String	getAltText() This method gets the alternative text of this object.

Method Detail

getAltText

String getAltText()

This method gets the alternative text of this object. This text is used to provide the essential information of an object in textual form. E.g. if an image can NOT be displayed because it is missing, the alternative text is displayed instead. Further, accessibility tools such as screen-readers can use this information to help the user in order to better understand the meaning of an object.

Returns:

the alternative text or null if NOT set.
