/**

 * Subclass of the {@link org.hibernate.id.enhanced.TableGenerator} for the sole purpose to

 * allow overriding the {@link org.hibernate.id.enhanced.TableGenerator#OPT_PARAM} and

 * {@link org.hibernate.id.enhanced.TableGenerator#INITIAL_PARAM} for the testing environment

 * (in principle you can override any of the TableGenerator parameters).

 * Test data may not always contain the hibernate sequences table which often leads to problems

 * with existing primary key values when inserting new entities. This especially occurs when

 * running test in a suite.

 * To circumvent these problems you can set a global override for the high initial parameter which

 * is far beyond any id ever used in test data sets.

 * You may want to set this in your testing application context, eg:

 *

 *<pre>

 * <bean id="tableGeneratorGlobalOverride" class="eu.etaxonomy.cdm.persistence.hibernate.TableGeneratorGlobalOverride">

 *          <property name="properties">

	*            <props>

	*				<!--

	*					globally overriding id generation settings

	*					see: eu.etaxonomy.cdm.persistence.hibernate.TableGenerator

	*				-->

	*				<prop key="optimizer">none</prop>

	*				<prop key="initial_value">1000</prop>

 *          	</props>

 *        </property>

 *  </bean>

 *</pre>

 *

 * If you set the optimizer to "none", hibernate will always query the database for each new id.

 * You must tell spring to instantiate the ... before the session factory:

 *

 * <pre>

 * <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean" depends-on="tableGeneratorGlobalOverride">

 * ...

 * </pre>

 *
