When you get the field ID and the method ID , you need to do a search with the field, the name of the method, and the descriptor. The retrieval process is relatively time-consuming, so this section discusses using caching techniques to reduce the cost of this process. There are two main ways to cache field IDs and method IDs . The two differences are primarily in the time at which the cache occurs, when the

We know that when a style table defines a style, you can define the id or class, for example:ID method: # test {color: #333333}. On the page, call CLASS method:. test {color: #333333}. On the page, call Id: a page can be used only once, and the class can be referenced multiple times.Some netizens asked, the id and class seem to be no different. I used multiple IDs on the page to display them normally in IE. What is the impact of using multiple

NIDs uses the original network information as the data source, uses the network adapter running in the random mode to monitor and analyze all the communication through the network, collects the relevant information and logs it, while HIDs is usually installed on the detected host and connects with the host's network in real time. Responsible for the intelligent analysis and judgment of the system audit log. If an illegal intrusion or violation of statistical laws is found,

the firewall security policy setting function, it can immediately block attack actions, but this blocking action can only be applied to TCP sessions, it must be completely limited, it is necessary to re-adjust the firewall security policy setting function, and may also cause another anti-effect: the instant blocking action will allow attackers to discover the existence of IDS, attackers usually look for ways to circumvent or attack

When hashcode is used, the same ID will appear, although the probability is very small. Although it is not the reason for hashcode, it is another logic problem. However, I tried to write an ID generator myself. Some IDs are int, for example, task id, and some IDs are long, for example, player ID. First paste the code to see: Private Static atomicinteger id = new atomicinteger (0); public static long GETI

snowflake algorithm. The benefits of this algorithm are simple enough to produce approximately 400W different 16-bit digital IDs per second (10 binary) The principle is simple. ID is made up of 64bit One of the first bit vacancies 41bit for storing millisecond timestamps 10bit for storing machine ID 12bit for storing self-increment ID In addition to the top bit marked as unavailable, the remaining three sets of bit placeholders can be floated to see
