Class CaseInsensitiveMap

java.lang.Object
  java.util.AbstractMap<K,V>
      java.util.HashMap<String,Object>
          org.apache.camel.util.CaseInsensitiveMap

All Implemented Interfaces:

Serializable, Cloneable, Map<String,Object>

public class CaseInsensitiveMap
extends HashMap<String,Object>

A map that uses case insensitive keys, but preserves the original keys in the keySet.

This map allows you to do lookup using case insensitive keys so you can retrieve the value without worrying about whether some transport protocol affects the keys such as Http and Mail protocols can do.

When copying from this map to a regular Map such as HashMap then the original keys are copied over and you get the old behavior back using a regular Map with case sensitive keys.

This map is not designed to be thread safe as concurrent access to it is not supposed to be performed by the Camel routing engine.
