I've found several other threads on SO about using PowerShell to rename files, but none of them handled

问题 I'm using log4j 2 and RollingFile appender: <RollingFile name="mylog" fileName="mylog.log" filePattern="mylog.log.%d{yyyy-MM-dd}.log"> <PatternLayout> <pattern>[%d] [%-5p] [%-8t] %F:%L %m%n</pattern> </PatternLayout> <Policies> <TimeBasedTriggeringPolicy interval="1"/> </Policies> </RollingFile> The log files do get renamed daily.

The script reads the file's creation date and time, and rename the file accordingly. The prefix will be added to the front of the

问题 I would like to "rename" some members of my class ofVec4f . I know it's impossible in strict C++ but could I create a new class that inherits from my class and declare new members which are aliases or pointers to the original members?
