Re: [Vtd-xml-users] Random Access Proposal (take 2)

[Jimmy Z. <cra...@co...>]

setCursorPosition() and getCursroPosition() have been added in CVS

but the benefit of unbind() is still not clear

if GC of VTDnav is the goal then one can simply call "setCursorPosition()" 
on
a different VTDNav object and the mission is accomplished without having a
unbind method for bookMark...
