类名称：Marker

Marker介绍

[英]Markers are objects that are used to add easily filterable information to log messages. Markers can be hierarchical - each Marker may have a parent. This allows for broad categories being subdivided into more specific categories. An example might be a Marker named "Error" with children named "SystemError" and "ApplicationError".
[中]标记是用于向日志消息添加易于过滤的信息的对象。标记可以是分层的——每个标记可能有一个父标记。这允许将广泛的类别细分为更具体的类别。例如，一个名为“Error”的标记，其子项名为“SystemError”和“ApplicationError”。
