接口 AssembleOperation

所有超级接口:

Comparable<Sorted>, Grouped, KeyTriggerOperation, Sorted

所有已知实现类:

SimpleAssembleOperation

public interface AssembleOperation
extends KeyTriggerOperation

表示一个由指定的键触发的装配操作。
它通常通常用来描述通过下述步骤完成的依次填充操作：

1. 提取目标对象的键字段值；
2. 通过指定的数据源容器将键值转换为对应的数据源对象；
3. 将数据源对象的特定属性值映射到目标对象的属性中；

完成上述操作所需的组件或配置可以通过方法获取：

1. KeyTriggerOperation.getKey()：目标对象的哪个字段是键字段；
2. getContainer()：通过键字段值获取对应的数据源对象的容器；
3. getPropertyMappings()：获取数据源对象后，哪些属性应该填充到目标对象的哪些属性中；
4. getAssembleOperationHandler()：如何将这些属性值插入；
5. getKeyResolver()：如何解析键；
6. getKeyDescription()：键的描述；
7. getPropertyMappingStrategy()：属性映射策略；
8. getKeyType()：键的类型；

The assembly operation triggered by the specified key.
An example is usually used to describe one of the following processes:

1. extract a key field value of the target object;
2. convert the key value to the corresponding data source object through the specified data source container;
3. map the specific attribute values of the data source object to the attributes of the target object;

The necessary parts for completing the above operations can be obtained through the instance:

1. KeyTriggerOperation.getKey(): which field of the target object is the key field;
2. getContainer(): which container to get the corresponding data source object through the key field value;
3. getPropertyMappings(): after getting the data source object, which attributes should be stuffed into which attributes of the target object;
4. getAssembleOperationHandler(): how to plug these attribute values;
5. getKeyResolver(): how to resolve the key;
6. getKeyDescription(): description of the key;
7. getPropertyMappingStrategy(): property mapping strategy;
8. getKeyType(): key type;
