                                           ProgressMonitor monitor)

Constructor

Parameters:

newLayer - if the data should be downloaded into a new layer

ids - List of primitive id to download

downloadReferrers - if the referrers of the object should be downloaded as well, i.e., parent relations, and for nodes, additionally, parent ways

full - if the members of a relation should be downloaded as well

monitor - ProgressMonitor to use, or null to create a new one

public java.util.List<PrimitiveId> getDownloadedId()

Return id of really downloaded primitives.

Returns:

List of primitives id or null if no primitives was downloaded
