[jira] [Commented] (IO-349) Add array offset and length argument to
FileUtils.writeByteArrayToFile
[ https://issues.apache.org/jira/browse/IO-349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13483139#comment-13483139 ]
David Bild commented on IO-349:
-------------------------------
No comments? Is this functionality already available and I just missed it? Seems like a pretty simple patch to accept if not.

> The FileUtils.writeByteArrayToFile method does not allow a subset of an array to be written to a file. Instead, the subset must be copied to a separate array, increasing the lines of code and (for all JVMs I know about) runtime.
> Sister methods that take an offset and length should be added, inline with the byte array-oriented methods in the Java standard library.
> Attached is a patch that implements FileUtils.writeByteArrayToFile(File file, byte[] data, int offset, int length) and FileUtils.writeByteArrayToFile(File file, byte[] data, int offset, int length, boolean append) and associated testcases in FileUtilsTestCase.java.
