {{{}DocValues{}}}. 

I'm less convinced this is useful to add right now since I don't really see any existing usages of {{{}LeafReader#getVectorValues{}}}, so maybe the value isn't there right now?
