[jira] [Created] (SOLR-9184) Add convenience method to ModifiableSolrParams

Jörg Rathlev created SOLR-9184:
----------------------------------

             Summary: Add convenience method to ModifiableSolrParams
                 Key: SOLR-9184
                 URL: https://issues.apache.org/jira/browse/SOLR-9184
             Project: Solr
          Issue Type: Improvement
          Components: SolrJ
            Reporter: Jörg Rathlev
            Priority: Minor


Add a static convenience method {{ModifiableSolrParams#of(SolrParams)}} which returns the same instance if it already is modifiable, otherwise creates a new {{ModifiableSolrParams}} instance.

Rationale: when writing custom SearchComponents, we find that we often need to ensure that the SolrParams are modifiable. The copy constructor of ModifiableSolrParams always creates a copy, even if the SolrParms already are modifiable.

Alternatives: The method could also be added as a convenience method in SolrParams itself, which already has static helper methods for wrapDefaults and wrapAppended.
