dominator memory

space in which an object is freed up by GC after it is reclaimed.This figure can read what is leading set and what is retained set.Dominator Tree: Defines an object x dominate object Y, when each path from root to Y is x. The white is that as long as there is a Y object to survive, then there must be an X object. Dominator trees are the tree structures in which the object reference graph is converted. It helps to discover the alive dependencies betwe

useful tools at the bottom of this pie chart, so let's take a look at it.histogram can list the name, number, and size of each object in memory.Dominator Tree sorts all in-memory objects by size, and we can parse the reference structure between objects.Generally the most commonly used is the above two functions, then we start from Dominator Tree began to learn.Now click on

Android obtains the total memory and available memory of the mobile phone. In Android development, sometimes we want to obtain some hardware information about the mobile phone, such as the total memory and available memory size of the Android phone. How can this be implemented?By reading the "/proc/meminfo" file, you c

How to set the optimal 4G memory virtual memory ?, 4G memory virtual memory Memory is one of the important components in the computer and serves as a bridge to communicate with the CPU. So, do you know how much virtual memory sho

open the exported hprof file. Open the interface as shown in the following illustration: The most commonly used in mat is the histogram and Dominator tree, which correspond to the A and B buttons in the above picture respectively. Histogram can see the number of different types of buffer in memory and the size of memory consumed, while

From the compiler perspective, memory is divided into three situations: 1. The memory area that has been determined during system initialization and will not change. It generally refers to global variables and static variable arrays. 2. memory on the stack: generally refers to the local variables in the function. The memory
