Attributes

 The numbber of anchors within this Hyperlink. Is normally 1 for anchors.
 This anchor is, for example, the visible output of the html:a tag.
 With an Image Map, reflects the actual areas within the map.

readonly attribute long anchorCount

 Returns the end index of the link within the parent accessible.

 @note  The link itself is represented by one embedded character within the
 parent text, so the endIndex should be startIndex + 1.

readonly attribute long endIndex

 Determines whether the element currently has the focus, e. g. after
 returning from the destination page.

 @note  ARIA links can only be focused if they have the tabindex
 attribute set.  Also, state_focused should then be set on the accessible
 for this link.

readonly attribute boolean selected

 Returns the offset of the link within the parent accessible.

readonly attribute long startIndex

 Determines whether the link is valid (e. g. points to a valid URL).

 @note  XXX Currently only used with ARIA links, and the author has to
 specify that the link is invalid via the aria-invalid="true" attribute.
 In all other cases, TRUE is returned.

readonly attribute boolean valid

Methods

 Returns a reference to the object at the given index.

 @param index  The 0-based index whose object is to be returned.

 @return the nsIAccessible object at the desired index.

nsIAccessible getAnchor(in long index)

 Returns the URI at the given index.

 @note  ARIA hyperlinks do not have an URI to point to, since clicks are
 processed via JavaScript. Therefore this property does not work on ARIA
 links.

 @param index  The 0-based index of the URI to be returned.

 @return the nsIURI object containing the specifications for the URI.
