org.apache.commons.collections.primitives.ArrayUnsignedShortList
public class ArrayUnsignedShortList
An IntList
backed by an array of unsigned
short
values.
This list stores int
values
in the range [
,
0
] in 16-bits
per element. Attempts to use elements outside this
range may cause an
65535
IllegalArgumentException
to be thrown.
