Class LookupMap<String,V>

java.lang.Object

com.joyent.manta.util.LookupMap<String,V>

Type Parameters:

String - key as string because we provide case-insensitive operations

V - value to be looking up

All Implemented Interfaces:

Map<String,V>

Direct Known Subclasses:

SupportedCiphersLookupMap, SupportedHmacsLookupMap

public class LookupMap<String,V>
extends Object
implements Map<String,V>

Custom built Map implementation that supports case-sensitive and case-insensitive operations.

Since:

3.0.0
