接口 AssembleOperation

所有超级接口:

Grouped, KeyTriggerOperation, Sorted

所有已知实现类:

SimpleAssembleOperation

public interface AssembleOperation
extends KeyTriggerOperation

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 components for completing the above operations can be obtained through the comparator:

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;
