SolrParams (Solr 8.7.0 API)

java.lang.Object
- org.apache.solr.common.params.SolrParams

All Implemented Interfaces:

Serializable, Iterable<Map.Entry<String,String[]>>, MapSerializable, MapWriter, NavigableObject

Direct Known Subclasses:

DefaultSolrParams, MapSolrParams, ModifiableSolrParams, MultiMapSolrParams, RequiredSolrParams
```
public abstract class SolrParams
extends Object
implements Serializable, MapWriter, Iterable<Map.Entry<String,String[]>>
```
SolrParams is designed to hold parameters to Solr, often from the request coming into Solr. It's basically a MultiMap of String keys to one or more String values. Neither keys nor values may be null. Unlike a general Map/MultiMap, the size is unknown without iterating over each parameter name.

public abstract String get(String param)
