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

Type.getSize介绍

[英]Returns the size of values of this type. This method must not be used for method types.
[中]返回此类型值的大小。此方法不能用于方法类型。
