Class AnnotationBringBeanRegistry

java.lang.Object

com.bobocode.bring.core.context.impl.DefaultBringBeanFactory

com.bobocode.bring.core.context.impl.AnnotationBringBeanRegistry

All Implemented Interfaces:

BeanDefinitionRegistry, BeanRegistry, BringBeanFactory

Direct Known Subclasses:

BringApplicationContext

public class AnnotationBringBeanRegistry
extends DefaultBringBeanFactory
implements BeanRegistry, BeanDefinitionRegistry

Registry class responsible for:

1. Registering beans by bean name and bean definition: The bean name is created using AnnotationResolver and is the key of the DefaultBringBeanFactory.beanDefinitionMap. The bean definition contains all the necessary information that is needed to create a bean. Depending on the bean scope, an object or a supplier will be stored in the application context.
2. Registering bean definitions: storing bean definitions in DefaultBringBeanFactory.beanDefinitionMap. Those will be used in the future to create or retrieve beans.

Method Details

registerBean

public void registerBean(String beanName,
 BeanDefinition beanDefinition)

Registers beans in the application context. Creates and stores singleton bean objects or suppliers for prototype beans. Also defines the proper way to create beans depending on the type of the bean (annotated class or configuration bean) and injects dependant beans.

Specified by:

registerBean in interface BeanRegistry

Parameters:

beanName - The name of the bean to be registered.

beanDefinition - The definition of the bean being registered.

registerBeanDefinition

public void registerBeanDefinition(BeanDefinition beanDefinition)

Stores a bean definition into DefaultBringBeanFactory.beanDefinitionMap by a name generated via AnnotationResolver. Beans are created based on these bean definitions.

Specified by:

registerBeanDefinition in interface BeanDefinitionRegistry

Parameters:

beanDefinition - The definition of the bean to be registered.

getOrCreateBean

public Object getOrCreateBean(String beanName)

Retrieves an existing bean with the given name from the container, or creates and registers a new bean if it doesn't exist.

Parameters:

beanName - The name of the bean to retrieve or create.

Returns:

An instance of the requested bean. If the bean already exists, the existing instance is returned; otherwise, a new instance is created and returned.
