Method Detail

• get

  public static <T> T get(Enumeration<T> e,
                          int index)

  Returns the index-th value in the Enumeration, throwing IndexOutOfBoundsException if there is no such element.

  The Enumeration is advanced to index (or to the end, if index exceeds the number of entries) as a side effect of this method.

  Type Parameters:

  T - the type of object in the Enumeration

  Parameters:

  e - the enumeration to get a value from

  index - the index to get

  Returns:

  the object at the specified index

  Throws:

  IndexOutOfBoundsException - if the index is invalid

  IllegalArgumentException - if the object type is invalid

  Since:

  4.1

• toList

  public static <E> List<E> toList(Enumeration<? extends E> enumeration)

  Creates a list based on an enumeration.

  As the enumeration is traversed, an ArrayList of its values is created. The new list is returned.

  Type Parameters:

  E - the element type

  Parameters:

  enumeration - the enumeration to traverse, which should not be null.

  Returns:

  a list containing all elements of the given enumeration

  Throws:

  NullPointerException - if the enumeration parameter is null.

• toList

  public static List<String> toList(StringTokenizer stringTokenizer)

  Override toList(Enumeration) for StringTokenizer as it implements Enumeration<Object> for the sake of backward compatibility.

  Parameters:

  stringTokenizer - the tokenizer to convert to a List< String>

  Returns:

  a list containing all tokens of the given StringTokenizer
