Description:SignedWordArrays store 16bit signed integers in the range 16r-8000..16r7FFF. They are much like WordArrays, but the values stored are signed. In contrast to normal arrays (which store pointers to their elements), signedWordArrays store the values in a dense & compact way. Since the representation fits the underlying C-language systems representation of signed int16's, this is also useful to pass bulk data to c primitive code. Therefore, SignedWordArrays can be used to hold bulk data in a more compact way. For example: Array new:100000 withAll:1 requires 400k of object memory; in contrast, SignedWordArray new:100000 withAll:1 only requires half of it. [memory requirements:] OBJ-HEADER + (size * 2) [caveat:] should probably be renamed to SignedInt16Array Related information:ByteArray WordArray BooleanArray FloatArray DoubleArray Array IntegerArray LongIntegerArray SignedLongIntegerArray Class protocol:queries
