org.locationtech.jts.geom.Geometry	edit(org.locationtech.jts.geom.Geometry geometryWithSelectedItems, Collection<org.locationtech.jts.geom.Geometry> selectedItems)	selectedItems may have the whole geometry, parts (collection elements), or linestrings, or a mix of all three.

Method Details

edit

org.locationtech.jts.geom.Geometry edit(org.locationtech.jts.geom.Geometry geometryWithSelectedItems,
 Collection<org.locationtech.jts.geom.Geometry> selectedItems)

selectedItems may have the whole geometry, parts (collection elements), or linestrings, or a mix of all three. But there will be no duplicate data (that is, you can't select both the whole and one of its parts -- only the whole geometry will be selected; similarly, you can't select a part and one of its linestrings -- only the part will be selected).

Parameters:

geometryWithSelectedItems - a clone of the geometry containing the selected items. Because geometryWithSelectedItems is a clone, feel free to modify it, as no other parties reference it. Then return it (or return something totally different).

selectedItems - clones of the selected items (each of which have class Geometry). selectedItems' elements are "live"; that is, they are objects taken from geometryWithSelectedItems. So, for example, modifying selectedItem's coordinates will modify geometryWithSelectedItems' coordinates.

Returns:

a new Geometry for the Feature (typically geometryWithSelectedItems, but can be a completely different Geometry), or an empty geometry to (undoably) remove the Feature from the Layer
