Description Stephan Leicht Vogt CLA 2010-12-17 04:58:17 EST 
As stated in the Forum-Message <http://www.eclipse.org/forums/index.php?t=msg&th=201998&start=0&S=be81068d90b5b6b0945dc5560a882115> it would be useful if there would be also an save way to get the size of an array like it allready exists for Strings.

Example:
int size = ListUtility.size(someByte[]); (someByte[] can be null)
Comment 1 Ivan Motsch CLA 2010-12-23 08:19:34 EST 
This will be added for the June 2011 release either in ListUtility, CollectionUtility or ArrayUtility
Comment 2 Ivan Motsch CLA 2011-05-02 10:07:58 EDT 
Done as ListUtility.length.

junit test:
    assertEquals(-1, ListUtility.length(null));
    assertEquals(3, ListUtility.length(new int[3]));
    assertEquals(3, ListUtility.length(new int[3][4]));
    assertEquals(3, ListUtility.length(new String[3]));
    assertEquals(3, ListUtility.length(new String[3][4]));
    assertEquals(3, ListUtility.length(new ArrayList<String>(Arrays.asList(new String[]{"a", "b", "c"}))));
    assertEquals(0, ListUtility.length(new HashMap<String, String>()));
Comment 3 Matthias Zimmermann CLA 2011-06-28 08:04:22 EDT 
shipped with eclipse scout 3.7.0
