Converting string to char array

[Andrew Dixon]

Hi,

I have a string that I need to convert to a char array to pass to a Java object, so if I do this manually I have to do:

exampleVar = javaCast("char[]", ['e','x','a','m','p','l','e']);

However I have the data as a string:

exampleVar = "example";

I've looked over the functions on the luceedocs.org but I can't see one for converting the string to an array, am I missing it or will I have to write a function myself to do this?

So I'm guessing I'm hoping for something like:

exampleVar = "example";

exampleStringArray = stringToArray(exampleVar);

exampleCharArray = javaCast("char[]", exampleStringArray);

Thanks.

Kind regards,

Andrew

You don't need a special Lucee function; there's already one in java.lang.String:

exampleVar = "example"

charArray = exampleVar.toCharArray()

dump(variables)

If - for some reason - you wanted to stick with CML:

cfmlArray =  exampleVar.listToArray("")

But use the toCharArray() version, IMO

as Adam said, we could also extend the function JavaCast to support this

carr = javaCast("char[]", "Hello World");

can you raise a ticket for it

Hi Micha,

That would be very useful, I have raised an issue as requested:

https://bitbucket.org/lucee/lucee/issue/284/extend-the-function-javacast-to-support

Any chance of getting this in 4.5?

Kind regards,

Andrew

I think this is a good tweak to javaCast(). But given you've been given two completely workable solutions that are already there in 4.5, what's the compelling reason to back port it into 4.5? (or, indeed, even specifically prioritise it for 5.0).

Hi Adam,

I guess not, just the code will be going onto a 4.5 production server that will probably not be updated to 5 anytime in the next 3 - 6 months, so it would say going back and changing the code if it was already available, but there is no compelling reason... I did load it into BitBucket as "minor"... :-)

Kind regards,

Andrew

normally we have the rule that we only do new features with alpha releases, so this means Lucee>5, but i think it is possible to thread this as a bug...
