String getHoverInfo(
ITextViewer textViewer,
                           
IRegion hoverRegion)
Deprecated. As of 3.4, replaced by ITextHoverExtension2.getHoverInfo2(ITextViewer, IRegion)

Returns the information which should be presented when a hover popup is shown for the specified hover region. The hover region has the same semantics as the region returned by getHoverRegion. If the returned information is null or empty no hover popup will be shown.

Specified by:
getHoverInfo in interface ITextHover
Parameters:
textViewer - the viewer on which the hover popup should be shown
hoverRegion - the text range in the viewer which is used to determine the hover display information
Returns:

ITextViewer textViewer,
                              int offset)
Description copied from interface: ITextHover
Returns the text region which should serve as the source of information to compute the hover popup display information. The popup has been requested for the given offset.

For example, if hover information can be provided on a per method basis in a source viewer, the offset should be used to find the enclosing method and the source range of the method should be returned.

Specified by:
getHoverRegion in interface ITextHover
Parameters:
textViewer - the viewer on which the hover popup should be shown
offset - the offset for which the hover request has been issued
Returns:
the hover region used to compute the hover display information

true if the annotation is included in the computation
