[jira] [Updated] (LUCENE-7577) PrefixCodedTerms should cache its hash code

     [ https://issues.apache.org/jira/browse/LUCENE-7577?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adrien Grand updated LUCENE-7577:
---------------------------------
    Attachment: LUCENE-7577.patch

Here is a patch. The hash code is computed lazily in order not to incur a hit on consumers of this class that would not need the hash code.

> We have several queries that cache the hashcode of a PrefixCodedTerms instance on top of it, so we could simplify by moving the caching to PrefixCodedTerms directly.
