[gdal-dev] Java binding gdal.AutoCreateWarpedVRT question

[Chaitanya kumar CH]

Billy,

The returned dataset is a virtual dataset handle that has to be closed
after it is used.
But keep in mind that the returned dataset will acquire one or more
references of the original dataset. So, unless it is opened with
GDALOpenShared(), it's not a good idea to close the original dataset before
closing the warped dataset.
