Creates a copy of the current entity snapshot with an updated geometry.

Method Detail

getTimestamp

public OSHDBTimestamp getTimestamp()

The timestamp for which the snapshot of this data entity has been obtained.

Returns:

snapshot timestamp as an OSHDBTimestamp object

getGeometry

public org.locationtech.jts.geom.Geometry getGeometry()

The geometry of this entity at the snapshot's timestamp clipped to the requested area of interest.

Returns:

the geometry as a JTS Geometry

getGeometryUnclipped

public org.locationtech.jts.geom.Geometry getGeometryUnclipped()

The geometry of this entity at the snapshot's timestamp. This is the full (unclipped) geometry of the osm entity.

Returns:

the unclipped geometry of the osm entity snapshot as a JTS Geometry

getEntity

public OSMEntity getEntity()

The entity for which the snapshot has been obtained.

This is the (not deleted) version of a OSHEntity that was valid at the provided snapshot timestamp.

Returns:

the OSMEntity object of this snapshot

getOSHEntity

public OSHEntity getOSHEntity()

The (parent) osh entity of the osm entity for which the snapshot has been obtained.

Returns:

the OSHEntity object corresponding to this snapshot
