PackedMap (Jenkins core 2.453 API)

java.lang.Object
- java.util.AbstractMap<K,V>
- - hudson.util.PackedMap<K,V>

All Implemented Interfaces:

Map<K,V>
```
public final class PackedMap<K,V>
extends AbstractMap<K,V>
```
Read-only map implementation that uses less memory than HashMap/TreeMap.
The implementation is backed by a single exact-length array, so this implementation has the following performance characteristics.
- iteration is fast (but creates a lot of short-lived objects.)
- lookup is O(N)
- memory consumption is low
