包路径：uk.gov.dstl.baleen.core.utils.yaml.YamlConfiguration
类名称：YamlConfiguration

YamlConfiguration介绍

[英]A helper to deal with YAML files and their basic map representation.

Configuration can be accessed by a path representation e.g.:

"logging.enabled"

This class also contains helper methods to get a type safe value from the YAML configuration.
[中]处理YAML文件及其基本地图表示的助手。
可通过路径表示访问配置，例如：

"logging.enabled"

该类还包含从YAML配置获取类型安全值的帮助器方法。
