weakreference

WeakReference and SoftReference, weakreference SoftReference (soft reference) and WeakReference (weak reference) are two classes used for java objects in heap. These two classes can be used for simple interaction with gc.   WeakReference is a weak

We usually use a strong reference to the object, and if a strong reference exists, the GC does not reclaim the object. Can we keep a reference to the object at the same time and let the GC recycle the object when it's needed? NET provides the

Java. Lang. Ref is introduced in Java 1.2, and weakreference belongs to this package. What does weakreference do? The disadvantage is that it is related to garbage collection in Java. If only weakreference references an object, the object may be

In versions earlier than JDK, when an object is not referenced by any variable, the program will no longer be able to use this object. That is to say, the program can use the object only when it is reachable. This is like in daily life, after buying

The Java 2 platform introduces the JAVA.LANG.REF package, which includes classes that allow you to reference objects without leaving them in memory. These classes also provide limited interaction with the garbage collector (garbage collector).1. The

SoftReference soft reference of Android learning notes; weak references: WeakReference and weakreference SoftReference can be used for bitmap caching WeakReference can be used for handler     private Handler mRemoteHandler = new SafeHandler(this);

Juce in the WeakReference design is more ingenious, clever is to use the delete after you can inform the WeakReference, the principle is also very single, in fact, is in the object added a sub-object masterreference, The object is actively called

Reference is an abstract class, and Softreference,weakreference,phantomreference and finalreference are the concrete classes that inherit it.Next, we will introduce and analyze the characteristics and usages of the strong references and the various

Introduction: See a post, a foreign technical interviewer in the interview senior Java developer, asked a weak reference related issues. He did not expect anyone to fully explain what weak reference was, how to use it, just to expect someone to
