本文整理了Java中org.apache.hadoop.hbase.regionserver.Region.checkAndMutate
方法的一些代码示例,展示了Region.checkAndMutate
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。Region.checkAndMutate
方法的具体详情如下:
包路径:org.apache.hadoop.hbase.regionserver.Region
类名称:Region
方法名:checkAndMutate
[英]Atomically checks if a row/family/qualifier value matches the expected value and if it does, it performs the mutation. If the passed value is null, the lack of column value (ie: non-existence) is used. See checkAndRowMutate to do many checkAndPuts at a time on a single row.
[中]原子地检查行/族/限定符值是否与预期值匹配,如果匹配,则执行变异。如果传递的值为null,则使用缺少列值(即:不存在)。请参阅checkAndRowMutate,一次在一行上执行多个checkAndPuts。
