OptimizerFactory.PooledOptimizer (Hibernate Core Aggregator 3.6.10.Final API)

java.lang.Object
- org.hibernate.id.enhanced.OptimizerFactory.OptimizerSupport
- - org.hibernate.id.enhanced.OptimizerFactory.PooledOptimizer

All Implemented Interfaces:

Optimizer, OptimizerFactory.InitialValueAwareOptimizer

Enclosing class:

OptimizerFactory
```
public static class OptimizerFactory.PooledOptimizer
extends OptimizerFactory.OptimizerSupport
implements OptimizerFactory.InitialValueAwareOptimizer
```
Optimizer which uses a pool of values, storing the next low value of the range in the database.
Note that this optimizer works essentially the same as the OptimizerFactory.HiLoOptimizer except that here the bucket ranges are actually encoded into the database structures.
Note if you prefer that the database value be interpreted as the bottom end of our current range, then use the OptimizerFactory.PooledLoOptimizer strategy

                                int incrementSize)
```
- Method Detail
  - generate
```
public Serializable generate(AccessCallback callback)
```
    Generate an identifier value accounting for this specific optimization.
    
    Specified by:
    
    generate in interface Optimizer
    
    Parameters:
    callback - Callback to access the underlying value source.
    
    Returns:
    The generated identifier value.
  - getLastSourceValue
```
public IntegralDataTypeHolder getLastSourceValue()
```
    A common means to access the last value obtained from the underlying source. This is intended for testing purposes, since accessing the underlying database source directly is much more difficult.
    
    Specified by:
    
    getLastSourceValue in interface Optimizer
    
    Returns:
    The last value we obtained from the underlying source; null indicates we have not yet consulted with the source.
  - applyIncrementSizeToSourceValues
```
public boolean applyIncrementSizeToSourceValues()
```
    Are increments to be applied to the values stored in the underlying value source?
    
    Specified by:
    
    applyIncrementSizeToSourceValues in interface Optimizer
    
    Returns:
    True if the values in the source are to be incremented according to the defined increment size; false otherwise, in which case the increment is totally an in memory construct.
  - getLastValue
```
public IntegralDataTypeHolder getLastValue()
```
    Getter for property 'lastValue'.
    Exposure intended for testing purposes.
    
    Returns:
    Value for property 'lastValue'.
  - injectInitialValue
```
public void injectInitialValue(long initialValue)
```
    Reports the user specified initial value to the optimizer.
    -1 is used to indicate that the user did not specify.
    
    Specified by:
    
    injectInitialValue in interface OptimizerFactory.InitialValueAwareOptimizer
    
    Parameters:
    initialValue - The initial value specified by the user, or -1 to indicate that the user did not specify.
