Class UploadSelectionAction.UploadHullBuilder

java.lang.Object
  org.openstreetmap.josm.actions.UploadSelectionAction.UploadHullBuilder

All Implemented Interfaces:

Visitor

Enclosing class:

UploadSelectionAction

static class UploadSelectionAction.UploadHullBuilder
extends java.lang.Object
implements Visitor

Computes the collection of primitives to upload, given a collection of candidate primitives. Some of the candidates are excluded, i.e. if they aren't modified. Other primitives are added. A typical case is a primitive which is new and and which is referred by a modified relation. In order to upload the relation the new primitive has to be uploaded as well, even if it isn't included in the list of candidate primitives.
