This class extends DataBuffer and stores data internally as shorts. Values stored in the short array(s) of this DataBuffer are treated as unsigned values.
Note that some implementations may function more efficiently if they can maintain control over how the data for an image is stored. For example, optimizations such as caching an image in video memory require that the implementation track all modifications to that data. Other implementations may operate better if they can store the data in locations other than a Java array. To maintain optimum compatibility with various optimizations it is best to avoid constructors and methods which expose the underlying storage as a Java array as noted below in the documentation for those methods.

(->data-buffer-u-short size)
(->data-buffer-u-short size num-banks)
(->data-buffer-u-short data-array size offset)
Constructor.
Constructs an unsigned-short based DataBuffer with a single bank using the specified array, size, and offset. dataArray must have at least offset size elements. Only elements offset through offset size - 1 should be used by accessors of this DataBuffer.
Note that DataBuffer objects created by this constructor may be incompatible with performance optimizations used by some implementations (such as caching an associated image in video memory).
data-array - The unsigned-short array for the DataBuffer. - short[]
size - The size of the DataBuffer bank. - int
offset - The offset into the dataArray. - int
