AssembleOperationHandler

public class ManyToManyAssembleOperationHandler
extends OneToManyAssembleOperationHandler

An implementation of AssembleOperationHandler for the one-to-one mapping between the target object and the data source object.

The difference between ManyToManyAssembleOperationHandler and OneToManyAssembleOperationHandler is that OneToManyAssembleOperationHandler is used to handle the situation where multiple values can be obtained through a key in the data source container, while ManyToManyAssembleOperationHandler is used to handle the situation where only one value can be obtained through a key, but there are multiple keys at the same time.

ManyToManyAssembleOperationHandler

public ManyToManyAssembleOperationHandler(PropertyOperator propertyOperator,
                                          Function<Object,Collection<Object>> keySplitter)

Create an ManyToManyAssembleOperationHandler comparator.

参数:

propertyOperator - propertyOperator

ManyToManyAssembleOperationHandler

public ManyToManyAssembleOperationHandler(PropertyOperator propertyOperator)

Create a ManyToManyAssembleOperationHandler comparator and use the default ManyToManyAssembleOperationHandler.DefaultSplitter split key value

参数:

propertyOperator - property operator

方法详细资料

createTarget

protected AbstractAssembleOperationHandler.Target createTarget(AssembleExecution execution,
                                                               Object origin,
                                                               Object keyValue)

Create a Target comparator.

覆盖:

createTarget 在类中 OneToOneAssembleOperationHandler

参数:

execution - execution

origin - origin

keyValue - key value

返回:

Target

getSourcesFromContainer

protected Map<Object,Object> getSourcesFromContainer(Container<?> container,
                                                     Collection<AbstractAssembleOperationHandler.Target> targets)

Obtain the corresponding data source object from the data source container based on the entity's key value.

覆盖:

getSourcesFromContainer 在类中 OneToOneAssembleOperationHandler

参数:

container - container

targets - targets

返回:

source objects

getTheAssociatedSource

protected Object getTheAssociatedSource(AbstractAssembleOperationHandler.Target target,
                                        Map<Object,Object> sources)

Get the data source object associated with the target object.

覆盖:

getTheAssociatedSource 在类中 OneToOneAssembleOperationHandler

参数:

target - target

sources - sources

返回:

data source object associated with the target object
