static <T> List<T> |
addToList(List<T> list,
T element)
Helper method for adding specified element to a List, but also
considering case where the List may not have been yet constructed
(that is, null is passed instead).
|
static <T> ArrayList<T> |
arrayToList(T[] elements) |
static <T> HashSet<T> |
arrayToSet(T[] elements) |
static Object |
getArrayComparator(Object defaultValue)
Helper method used for constructing simple value comparator used for
comparing arrays for content equality.

static <T> T[] |
insertInList(T[] array,
T element)
Helper method for constructing a new array that contains specified
element followed by contents of the given array.
|
static <T> T[] |
insertInListNoDup(T[] array,
T element)
Helper method for constructing a new array that contains specified
element followed by contents of the given array but never contains
duplicates.

T[] elements) |

Note: current implementation is not optimized for speed; if performance ever becomes an issue, it is possible to construct much more efficient typed instances (one for Object[] and sub-types; one per primitive type).
