Subject [jira] [Commented] (LANG-778) Add UUIDUtils.toByteArray and UUIDUtils.fromByteArray
Date Tue, 22 Nov 2011 15:40:40 GMT

    [ https://issues.apache.org/jira/browse/LANG-778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13155208#comment-13155208
] 

Sebb commented on LANG-778:
---------------------------

Could perhaps consider a method such as

int ByteUtils.longToByteArray(long input, byte[] buffer, int offset)

This could then be used twice in the UUID class, as well as being used in

byte[] ByteUtils.longToByteArray(long input).

Just a thought.

It seems a shame not to be able to use the long=>ba conversion elsewhere.

> A UUID represents 16 bytes. In some situation (e.g. using DBs that do not have native
support for the type UUID) it is necessary to use directly the bytes. The JDK does not support
the transformation from UUID to bytes and back, therefore I'd like to add UUIDUtils with the
two proposed methods.
