Constructor Detail

AnonId

public AnonId()

Creates new AnonId. Normally this id is guaranteed to be unique on this machine: it is time-dependant. However, sometimes [incorrect] code is sensitive to bnode ordering and produces bizarre bugs (both Dave and Chris have been bitten by this, as have some users, I think). Hence the disableBNodeUIDGeneration flag, which allows bnode IDs to be predictable.
