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

Execution.execute介绍

[英]Executes the function using its Function#getId()

Function#execute(FunctionContext) is called on the instance retrieved using FunctionService#getFunction(String) on the executing member.
[中]使用函数#getId()执行函数
函数#execute(FunctionContext)在执行成员上使用FunctionService#getFunction(String)检索的实例上调用。
