本文整理了Java中org.apache.james.mime4j.stream.Field类的一些代码示例，展示了Field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。Field类的具体详情如下：
包路径：org.apache.james.mime4j.stream.Field
类名称：Field

Field介绍

[英]This interface represents an abstract MIME field. A MIME field must have a non null name and a content body (unfolded but unparsed and possibly encoded). Optionally implementing classes may also retain the original (raw) representation in a form of ByteSequence.

Specific implementations of this interface may also use a richer model to represent the field if its body can be parsed into a set of constituent elements.
[中]此接口表示一个抽象MIME字段。MIME字段必须具有非null名称和内容正文（展开但未分析，可能已编码）。可选地，实现类还可以以字节顺序的形式保留原始（原始）表示。
如果字段的主体可以解析为一组组成元素，则此接口的特定实现也可以使用更丰富的模型来表示字段。
