FileUtils.readSmallFile介绍

[英]A utility routine to read a text file efficiently and return the contents as a String. Sometimes while reading log files of spawned processes this kind of facility is handy. Instead of opening files, coding FileReaders etc. this method could be employed. It is expected that the file to be read is small.
