本文整理了Java中org.hibernate.type.Type.isCollectionType()方法的一些代码示例，展示了Type.isCollectionType()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。Type.isCollectionType()方法的具体详情如下：
包路径：org.hibernate.type.Type
类名称：Type
方法名：isCollectionType

Type.isCollectionType介绍

[英]Return true if the implementation is castable to CollectionType. Essentially a polymorphic version of (type instanceof CollectionType.class)

A CollectionType is additionally an AssociationType; so if this method returns true, #isAssociationType() should also return true.
[中]如果实现可强制转换为CollectionType，则返回true。本质上是（type instanceof CollectionType.class）的多态版本
CollectionType另外是AssociationType；因此，如果这个方法返回true，#isAssociationType（）也应该返回true。
