Elliotte Rusty Harold commented on IO-236:
------------------------------------------
seems like an uncommon need and mostly well handled by other methods and APIs
that exist today, including BoundedInputStream. I recommend closing this one as
won't do.
> Add "Read" Methods With Size Limits to FileUtils
> ------------------------------------------------

> Key: IO-236
> URL: https://issues.apache.org/jira/browse/IO-236
> Project: Commons IO
> Issue Type: Improvement
> Components: Utilities
> Affects Versions: 2.0
> Environment: 1.4+
> Reporter: Michael Wooten
> Priority: Minor
> Fix For: 3.x
>
> Original Estimate: 6h
> Remaining Estimate: 6h

> I suggest adding versions of the utility methods for reading lines and
> Strings from a file that also accept a limit on the number of bytes or lines
> that should be read. I propose that the following methods be added:
> String readFileToString(File file, long byteCountToRead)
> String readFileToString(File file, String encoding, long byteCountToRead)
> byte[] readFileToByteArray(File file, long byteCountToRead)
> byte[] readFileToByteArray(File file, String encoding, long byteCountToRead)
> List<String> readLines(File file, long lineCountToRead)
> List<String> readLines(File file, String encoding, long lineCountToRead)
> One of the drawbacks I have encountered to using the methods in the past is
> that I only needed to read a limited number of bytes or lines from a file and
> I had to read the entire file. This can be especially dangerous if run on a
> file that is quite large, and only a portion of the file is needed.
