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.

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	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.
