包路径：com.hp.hpl.jena.graph.Graph
类名称：Graph

Graph介绍

[英]The interface to be satisfied by implementations maintaining collections of RDF triples. The core interface is small (add, delete, find, contains) and is augmented by additional classes to handle more complicated matters such as reification, query handling, bulk update, event management, and transaction handling.

For add(Triple) see GraphAdd.
[中]维护RDF三元组集合的实现需要满足的接口。核心接口很小（添加、删除、查找、包含），并通过附加类进行扩展，以处理更复杂的事务，如物化、查询处理、批量更新、事件管理和事务处理。
有关add(Triple)的信息，请参见GraphAdd。
