Class ShortImmutableList
- All Implemented Interfaces:
ShortCollection,ShortIterable,ShortList,ShortStack,Stack<Short>,Serializable,Cloneable,Comparable<List<? extends Short>>,Iterable<Short>,Collection<Short>,List<Short>,RandomAccess,SequencedCollection<Short>
Instances of this class are immutable and (contrarily to mutable array-based list implementations) the backing array is not exposed. Instances can be built using a variety of methods, but note that constructors using an array will not make a defensive copy.
This class implements the bulk method getElements() using high-performance system calls
(e.g., System.arraycopy()) instead of
expensive loops.
