本文整理了Java中org.eclipse.persistence.internal.helper.Helper.areTypesAssignable()方法的一些代码示例，展示了Helper.areTypesAssignable()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。Helper.areTypesAssignable()方法的具体详情如下：
包路径：org.eclipse.persistence.internal.helper.Helper
类名称：Helper
方法名：areTypesAssignable

Helper.areTypesAssignable介绍

[英]PUBLIC: Compare two vectors of types. Return true if the size of the vectors is the same and each of the types in the first Vector are assignable from the types in the corresponding objects in the second Vector.
[中]公共：比较两种类型的向量。如果向量的大小相同，并且第一个向量中的每个类型都可以从第二个向量中相应对象中的类型进行赋值，则返回true。
