DAO Deleter

This DAO deleter calls the delete method of a DAO, using a entity bean from the bean context as parameter.

Configuration

Namespace: http://www.milyn.org/xsd/smooks/persistence-1.2.xsd
Element: deleter
Attributes:

• beanId : The id under which the entity bean is bound in the bean context. (required)
• deleteOnElement : The element selector to select the element when the delete should execute. (required)
• dao : The name of the DAO that will be used. If it is not set then the default DAO is used. (optional)
• name* : The name of the insert method. Depending of the adapter this can mean different things. For instance when using annotated DAO's you can name the methods and target them with this property, but when using the Ibatis adapter you set the id of the Ibatis statement in this attribute. (optional)
• deletedBeanId : The bean id under which the deleted bean will be stored. If not set then the deleted bean will not be stored in bean context. (optional)
• deleteBefore : If the deleter should execute on the 'before' event. (default: false)

* This attribute is not supported by all scribe adapters.
