SVGNumberList Interface
The SVGNumberList defines a list of SVGNumber
objects.
An SVGNumberList object can be designated as read only, which means that attempts to modify the object will result in an exception being thrown.
Starting in Gecko 5.0 (Firefox 5.0 / Thunderbird 5.0 / SeaMonkey 2.2)
,the SVGNumberList DOM interface is now indexable and can be accessed like arrays
Methods
Code SVGNumber appendItem(SVGNumber item) #
Inserts a new item at the end of the list. If newItem is already in a list, it is removed from its previous list before it is inserted into this list. The inserted item is the item itself and not a copy.
Exceptions:
- a
DOMExceptionwith codeNO_MODIFICATION_ALLOWED_ERRis raised when the list corresponds to a read only attribute or when the object itself is read only.
SVGNumber appendItem(SVGNumber item);
Code void clear() #
Clears all existing current items from the list, with the result being an empty list.
Exceptions:
- a
DOMExceptionwith codeNO_MODIFICATION_ALLOWED_ERRis raised when the list corresponds to a read only attribute or when the object itself is read only.
void clear();
Code SVGNumber getItem(int index) #
Returns the specified item from the list. The returned item is the item itself and not a copy. Any changes made to the item are immediately reflected in the list. The first item is number 0.
Exceptions:
- a
DOMExceptionwith codeNO_MODIFICATION_ALLOWED_ERRis raised when the list corresponds to a read only attribute or when the object itself is read only.
SVGNumber getItem(int index);
Code SVGNumber initialize(SVGNumber item) #
Clears all existing current items from the list and re-initializes the list to hold the single item specified by the parameter. If the inserted item is already in a list, it is removed from its previous list before it is inserted into this list. The inserted item is the item itself and not a copy. The return value is the item inserted into the list.
Exceptions:
- a
DOMExceptionwith codeNO_MODIFICATION_ALLOWED_ERRis raised when the list corresponds to a read only attribute or when the object itself is read only.
SVGNumber initialize(SVGNumber item);
Code SVGNumber insertItemBefore(SVGNumber item, int index) #
Inserts a new item into the list at the specified position. The first item is number 0. If newItem is already in a list, it is removed from its previous list before it is inserted into this list. The inserted item is the item itself and not a copy. If the item is already in this list, note that the index of the item to insert before is before the removal of the item. If the index is equal to 0, then the new item is inserted at the front of the list. If the index is greater than or equal to numberOfItems, then the new item is appended to the end of the list.
Exceptions:
- a
DOMExceptionwith codeNO_MODIFICATION_ALLOWED_ERRis raised when the list corresponds to a read only attribute or when the object itself is read only.
SVGNumber insertItemBefore(SVGNumber item, int index);
Code SVGNumber removeItem(int index) #
Removes an existing item from the list.
Exceptions:
- a
DOMExceptionwith codeNO_MODIFICATION_ALLOWED_ERRis raised when the list corresponds to a read only attribute or when the object itself is read only. - a
DOMExceptionwith codeINDEX_SIZE_ERRis raised if the index number is greater than or equal tonumberOfItems.
SVGNumber removeItem(int index);
Code SVGNumber replaceItem(SVGNumber item, int index) #
Replaces an existing item in the list with a new item. If newItem is already in a list, it is removed from its previous list before it is inserted into this list. The inserted item is the item itself and not a copy. If the item is already in this list, note that the index of the item to replace is before the removal of the item.
Exceptions:
- a
DOMExceptionwith codeNO_MODIFICATION_ALLOWED_ERRis raised when the list corresponds to a read only attribute or when the object itself is read only. - a
DOMExceptionwith codeINDEX_SIZE_ERRis raised if the index number is greater than or equal tonumberOfItems.
SVGNumber replaceItem(SVGNumber item, int index);
