AccessCallback Contract for providing callback access to a DatabaseStructure, typically from the Optimizer
DatabaseStructure Encapsulates definition of the underlying data structure backing a sequence-style generator. 
Optimizer Performs optimization on an optimizable identifier generator. 
OptimizerFactory.InitialValueAwareOptimizer Marker interface for optimizer which wish to know the user-specified initial value. 


OptimizerFactory Factory for OptimizerFactory.InitialValueAwareOptimizer instances. 
OptimizerFactory.HiLoOptimizer Optimizer which applies a 'hilo' algorithm in memory to achieve optimization. 
OptimizerFactory.NoopOptimizer An optimizer that performs no optimization. 
OptimizerFactory.OptimizerSupport Common support for optimizer implementations. 
OptimizerFactory.PooledOptimizer Optimizer which uses a pool of values, storing the next low value of the range in the database. 
SequenceStructure Describes a sequence. 
SequenceStyleGenerator Generates identifier values based on an sequence-style database structure. 
TableGenerator An enhanced version of table-based id generation. 
TableStructure Describes a table used to mimic sequence behavior
