Util.isLangString介绍

[英]A Node is a language string if it has a language tag. (RDF 1.0 and RDF 1.1)
[中]如果一个节点有一个语言标记，那么它就是一个语言字符串。（RDF 1.0和RDF 1.1）

代码示例

 * (RDF 1.0 and RDF 1.1)

代码示例来源：origin: apache/jena

/** Return true if the literal is a simple string.
 *  <p>RDF 1.0 {@literal =>} it is a plain literal, with no language tag
 *  <p>RDF 1.1 {@literal =>} it has datatype xsd:string
