Examples of org.milyn.javabean.repository.BeanId

org.milyn.javabean.repository.BeanId
Bean Id
The BeanId represents the id of a bean. It is used to set and retrieve instance of the bean from the BeanRepository.
The String representation of the BeanId is registered with a {@link BeanIdRegister}and there by coupled to that {@link BeanIdRegister}. The BeanId holds the original {@link String} beanId,also called beanIdName. It also holds the index ofthe place it has within the {@link BeanIdRegister}. @author maurice.zeijen@smies.com
