HistoryOsmPrimitive

protected HistoryOsmPrimitive(long id,
                              long version,
                              boolean visible,

                              java.time.Instant timestamp)

Constructs a new HistoryOsmPrimitive.

Parameters:

id - the id (> 0 required)

version - the version (> 0 required)

visible - whether the primitive is still visible

user - the user (!= null required)

changesetId - the changeset id (> 0 required)

timestamp - the timestamp (!= null required)

Throws:

java.lang.IllegalArgumentException - if preconditions are violated

HistoryOsmPrimitive

protected HistoryOsmPrimitive(long id,
                              long version,

                              boolean checkHistoricParams)

Constructs a new HistoryOsmPrimitive with a configurable checking of historic parameters. This is needed to build virtual HistoryOsmPrimitives for modified primitives, which do not have a timestamp and a changeset id.

Parameters:

id - the id (> 0 required)

version - the version (> 0 required)

visible - whether the primitive is still visible

user - the user (!= null required)

changesetId - the changeset id (> 0 required if checkHistoricParams is true)

timestamp - the timestamp (!= null required if checkHistoricParams is true)

checkHistoricParams - if true, checks values of changesetId and timestamp

Throws:

java.lang.IllegalArgumentException - if preconditions are violated
