java.lang.Objectnom.tam.util.ArrayFuncs
public class ArrayFuncs
This is a package of static functions which perform computations on arrays. Generally these routines attempt to complete without throwing errors by ignoring data they cannot understand.

getBaseClass(java.lang.Object o)
This routine returns the base class of an object. |
static int |
getBaseLength(java.lang.Object o)
This routine returns the size of the base element of an array. |
static int[] |
getDimensions(java.lang.Object o)
Find the dimensions of an object. |
static void |
main(java.lang.String[] args)
Test and demonstrate the ArrayFuncs methods. |
static byte |
