Gets or sets a string which represents the hyperlink for this AnnObject.
Object.defineProperty(AnnObject.prototype, 'hyperlink',
get: function(),
set: function(value)
)
hyperlink: string;
The hyperlink for this AnnObject. The default value is null.
The hyperlink of an object can be any string value or null. It is up to the user's application to determine how to use this value.
This example will create two annotation objects with hyperlinks and add them to a container, switches to run mode and run the hyperlink when the object is clicked.
