ObjectIdentifierGenerator

public ObjectIdentifierGenerator(int idLength)

Initialize the new instance with the length for the generated identifiers.

Parameters:

idLength - The length to which Ids are filled up with leading zeros (must be > 0)

ObjectIdentifierGenerator

public ObjectIdentifierGenerator(long startId,
                                 int idLength)

Initialize the new instance with the length for the generated identifiers and the id to start with.

Parameters:

startId - The first id to be generated.

idLength - The length to which Ids are filled up with leading zeros.
