Note that if you create your array using the toArray() java function, you cannot use indexOf() java function anymore.

Ex.:

myArray = aQuery.aColumn.toArray(); // return you all rows corresponding to that column in an array.
findIt = myArray.indexOf('foo'); // Results in a crash -> method indexOf() not found.

Thanks Rupesh, I found that out yesterday. Using the code I originally posted, is there anyway to find the *first* index of a substring of an array using a "partial match" with these java utils?

That is what I am trying to accomplish. Using listtoarray() and listcontains() would be much slower.

Thanks again!

CV,
thats because "images" that you get from reMatchNoCase is an Array and it does not contain any element whose value is "_1thumb.jpg". Sure enough, there are elements in this array which contain this string, but indexof looks for the exact object.

If you need to get the count of elements that contain this string then, here is how you can modify the code

method="get">

",cfhttp.FileContent)>

#count#

Rupesh, please look at the simple code below. (Change < and > to get code to work.) I can never get a value greater than zero even though I should. Any ideas what I can do?

method="get">

",cfhttp.FileContent)>

#temp#

Here’s an alternate, fairly speedy one liner that returns true if two shorter lists have anything in common (case sensitive listreplacenocase is an alternative too):
{cfif listreplace(myfirst_list,mysecond_list,”*,*,…”) contains “*”}

One asterisk must exist in “*,*,…” for each mysecond_list element to be searched for.

Hey Rupesh, in late response to your response to my response (the util function to get object heirarchy) – I have modified the function and posted some results of it on my blog (has a link to this post):

http://fusion.dominicwatson.co.uk
(first ever post on it)

There is a little correction which I assume was a slip, it loops until the class is ‘java.lang.object’ and not ‘System.lang.Object’.

Definately prettier anyway, thanks!

Marco,
You figured out right that you have to use removeAll() to do this. Just wanted to make sure that this is how you are doing.

Some how I am not convinced that java gives a inconsistent result. Can you send me your sample code which can show inconsistent result? If it is a big file, you can mail it to me at rukumar at adobe.com

Rupesh, I'm using removeAll in arrays with more than 10 thousand elements. Java with big arrays works very unstable. For this example array1 haves 15000 elements and array2 15001 elements. Only 1 record in array2 doesn't match with array1. Please looks this simple code:
get Array size before removeAll
cfset arGetArquivosDir_Size = arGetArquivosDir.size()
cfset arArquivoIndice_Size = arArquivoIndice.size()
duplicate the final array - I'm using for the final removeAll
cfset arGetArquivosDir_Copia = Duplicate(arGetArquivosDir)

arGetArquivosDir_Copia: #arGetArquivosDir_Copia.size()# elements

remove elements in array1 matched with array2
cfset arGetArquivosDir.removeAll(arArquivoIndice)
vice versa
cfset arArquivoIndice.removeAll(arGetArquivosDir_Copia)

Using cfdump var="#arArquivoIndice#" should display only one record but after 2 tests look this dump:

TEST 1
arArquivoIndice - array
1 arArquivoIndice - struct
NAME 00000000000000122006070604.SGD

2 arArquivoIndice - struct
NAME 04025367000000162006070704.SGD

3 arArquivoIndice - struct
NAME 04025566000001132006070704.SGD

4 arArquivoIndice - struct
NAME 04026829000000742006071104.SGD

5 arArquivoIndice - struct
NAME 04027182000000112006071104.SGD

TEST 2
arArquivoIndice - array
1 arArquivoIndice - struct
NAME 00000000000000122006070604.SGD

2 arArquivoIndice - struct
NAME 04026827000000722006071104.SGD

3 arArquivoIndice - struct
NAME 04027172000000862006071104.SGD

4 arArquivoIndice - struct
NAME 04027180000000592006071104.SGD

5 arArquivoIndice - struct
NAME 04027415000000172006071204.SGD

Please look that 2 different results.

Rupesh, thank you. Great! Only one challenge to you: how to compare 2 arrays and display the differences between? Looks like this:
arrayTest1
1 struct
NAME 01076354000000012006071101.BAA

arrayTest2
1 struct
NAME 0107635400000002200607110A.BAA

arrayTest1 haves 100 elements and arrayTest2 103 elements. I'll want to display all elements that exist in arrayTest1 and not exist in ArrayTest2 and vice versa. Impossible?

Thanks Dominic. Nice util function to get object hierarchy. I would suggest a small enhancement in it. Instead of depending on exception for breaking out of the while loop, you can loop until your super class name is “System.lang.Object”. Thats because all the java objects extend from java.lang.Object.

Cheers,
Rupesh
