Interface PMap<K,V>

Type Parameters:

K -

V -

All Superinterfaces:

Map<K,V>

All Known Subinterfaces:

PSortedMap<K,V>

All Known Implementing Classes:

public interface PMap<K,V>
extends Map<K,V>

An immutable, persistent map from keys of type K to values of type V.

Some implementations may not support null keys and/or values, in which case they will throw NullPointerException for attempts to add such keys/values.
