Returns an array containing the attribute names of the receiver’s values.

Returns:

  • (Array)

    An array containing the attribute names of the receiver’s values. See the “Constants” section for a list of possible keys.

- (Object) valueForAttribute(key)

Returns the receiver’s metadata attribute name specified by a given key.

Parameters:

  • key (String)

    The name of a metadata attribute. See the “Constants” section for a list of possible keys.

Returns:
