org.apache.commons.collections.primitives.ArrayUnsignedByteList
public class ArrayUnsignedByteList
A ShortList
backed by an array of unsigned
byte
values.
This list stores short
values
in the range [MIN_VALUE
,
MAX_VALUE
] in 8-bits
per element. Attempts to use elements outside this
range may cause an
IllegalArgumentException
to be thrown.
