Class SecureHashMap<K,V>

java.lang.Object

java.util.AbstractMap<K,V>

io.undertow.util.SecureHashMap<K,V>

Type Parameters:

K - the key type

V - the value type

All Implemented Interfaces:

ConcurrentMap<K,V>, Map<K,V>

public final class SecureHashMap<K,V>
extends AbstractMap<K,V>
implements ConcurrentMap<K,V>

Lock-free secure concurrent hash map. Attempts to store keys which cause excessive collisions will result in a security exception.
