Class CaseInsensitiveStringMap

Object
org.apache.spark.sql.util.CaseInsensitiveStringMap
All Implemented Interfaces:
Map<String,String>

@Experimental public class CaseInsensitiveStringMap extends Object implements Map<String,String>
Case-insensitive map of string keys to string values.

This is used to pass options to v2 implementations to ensure consistent case insensitivity.

Methods that return keys in this map, like entrySet() and keySet(), return keys converted to lower case. This map doesn't allow null key.
