　　Based on the "in-depth understanding of Java Virtual Machines", this book summarizes　　I. About several concepts: (tag garbage algorithm, garbage collection algorithm, garbage collector)There are two ways to find JVM garbage: The reference counting method/accessibility algorithm. This preparation, after marking the garbage, the recovery algorithm, where the algorithm is just garbage collection idea. There will be a variety of garbage collectors, the

　　What memory needs to be recycled?Java Memory Runtime area of the various parts, where the program counter, virtual machine stack, the local method stack 3 regions with the thread, with the thread, the stack frame in the stack with the method entered and exited with a non-flocculation of the execution of the stack and into the stack operation. How much memory is allocated in each stack frame is basically known when the class structure is determined. Therefore, memory allocation and recycling ar

garbage collector is concerned with this part of the memory.Heap memory for this large number of object instances, the garbage collector first infers which of these objects are "alive" and which are "dead"The reference counter algorithm adds a reference counter to the object and adds 1 to the counter whenever it is referenced. Calculator minus one when you lose a quote.At any given moment, a calculator val

equates to a 10% wasted memory point;If the 10% to survivor space is not sufficient to store the surviving object, the old age is required for the allocation guarantee (the surviving object is directly into the old age through the distribution guarantee mechanism)3, marker-collation algorithmDefinition: First mark the object to be reclaimed, move the surviving object to one end, and finally clear the memory outside the end boundary　　　　　　4, generation of collection algorithmDefinition: The memor

Because of the project needs, I will replace the common.js with Build.min.js, and then use the build.min.js=> Build-te234ds.min.js such a form of substitution, but I found that how to replace the Common.js can not be replaced, after analysis found that:Only the name conforms to the standard to replace the success, not manually modify the file to the time when the modification is unsuccessful, such as common.js=>common-tes234.js, such as the form of success, and not like common.js->build.min.js.R

Recently, when I changed the away3d source code, I encountered a very depressing problem and found that the created mesh cannot be released. Source code analysis found that the logic bug in the entitylistitempool class is found in the getitem () function. If the _ poolsize Object pool size is sufficient, the method used is to reuse entitylistitem. If I have deleted 10 objects in the scenario, I have deleted them all, and then I have created nine more objects. At this time, one object is always c
