Do not modify the key object of MAP after it is used. If it must be modified, delete it and insert it again.
The key-value of multimap is one-to-multiple, and the [] operator is not overloaded.

operator precedence, you can take an operator group that defines only the increment priority, and then calculate the priority of each operator by calculating the precedence level. This saves a lot of pre-calculations on the priority level.precedenceVariables are mappings from operators to their precedence, integers starting at 0. It is calculated from a for expression with two generators. The first generator produces opGroups each index of the array i . The second generator produces each of the

Aside from Android itself, our understanding of the transaction mainly stems from the database, that is, a batch of operations, recording your collection of operations, and then one-time processing, to ensure the security and efficiency of transaction pr
I have never had a deep understanding of the concept of AOP until I have finished reading Agent Oriented programmig (AOP) [1. I may have the opportunity to have a better understanding in the future, but I want to record my thoughts after reading this blog today, although such thinking may be naive. I don't have much knowledge about these concepts. If you have any mistakes, please correct them. (I think it is more efficient to get the knowledge through communication ).
