org.hibernate.id.enhanced.OptimizerFactory.NoopOptimizer

All Implemented Interfaces:

Optimizer

Enclosing class:

OptimizerFactory

public static final class OptimizerFactory.NoopOptimizer
extends OptimizerFactory.OptimizerSupport

An optimizer that performs no optimization. The database is hit for every request. Using this implementation is probably not the most efficient choice.

Method Detail

generate

public Serializable generate(AccessCallback callback)

Description copied from interface: Optimizer

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 - Callback to access the underlying value source.

Returns:

The generated identifier value.

getLastSourceValue

public IntegralDataTypeHolder getLastSourceValue()

Description copied from interface: Optimizer

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:

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

applyIncrementSizeToSourceValues

public boolean applyIncrementSizeToSourceValues()

Description copied from interface: Optimizer

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

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.
