Examples of org.apache.solr.common.util.SimpleOrderedMap

org.apache.solr.common.util.SimpleOrderedMap
SimpleOrderedMap is a {@link NamedList} where access by key is moreimportant than maintaining order when it comes to representing the held data in other forms, as ResponseWriters normally do. It's normally not a good idea to repeat keys or use null keys, but this is not enforced. If key uniqueness enforcement is desired, use a regular {@link Map}.
For example, a JSON response writer may choose to write a SimpleOrderedMap as {"foo":10,"bar":20} and may choose to write a NamedList as ["foo",10,"bar",20]. An XML response writer may choose to render both the same way.

This class does not provide efficient lookup by key, it's main purpose is to hold data to be serialized. It aims to minimize overhead and to be efficient at adding new elements.
