| [[Category:UnicodeNamedArraylist methods|ItemByNumber property]] | |
| <!--DPL?? Category:UnicodeNamedArraylist methods|ItemByNumber property: Value of item selected by it-->
| |
| <p>
| |
| ItemByNumber is a member of the [[UnicodeNamedArraylist class]].
| |
| </p>
| |
| | |
| This ReadWrite property returns or sets the UnicodeNamedArraylist item that has
| |
| the specified item number.
| |
| Item number is ordinal, so
| |
| ItemByNumber(3), for example, identifies the third item in the
| |
| ordered-by-name UnicodeNamedArraylist.
| |
| ==Syntax==
| |
| %item = %unamrayl:ItemByNumber(number)
| |
| | |
| %unamrayl:ItemByNumber(number) = %item
| |
| ===Syntax Terms===
| |
| <dl>
| |
| <dt><i>%item</i>
| |
| <dd>A variable of the same
| |
| type as specified on the ''%unamrayl'' declaration
| |
| to contain the value of the specified ''%unamrayl'' item.
| |
| Or a variable or value of the same
| |
| type as specified on the ''%unamrayl'' declaration
| |
| to be assigned to the specified ''%unamrayl'' item.
| |
| <dt><i>%unamrayl</i>
| |
| <dd>A UnicodeNamedArraylist object.
| |
| <dt><i>number</i>
| |
| <dd>A whole number greater than 0 to identify a ''%unamrayl'' item
| |
| by its position in the UnicodeNamedArraylist.
| |
| If ''number'' is greater than the number of items in ''%unamrayl'',
| |
| or if it is less than or equal to zero, the request is cancelled.
| |
| | |
| </dl>
| |
| ==Usage Notes==
| |
| <ul>
| |
| <li>If the ItemByNumber property is being set and there is already an item
| |
| on the UnicodeNamedArraylist that has the specified item number (position),
| |
| that item is replaced.
| |
| | |
| If the ItemByNumber property is being set and there is no item on the
| |
| UnicodeNamedArraylist that has the indicated item number, the item is added.
| |
| | |
| If the ItemByNumber property is being retrieved and there is no item on the
| |
| UnicodeNamedArraylist that has the indicated item number,
| |
| the result is one of the following actions:
| |
| <ul>
| |
| <li>The request is cancelled if the
| |
| [[UseDefault (UnicodeNamedArraylist property)|UseDefault]] property value is <tt>False</tt>.
| |
| <li>The [[Default (UnicodeNamedArraylist property)|Default]] value is returned if the
| |
| UseDefault property is <tt>True</tt>.
| |
| </ul>
| |
| <li>[[Item (UnicodeNamedArraylist property)|Item]] lets you retrieve or
| |
| set an item using its item name.
| |
| <li>For an example using the ItemByNumber method, see [[UnicodeNamedArraylist class]].
| |
| </ul>
