Method Detail

• values

  public static CollectionUtils[] values()

  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

  for (CollectionUtils c : CollectionUtils.values())
      System.out.println(c);
  

  Returns:

  an array containing the constants of this enum type, in the order they are declared

• valueOf

  public static CollectionUtils valueOf(String name)

  Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

  Parameters:

  name - the name of the enum constant to be returned.

  Returns:

  the enum constant with the specified name

  Throws:

  IllegalArgumentException - if this enum type has no constant with the specified name

  NullPointerException - if the argument is null
