public interface Container<K>

The source container used to store the provided data objects.
The data source that can be used to complete the assembly operation. Any Map set object method that can accept the key value set and return grouping by key value can be used as a data source.

Lifecycle

All container instances support registering callback functions during specific stages of their lifecycle, including:

• When registered: when the container is registered as a ContainerDefinition instance to the ContainerManager;
• When created: when the container transitions from a ContainerDefinition to an actual instance;
• When destroyed: when the container instance is destroyed, this behavior may not affect the corresponding ContainerDefinition;

By extending the ContainerLifecycleProcessor(for all containers) or implementing Container.Lifecycle(for specified container class), users can perceive these specific stages and perform modifications and replacement operations on the container.

Manger

Containers are typically not used directly in specific operations, but rather managed by a designated ContainerManager that handles the creation, usage, and destruction process.
This allows the associated ContainerLifecycleProcessor to fully handle the container's lifecycle.

When delegating the container to the manager, you can directly register an instance or a factory method used to create the instance with the manager. Alternatively, you can register a ContainerProvider, allowing the container to automatically complete the registration logic when necessary, similar to the internal BeanFactory in Spring, where beans are created using FactoryBean.

方法详细资料

empty

static <K> Container<K> empty()

Get an empty data source container.
When an assembly operation specifies to use the data source container, the operation object itself will be used as the data source object.

返回:

container

EmptyContainer

getNamespace

String getNamespace()

Gets the namespace of the data source container, which should be globally unique.

返回:

namespace

get

Map<K,?> get(Collection<K> keys)

Enter a batch of key values to return data source objects grouped by key values.

参数:

keys - keys

返回:

data source objects grouped by key value
