public class LinkedCaseInsensitiveMap<V>
extends java.lang.Object
implements java.util.Map<java.lang.String,V>, java.io.Serializable, java.lang.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.
Constructor and Description |
---|
LinkedCaseInsensitiveMap()
Create a new LinkedCaseInsensitiveMap that stores case-insensitive keys
according to the default Locale (by default in lower case).
|
LinkedCaseInsensitiveMap(int initialCapacity)
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(int initialCapacity,
java.util.Locale locale)
Create a new LinkedCaseInsensitiveMap that wraps a
LinkedHashMap
with the given initial capacity and stores case-insensitive keys
according to the given Locale (by default in lower case). |
LinkedCaseInsensitiveMap(java.util.Locale locale)
Create a new LinkedCaseInsensitiveMap that stores case-insensitive keys
according to the given Locale (by default in lower case).
