public abstract class AbstractBeanOperationExecutor
extends Object
implements BeanOperationExecutor

This class serves as a template class and provides a basic skeleton implementation for most of the BeanOperationExecutor, particularly shielding the complexity of parsing DisassembleOperation operations. Once the executeOperations(java.util.List<cn.crane4j.core.executor.AssembleExecution>, cn.crane4j.core.executor.BeanOperationExecutor.Options) method is implemented in a subclass, it can be used as a BeanOperationExecutor.

According to the instructions specified in BeanOperations, the following steps are performed when executing operations through the BeanOperationExecutor.execute(java.util.Collection<?>, cn.crane4j.core.parser.BeanOperations, cn.crane4j.core.executor.BeanOperationExecutor.Options) method:

• If there are any DisassembleOperation operations to be executed, recursively extract and flatten the objects that need to be processed from the target object (if it is a collection or an array, iterate over each element);
• Group all the objects to be processed based on their corresponding BeanOperations, and wrap each group into an AssembleExecution object.
• Invoke the executeOperations(java.util.List<cn.crane4j.core.executor.AssembleExecution>, cn.crane4j.core.executor.BeanOperationExecutor.Options) method implemented in the subclass to actually perform the operations within each AssembleExecution.

This class only guarantees the sequential execution of DisassembleOperation operations, while the sequential execution of AssembleOperation operations depends on the implementation logic of executeOperations(java.util.List<cn.crane4j.core.executor.AssembleExecution>, cn.crane4j.core.executor.BeanOperationExecutor.Options).
For performance reasons, when implementing the executeOperations(java.util.List<cn.crane4j.core.executor.AssembleExecution>, cn.crane4j.core.executor.BeanOperationExecutor.Options) method, it is recommended to minimize the number of accesses to the Container.

waitTimeoutMillisecondIfOperationNotActive

public long waitTimeoutMillisecondIfOperationNotActive

Wait time in milliseconds if the operation is not active.
In normal cases, this time is unnecessary set to a large value, because the operation is usually active when the execute(java.util.Collection<?>, cn.crane4j.core.parser.BeanOperations, cn.crane4j.core.executor.BeanOperationExecutor.Options) method is called, Unless there is a circular dependency between the operation and the resolution of another object during the parsing process.

NOTE: This is not a good solution, so in future versions, we will try to solve this problem in the BeanOperationParser.

enableExecuteNotActiveOperation

public boolean enableExecuteNotActiveOperation

Whether to enable the execution of operations that are not active.

execute

public void execute(Collection<?> targets,
                    BeanOperations operations,
                    BeanOperationExecutor.Options options)

Complete operations on all objects in targets according to the specified BeanOperations and Options.

指定者:

execute 在接口中 BeanOperationExecutor

参数:

targets - targets

operations - operations to be performed

options - options for execution

createAssembleExecution

protected AssembleExecution createAssembleExecution(BeanOperations beanOperations,
                                                    AssembleOperation operation,
                                                    Collection<Object> targets,
                                                    BeanOperationExecutor.Options options)

Create a AssembleExecution.

参数:

beanOperations - bean operations

operation - operation

targets - targets

options - options for execution

返回:

AssembleExecution

executeOperations

protected abstract void executeOperations(List<AssembleExecution> executions,
                                          BeanOperationExecutor.Options options)
                                   throws OperationExecuteException

Complete the assembly operation.
All operations of input parameters ensure their orderliness in the same class. For example, if there are ordered operations a and b in A.class, the order of a and b is still guaranteed when the corresponding AssembleExecution is obtained.

参数:

executions - assembly operations to be completed

options - options for execution

抛出:

OperationExecuteException - thrown when operation execution exception

tryExecute

protected static void tryExecute(Runnable execute)

Try to execute the operation.
If necessary, output the log when throwing an exception.

参数:

execute - execute
