本文整理了Java中org.apache.geode.cache.execute.Execution.setArguments()方法的一些代码示例，展示了Execution.setArguments()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Execution.setArguments()方法的具体详情如下：
包路径：org.apache.geode.cache.execute.Execution
类名称：Execution
方法名：setArguments

Execution.setArguments介绍

[英]Specifies the user data passed to the function when it is executed. The function can retrieve these arguments using FunctionContext#getArguments()
[中]指定执行函数时传递给函数的用户数据。函数可以使用FunctionContext#getArguments（）检索这些参数

private void createSessionRegionOnServers() {

 // Send it to the server tier
 Execution execution = FunctionService.onServer(this.cache).setArguments(configuration);
 ResultCollector collector = execution.execute(CreateRegionFunction.ID);
 // Verify the region was successfully created on the servers
 List<RegionStatus> results = (List<RegionStatus>) collector.getResult();
 for (RegionStatus status : results) {
  if (status == RegionStatus.INVALID) {
   StringBuilder builder = new StringBuilder();
   builder.append(
     "An exception occurred on the server while attempting to create or validate region named ");
   builder.append(properties.get(CacheProperty.REGION_NAME));
   builder.append(". See the server log for additional details.");
