Class ImmutableLongMap<A>

java.lang.Object

akka.remote.artery.ImmutableLongMap<A>

public class ImmutableLongMap<A>
extends java.lang.Object

INTERNAL API Specialized Map for primitive Long keys to avoid allocations (boxing). Keys and values are backed by arrays and lookup is performed with binary search. It's intended for rather small (<1000) maps.

Method Summary

Modifier and Type	Method and Description
boolean	contains(long key) Worst case O(log n), allocation free.
static <A> ImmutableLongMap<A>	empty(scala.reflect.ClassTag<A> t)
boolean	equals(java.lang.Object obj)
OptionVal<A>	get(long key) Worst case O(log n), allocation free.
int	hashCode()
scala.collection.Iterator<java.lang.Object>	keysIterator() All keys
ImmutableLongMap<A>	remove(long key)
int	size()
java.lang.String	toString()
ImmutableLongMap<A>	updated(long key, A value) Worst case O(log n), creates new ImmutableLongMap with copies of the internal arrays for the keys and values.
