Enum Constant Detail

• ALWAYS_NULL

  public static final AccessPattern ALWAYS_NULL

  Value that indicates that provider never returns anything other than Java `null`.

• CONSTANT

  public static final AccessPattern CONSTANT

  Value that indicates that provider will always return a constant value, regardless of when it is called; and also that it never uses `context` argument (which may then be passed as `null`)

• DYNAMIC

  public static final AccessPattern DYNAMIC

  Value that indicates that provider may return different values at different times (often a freshly constructed empty container), and thus must be called every time "null replacement" value is needed.

Method Detail

• values

  public static AccessPattern[] 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 (AccessPattern c : AccessPattern.values())
      System.out.println(c);
  

  Returns:

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

• valueOf

  public static AccessPattern 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
