Variation of PooledOptimizer which interprets the incoming database value as the lo value, rather than the hi value, as well as using thread local to cache the generation state.

public PooledLoThreadLocalOptimizer(Class<T> returnClass, int incrementSize)

Constructs a PooledLoThreadLocalOptimizer.

Parameters
returnClass:Class<T>

The Java type of the values to be generated

incrementSize:int

The increment size.

public boolean applyIncrementSizeToSourceValues()

Implements org.hibernate.id.enhanced.Optimizer.applyIncrementSizeToSourceValues.

Doc from org.hibernate.id.enhanced.Optimizer.applyIncrementSizeToSourceValues.

Are increments to be applied to the values stored in the underlying value source?

Returns:boolean

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.

public Serializable generate(AccessCallback callback)

Implements org.hibernate.id.enhanced.Optimizer.generate.

Doc from org.hibernate.id.enhanced.Optimizer.generate.

Generate an identifier value accounting for this specific optimization. All known implementors are synchronized. Consider carefully if a new implementation could drop this requirement.

Parameters
callback:AccessCallback

Callback to access the underlying value source.

Returns:Serializable

The generated identifier value.

getLastSourceValueback to summary
public IntegralDataTypeHolder getLastSourceValue()

Implements org.hibernate.id.enhanced.Optimizer.getLastSourceValue.

Doc from org.hibernate.id.enhanced.Optimizer.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.

Returns:IntegralDataTypeHolder

The last value we obtained from the underlying source; null indicates we have not yet consulted with the source.
