Class CaseInsensitiveMap<V>

  • Type Parameters:
    V - the type of value stored
    All Implemented Interfaces:, java.util.Map<java.lang.String,​V>

    public class CaseInsensitiveMap<V>
    extends java.util.AbstractMap<java.lang.String,​V>
    An mapped collection where the keys are always strings and access to values is case-insensitive. The case of keys in the map is maintained, but on any access to a key (directly or indirectly), all key comparisons are performed in a case-insensitive manner. The map implementation is intended to support a reasonably finite number (dozens or hundreds, not thousands or millions of key/value pairs. Unlike HashMap, it is based on a sorted list of entries rather than hash bucket. It is also geared towards a largely static map, one that is created and then used without modification.
