public class OptimizerFactory
extends Object

Factory for Optimizer instances.

Nested Class Summary

static class	OptimizerFactory.HiLoOptimizer Optimizer which applies a 'hilo' algorithm in memory to achieve optimization.
static interface	OptimizerFactory.InitialValueAwareOptimizer Marker interface for optimizer which wish to know the user-specified initial value.
static class	OptimizerFactory.LegacyHiLoAlgorithmOptimizer
static class	OptimizerFactory.NoopOptimizer An optimizer that performs no optimization.
static class	OptimizerFactory.OptimizerSupport Common support for optimizer implementations.
static class	OptimizerFactory.PooledLoOptimizer
static class	OptimizerFactory.PooledOptimizer Optimizer which uses a pool of values, storing the next low value of the range in the database.
static class	OptimizerFactory.StandardOptimizerDescriptor

Field Summary

static String	HILO Deprecated. Use OptimizerFactory.StandardOptimizerDescriptor.getExternalName() via OptimizerFactory.StandardOptimizerDescriptor.HILO
static String	LEGACY_HILO Deprecated. Use OptimizerFactory.StandardOptimizerDescriptor.getExternalName() via OptimizerFactory.StandardOptimizerDescriptor.LEGACY_HILO
static String	NONE Deprecated. Use OptimizerFactory.StandardOptimizerDescriptor.getExternalName() via OptimizerFactory.StandardOptimizerDescriptor.NONE
static String	POOL Deprecated. Use OptimizerFactory.StandardOptimizerDescriptor.getExternalName() via OptimizerFactory.StandardOptimizerDescriptor.POOLED
