Method Detail

• getBooleanBuilder

  public ArrayBuilders.BooleanBuilder getBooleanBuilder()

• getByteBuilder

  public ArrayBuilders.ByteBuilder getByteBuilder()

• getShortBuilder

  public ArrayBuilders.ShortBuilder getShortBuilder()

• getIntBuilder

  public ArrayBuilders.IntBuilder getIntBuilder()

• getLongBuilder

  public ArrayBuilders.LongBuilder getLongBuilder()

• getFloatBuilder

  public ArrayBuilders.FloatBuilder getFloatBuilder()

• getDoubleBuilder

  public ArrayBuilders.DoubleBuilder getDoubleBuilder()

• getArrayComparator

  public static Object getArrayComparator(Object defaultValue)

  Helper method used for constructing simple value comparator used for comparing arrays for content equality.

  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).

  2.2 Moved from earlier Comparators class

• arrayToSet

  public static <T> HashSet<T> arrayToSet(T[] elements)

• arrayToList

  public static <T> ArrayList<T> arrayToList(T[] elements)

• setAndArray

  public static <T> HashSet<T> setAndArray(Set<T> set,
                           T[] elements)

• addToList

  public 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).

  Parameters:

  list - List to add to; may be null to indicate that a new List is to be constructed

  element - Element to add to list

  Returns:

  List in which element was added; either list (if it was not null), or a newly constructed List.

• insertInList

  public 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. No checking is done to see if element being inserted is duplicate.

• insertInListNoDup

  public 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. If element already existed, one of two things happens: if the element was already the first one in array, array is returned as is; but if not, a new copy is created in which element has moved as the head.

• arrayAsIterator

  public static <T> Iterator<T> arrayAsIterator(T[] array)

  Helper method for exposing contents of arrays using a read-only iterator

• arrayAsIterable

  public static <T> Iterable<T> arrayAsIterable(T[] array)
