本文整理了Java中org.apache.jena.rdf.model.Model.union()方法的一些代码示例，展示了Model.union()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。Model.union()方法的具体详情如下：
包路径：org.apache.jena.rdf.model.Model
类名称：Model
方法名：union

Model.union介绍

[英]Create a new, independant, model containing all the statements in this model together with all of those in another given model. By independant we mean that changes to the result model do not affect the operand models, and vice versa.

The new model need not be of the same type as either this model or the argument model: typically it will be a memory-based model, even if this model is a database model.
[中]创建一个新的独立模型，包含此模型中的所有语句以及另一个给定模型中的所有语句。所谓独立，我们的意思是对结果模型的更改不会影响操作数模型，反之亦然。
新模型不必与此模型或参数模型的类型相同：通常它将是基于内存的模型，即使此模型是数据库模型。
