array manipulation
Apr 25th, 2005, 5:40pm  
these things can be handled by System.arraycopy, but could be nice if there were more array manipulation options available in processing, such as copying portions of arrays and searching arrays for values (like indexOf()).

though the latter is probably better left as something people can learn to program with loops, the former could be handy for those not aware of System.arraycopy.

nope, where are those?  can't find em in reference, online or off, nor in revisions...

splice, subset, and sort all sound like what i was thinking.  creating subsets is what caused this post in the first place.

oops, found em, in the 'complete' reference.

how bout that, i didn't even realize there was a 'complete' reference until now...i understand the desire to keep things simple for the beginners, but perhaps there is a way to make the complete reference more noticable?  maybe just in the reference title image - instead of "Language (API)", do like you do in the title tag, "Abridged Language" and "Complete Language".

wow.  i didn't realize how extensive the reference was getting!  good work, casey...

oop.  just tried to use the new array functions, but found that they only work with built-in datatypes.

i can just use java.util.ArrayList ( http://java.sun.com/j2se/1.4.2/docs/api/java/util/ArrayList.html ), but are there plans for these functions to be applicable to custom datatypes?

yeah, working on getting versions for custom datatypes in there as well, just ran out of time to finish for beta.

ArrayList will require that anyone using your work has java 1.2+, which is a current requirement for processing but will go away.

I notice that you can't currently append an array to a two dimensional array (no applicable overload). Will that come along with the custom data types?

i think we're gonna stay away from the 2+ dimensional stuff since it gets pretty messy from there. it's possible they'll sort of work, will have to see the mechanics once they're finished.
