HashFieldMap

java.lang.Object
- io.protostuff.runtime.HashFieldMap<T>

All Implemented Interfaces:

FieldMap<T>
```
final class HashFieldMap<T>
extends java.lang.Object
implements FieldMap<T>
```
Field mapping implemented on top of hash for field lookup by number. This is the less efficient than ArrayFieldMap for almost all cases. But in case when field numbers are sparse and especially when max field number is big - this mapping should be used.
