T
- the type of the field elementspublic class OpenIntToFieldHashMap<T extends FieldElement<T>>
extends java.lang.Object
implements java.io.Serializable
This class provides a dedicated map from integers to FieldElements with a
much smaller memory overhead than standard java.util.Map
.
This class is not synchronized. The specialized iterators returned by
iterator()
are fail-fast: they throw a
ConcurrentModificationException
when they detect the map has been
modified during iteration.
