Method Detail

  public static <A> Argument<A> argument(A value)

  Factory method for arguments. Creates an argument by taking a value and determining the type of the given value.

  Type Parameters:

  A - the type of the argument.

  Parameters:

  value - the value to be wrapped by the new argument object. Must not be null! If you want to create a null argument use nullArgument(Class) instead.

  Returns:

  a new argument of type value.getClass()

• nullArgument

  public static <A> Argument<A> nullArgument(Class<A> type)

  Creates a new null argument of the given type. Shortcut for argument( type, null ).

  Parameters:

  type - the type of the new argument. Must not be null!

• argument

  public static <T,V extends T> Argument<T> argument(Class<T> type,
                                     V value)

  Creates a new argument of the given type with the given value.

  Type Parameters:

  T - the type of the argument.

  V - the type of the value of the argument.

  Parameters:

  type - the type of the new argument. Must not be null!

  value - the value of the new argument.

  Returns:

  a new argument of the given type with the given value.

• getType

  public Class<T> getType()

  Returns the argument's type. Note that the type returned maybe a super type of the actual type of the value returned by getValue() depending on how the argument was created. For example:
  argument( Number.class, Integer.valueOf( 4 ) );
  will create an argument with an Integer as Value but Number.class as type.

  Returns:

  the argument's type

• getValue

  public T getValue()

  Returns the value of the argument. Maybe null if this is a null argument.

  Returns:

  the value of the argument.
