本文整理了Java中org.apache.log4j.spi.Filter.decide()方法的一些代码示例，展示了Filter.decide()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。Filter.decide()方法的具体详情如下：
包路径：org.apache.log4j.spi.Filter
类名称：Filter
方法名：decide

Filter.decide介绍

[英]If the decision is DENY, then the event will be dropped. If the decision is NEUTRAL, then the next filter, if any, will be invoked. If the decision is ACCEPT then the event will be logged without consulting with other filters in the chain.
[中]如果决策为DENY，则事件将被删除。如果决策为NEUTRAL，则将调用下一个筛选器（如果有）。如果决定为“接受”，则将记录事件，而无需咨询链中的其他筛选器。
