interface method. Clients implementing this
method can be sure that the input object and eventually the subset information has already been set.
This method is called as a last step in the readProductNodes(input, subsetInfo)
method.

The destination band, buffer and region parameters are exactly the ones passed to the original call. Since
the destOffsetX
and destOffsetY
parameters are already taken into account in the
sourceOffsetX
and sourceOffsetY
parameters, an implementor of this method is free to
ignore them.

AbstractProductReader
This method should be called only if it is for sure that this object instance will never be used again. The
results of referencing an instance of this class after a call to close()
are undefined.
Overrides of this method should always call super.close();
after disposing this instance.
