本文整理了Java中org.geotools.ysld.YamlSeq类的一些代码示例，展示了YamlSeq类的具体用法。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。YamlSeq类的具体详情如下：
包路径：org.geotools.ysld.YamlSeq
类名称：YamlSeq

YamlSeq介绍

[英]Wrapper around a parsed Yaml sequence.

Wrapper requires List as sequence order is required.
[中]包装已解析的Yaml序列。
包装器需要列表，因为序列顺序是必需的。
