Interface TemporaryIdSupplierI

All Superinterfaces:

java.io.Serializable

All Known Subinterfaces:

BackendSessionI

All Known Implementing Classes:

AbstractBackendSession, BackendSession, TemporaryIdSupplier

public interface TemporaryIdSupplierI
extends java.io.Serializable

Classes implementing this interface may be used for supplying temporary Ids for a Transaction instead of the Transaction managing that on its own. The contract for temporary Ids is that they are unique and negative. If an instance is shared among multiple Transactions, access to #next should of course be synchronized in some fashion (e.g. using an AtomicLong internally).
