Other ones I'd expect an ArrayUtils to consider:
converting long[] to Long[] etc. Or List<Long>.
reversing an array. I think CollectionUtils currently has that.
some kind of 'map' method? So I would do:
ArrayUtils.map(array, function);
where function was defined as [one of your Pattern transformers?]
Interface Function:
Object eval(Object)
except it would automatically convert down to primitives etc.
Then there would be Matrix style methods:
flipMatrix(Object) which would take say a long[3][4] and convert it to
long[4][3]. Not sure that could be easy to do as it would have to handle
long[3][4][5] as well and stuff.
Would be a map method on the Matrix style arrays too. I forget the proper
name, nested arrays? double arrays? ack.
Other ones....
Maybe something to make copying an array easier.
public Object[] arraycopy(Object[]) or
public void arraycopy(Object[], Object[]) for when you want to do a plain
copy and not all the indexes.
Possibly a typed convert method.
So: public long[] toLongPrimitive(Long[]) so coders would do:
long[] lns =
ArrayUtils.toLongPrimitive((Long[])list.toArray(ArrayUtils.EMPTY_LONG));
ack. quite painful :)
S'all that springs to mind currently....
