类名称：Rio
方法名：createParser

Rio.createParser介绍

[英]Convenience methods for creating RDFParser objects. This method uses the registry returned by RDFParserRegistry#getInstance() to get a factory for the specified format and uses this factory to create the appropriate parser.
[中]创建RDFParser对象的便捷方法。此方法使用RDFParserRegistry#getInstance（）返回的注册表获取指定格式的工厂，并使用此工厂创建适当的解析器。
