Utility methods for working with arrays.

Method Summary

Modifier and Type	Method	Description
`static float[][]`	`clone(float[][] array)`	Clones a two dimensional array of floats.
`static int`	`compareVersionArrays(Comparable[] a1, Comparable[] a2)`	Compares the initial elements of two arrays.
`static boolean`	`equal(float[][] array1, float[][] array2)`	Tests two float arrays for equality.
`static boolean`	`equalReferencesInArrays(Object[] array1, Object[] array2)`	Returns `true` if all the references in `array1` are equal to all the references in `array2` (two `null` references are considered equal for this test).
`static boolean`	`hasDuplicateItems(Object[] array)`	Returns `true` if any two items in the array are equal to one another.

Method Details
- clone
  
  public static float[][] clone(float[][] array)
  
  Clones a two dimensional array of floats.
  
  Parameters:
  
  array - the array.
  
  Returns:
  
  A clone of the array.
- equalReferencesInArrays
  
  public static boolean equalReferencesInArrays(Object[] array1, Object[] array2)
  
  Returns true if all the references in array1 are equal to all the references in array2 (two null references are considered equal for this test).
  
  Parameters:
  
  array1 - the first array (null permitted).
  
  array2 - the second array (null permitted).
  
  Returns:
  
  A boolean.
- equal
  
  public static boolean equal(float[][] array1, float[][] array2)
  
  Tests two float arrays for equality.
  
  Parameters:
  
  array1 - the first array (null permitted).
  
  array2 - the second arrray (null permitted).
  
  Returns:
  
  A boolean.
- hasDuplicateItems
  
  public static boolean hasDuplicateItems(Object[] array)
  
  Returns true if any two items in the array are equal to one another. Any null values in the array are ignored.
  
  Parameters:
  
  array - the array to check.
  
  Returns:
  
  A boolean.
- compareVersionArrays
  
  public static int compareVersionArrays(Comparable[] a1, Comparable[] a2)
  
  Compares the initial elements of two arrays.
  
  Parameters:
  
  a1 - array 1.
  
  a2 - array 2.
  
  Returns:
  
  An integer showing the relative ordering.
