public interface AssembleOperationHandler
extends NamedComponent

Handler of assembly operation.
Enter the assembly operation and the corresponding type of object to be processed. then it will complete the following operations according to the configuration：

1. extract key value from target objects；
2. convert the key value to the corresponding data source object through the data source container；
3. complete the mapping of data source object attributes and pending object attributes；

For performance reasons, the implementation class needs to minimize the reading and writing of beans and the requests for data source containers.
