链滴 Java 源码剖析——彻底搞懂 Reference 和 ReferenceQueue 作者：jesministrator 原文链接：https://ld246.com/article/1513083921948 来源网站：链滴 许可协议：署名-相同方式共享 4.0 国际 (CC BY-SA 4.0) 之前博主的一篇读书笔记——《深入理解Java虚拟机》系列之回收对象算法与四种引用类型博客中为 的原理进行更深入 了解。因此博主查看了抽象父类Reference和负责注册引用对象的引用队列ReferenceQueue的源码 在此和大家一起分享，并做了一些分析，感兴趣的同学可以一起学习。 Reference源码分析 首先我们先看一下Reference类的注释： /** * Abstract base class for reference objects. This class defines defines the * operations common to all reference objects. Because reference objects are * implemented in close cooperation with the garbage collector, this class may * not be subclassed directly. 引

Blender 4.1 Reference Manual Welcome to the manual for Blender, the free and open source 3D creation suite. Getting Started Getting Started About Blender Installing Blender Configuring Blender Help Blender after a few hours of practice. This manual is a good start, though it serves more as a reference. There are also many online video tutorials from specialized websites. Despite everything Blender and usually not highly experimental. Note Blender’s source code is available for free to either reference or to Build from Source. While normal users are not expected to compile Blender, it does have advantages:

By choosing a new symbol in the New Library Reference column, you can make all instances of the existing symbol instead point to the new symbol. If the the same name in an active library.

not selected. No DRC checking is done when moving footprints with the Move command. There is a reference point for the move operation, which is the point in the footprint which attaches to the cursor objects. The reference point during a move is determined by the location of the cursor when the Move command is initiated. If the cursor is over a pad, the pad’s center will be used as the reference point. the Move With Reference command instead of the regular Move command (right click → Positioning Tools → Move with Reference). After initiating the command, click on the desired reference point; KiCad will
