本文整理了Java中org.apache.geode.cache.execute.Execution.withFilter()方法的一些代码示例，展示了Execution.withFilter()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.withFilter()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：withFilter

Execution.withFilter介绍

[英]Specifies a data filter of routing objects for selecting the GemFire members to execute the function on.

Applicable only for regions with DataPolicy#PARTITION DataPolicy. If the filter is null, it will execute on all data of the region.
[中]指定路由对象的数据筛选器，用于选择要在其上执行函数的GemFire成员。
仅适用于具有DataPolicy#分区DataPolicy的区域。如果筛选器为空，则它将对该区域的所有数据执行。

@Override
public int size() {
 // Add a single dummy key to force the function to go to one server
 Set<String> filters = new HashSet<String>();
 filters.add("test-key");
 // Execute the function on the session region
 Execution execution = FunctionService.onRegion(getSessionRegion()).withFilter(filters);
 ResultCollector collector = execution.execute(RegionSizeFunction.ID);
 List<Integer> result = (List<Integer>) collector.getResult();
 // Return the first (and only) element
 return result.get(0);
}
