LinkedCaseInsensitiveMap

open class LinkedCaseInsensitiveMap<V : Any> : MutableMap<String, V>, Serializable, Cloneable

LinkedHashMap variant that stores String keys in a case-insensitive manner, for example for key-based access in a results table.

Preserves the original order as well as the original casing of keys, while allowing for contains, get and remove calls with any case of key.

Does not support null keys.

LinkedCaseInsensitiveMap(initialCapacity: Int)

Create a new LinkedCaseInsensitiveMap that wraps a LinkedHashMap with the given initial capacity and stores case-insensitive keys according to the default Locale (by default in lower case).

LinkedCaseInsensitiveMap(initialCapacity: Int, locale: Locale)
