Class AbstractSpringSchemaUpdate<T>

java.lang.Object
  org.dellroad.stuff.schema.AbstractSchemaUpdate<T>
      org.dellroad.stuff.schema.AbstractSpringSchemaUpdate<T>

Type Parameters:

T - database transaction type

All Implemented Interfaces:

SchemaUpdate<T>, BeanFactoryAware, BeanNameAware, InitializingBean

Direct Known Subclasses:

SpringPersistentObjectSchemaUpdate, SpringSQLSchemaUpdate

public abstract class AbstractSpringSchemaUpdate<T>
extends AbstractSchemaUpdate<T>
implements BeanNameAware, BeanFactoryAware, InitializingBean

Support superclass for SchemaUpdates declared in Spring BeanFactorys that infer their names and required predecessors from their Spring bean attributes.

Instances infer their name and required predecessors from their Spring bean name (specified by the id XML attribute) and Spring dependencies (specified by the depends-on XML attribute), respectively.

Note: the use of depends-on is an abuse of Spring's dependency notation for convenience. Normally depends-on refers to bean intialization ordering, whereas this class uses it to refer to schema update ordering. Schema updates are not normally expected to have any initialization ordering requirements, so this abuse shouldn't matter. If they do, this class should not be used.

The containing BeanFactory must be a ConfigurableBeanFactory (normally this is always the case).
