包路径：org.neo4j.graphdb.Relationship
类名称：Relationship
方法名：getType

Relationship.getType介绍

[英]Returns the type of this relationship. A relationship's type is an immutable attribute that is specified at Relationship Node#createRelationshipTo. Remember that relationship types are semantically equivalent if their RelationshipType#name() are Object#equals(Object). This is NOT the same as checking for identity equality using the == operator. If you want to know whether this relationship is of a certain type, use the #isType(RelationshipType)operation.
[中]返回此关系的类型。关系的类型是在关系节点#createRelationshipTo指定的不可变属性。记住，如果关系类型的RelationshipType#name（）是Object#equals（Object），那么它们在语义上是等价的。这与使用==运算符检查标识相等不同。如果想知道此关系是否属于某种类型，请使用#isType（RelationshipType）操作。
