Description:

An abstract superclass for all unboxed integer classes.
In contrast to normal arrays (which store pointers to their elements),
unboxedIntegerArrays store the values in a dense & compact way. 
Since the representation fits corresponding underlying C-language representations,
these are also useful to pass bulk data to/from C primitive code.

Class protocol:

 new: size elementBitSize: nBitsPerElement signed: signedBoolean

return a new instance for size elements,
each holding an nBitsPerElement-sized integer.
With nBitsPerElement == 8, this returns a byteArray/signedByteArray,
with nBitsPerElement == 16, a word/signedWordArray
with nBitsPerElement == 32, an integer/signedIntegerArray
and with nBitsPerElement == 65, a longInteger/signedLongIntegerArray
Other sizes might be provided in the future.

Usage example(s):

self new:10 elementBitSize:8 signed:false self new:10 elementBitSize:8 signed:true self new:10 elementBitSize:16 signed:true self new:10 elementBitSize:64 signed:true

 isAbstract

Return if this class is an abstract class.
True is returned for UnboxedIntegerArray here; false for subclasses.
Abstract subclasses must redefine this again.

 isValidElement: anObject

return true, if instances of me can hold this kind of object

Instance protocol:

 printOn: aStream base: radix showRadix: showRadix

append a printed representation to aStream in the given number base.

 defaultElement

 isIntegerArray

return true if the receiver has integer elements.
These are Byte- and Integer arrays; both signed and unsigned
