Class HashFieldMapEx<T>

java.lang.Object

io.protostuff.runtime.HashFieldMapEx<T>

All Implemented Interfaces:

FieldMapEx<T>

public final class HashFieldMapEx<T>
extends Object
implements FieldMapEx<T>

Forked and modified from protostuff Field mapping implemented on top of hash for field lookup by number. This is the less efficient than ArrayFieldMapEx 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.
