[jira] [Created] (IO-486) FileUtils.readFileToString() can
immediately return empty string if file length is zero
Viktor Isaev created IO-486:
-------------------------------
Summary: FileUtils.readFileToString() can immediately return empty string if file length is zero
Key: IO-486
URL: https://issues.apache.org/jira/browse/IO-486
Project: Commons IO
Issue Type: Improvement
Reporter: Viktor Isaev
If {{file.length() == 0}}, there is no point of doing extra work of opening and closing an input stream - we can return an empty string right away.
Same applies for {{FileUtils.readFileToByteArray()}} and {{FileUtils.readLines()}}.
